Appendix 27.3 Data Types a nd Farameter Types

27.3.3.6

Using User-Defined Data Types to Access Data

User-Defined Data Types User-defined data types (UDTs) can combine elementary and complex data types. You can assign a name to UDTs and use them more than once. The following figure illustrates the structure of a user-defined data type consisting of an integer, a byte, a character, a floating-point number, and a Boolean value.

UDT20 I NT BYTE C h ftR

Integer Byte Character

REAL

Real number

---------------

BOOL

----------- ►-

Boolean value

Instead of entering all the data types singly or as a structure, you only need to specify "UDT20" as the data type and STEP 7 automatically assigns the corresponding memory space.

Creating a User-Defined Data Type You define UDTs with STEP 7. The following figure shows a UDT consisting of the following elements: an integer (for saving the amount), a byte (for saving the original data), a character (for saving the control code), a floating-point number (for saving the temperature), and a Boolean memory bit (for terminating the signal). You can assign a symbolic name to the UDT in the symbol table (for example, process data). Address Name 0.0 3tack_1 +0.0 Amount Original_data +2.0 +4.0 Control_code Temperature +6.0 End +8.0 =10.0

Type STRUCT INT BYTE CHAR REAL BOOL END_STRUCT

120 FALSE

Once you have created a UDT, you can use the UDT like a data type if, for example, you declare the data type UDT200 for a variable in a DB (or in the variable declaration of an FB). The following figure shows a DB with the variables process_data_1 with the data type UDT200. You only specify UDT200 and process_data_1. The arrays shown in italics are created when you compile the DB. Address 0.0 +10.0 =10.0

Appenaix 27.3 Data Types and Patameier Types

Assigning Initial Values for a User-Defined Data Type If you want to assign an initial value to every element of a user-defined data type, you specify a value that is valid for the data type and the name of the element. You can, for example, assign the following initial values (to the user-defined data type declared in the above figure): Amount = Original_data Control_code Temperature End

100 B#16#0) 'C '

1.200000e+002 False

If you declare a variable as a UDT, the initial values of the variables are the values you specified when you created the UDT.

Saving and Accessing Data in a User-Defined Data Type You access the individual elements of a UDT. You can use symbolic addresses (for example Stack_1 .Temperature). You can, however specify the absolute address at which the element is located (example: if Stack_1 is located in DB20 starting at byte 0, the absolute address for amount is DB20.DBW0 and the address for temperature is DB20.DBD6).

Using User-Defined Data Types as Parameters You can transfer variables of the data type UDT as parameters. If a parameter is declared as UDT in the variable declaration, you must transfer a UDT with the same structure. An element of a UDT can, however, also be assigned to a parameter when you call a block providing the element of the UDT corresponds to the data type of the parameter.

Note If you call a block created in the S7-SCL programming language that contains a UDT parameter in the program editor, this can result in a type conflict. You should therefore avoid using blocks created in SCL if you use UDTs.


607

Appendix 27.3 Data Types a nd Farameter Types

Advantages of DBs with an Assigned UDT By using UDTs you have created once, you can generate a large number of data blocks with the same data structure. You can then use these data blocks to enter different actual values for specific tasks. If, for example, you structure a UDT for a formula (for example, for blending colors), you can assign this UDT to several DBs each containing different amounts.

The structure of the data block is determined by the UDT assigned to it.

Exercise

Compile and download your AS's hardware configuration to your target module.

Compile

Click the Save and Compile icon ("1" in the slide). Or, alternatively, you can use the menu command Station -> Save and Compile

Download

Ensure that the CPU is in STOP mode and that the keyswitch is set to STOP or RUN_P. Click the icon *2" or, alternatively, use the menu command PLC -> Download to Module The first time you download, the AS is downloaded with the CPU in STOP mode (if it is still running with an old configuration, the download dialog box offers a stop and restart option). If you make changes later, they can also be downloaded w ith the CPU in RUN mode (certain rules apply). This assumes th at suitable PCS 7 driver blocks are already running in the CPU.

Remark

For the sake of completeness, a description of downloading in RUN mode is provided on the following pages. If you need to make changes to the hardware configuration during the course of the project, follow the download procedure described there. Now the configuration of the AS from the first project is complete. A similar procedure must also be performed for the PC stations that are being used as ES or OS (see the section "Configuring the PC Station” in this chapter).

Process description (using the equipm ent in Group 1, U nit A1 as an example): Component X

The reactor must first be empty and cold. Valve 1U101 is used to fill this component up to the L1=20% Lmax level.

Mixer

The mixer motor 1E101 is turned on.

Component Y

Valve 1U102 is used to mix this second component until the L2=80% Lmax level is reached.

Heating

The mixture is heated up to 90°C. The temperature controller 1T101 must maintain this temperature for at least two minutes.

Draining

After the heating is turned off, product Z must be drained completely, and the mixer 1E101 must be turned off.

In addition

The fill level is monitored (1L101 and 1L102). The inlet valves 1U101 and 1U102 must be closed when the upper level limit (Lmax) is reached. The drain valve must be closed when the reactor is empty. There must be a signal when the level monitor responds. Both the temperature controller and the mixer must be operated and monitored in the control room.

Download to target system in RUN Requirements

A fte r the station configuration was downloaded w ith CPU STOP, you made changes to the configuration and have not saved them yet. In the hardware configuration select PLC -> Download to Module or click the icon (point 1 in the slide) The CPU keyswitch m ust be set to RUN_P. Then download in RUN state is offered. Should the CPU nevertheless go to STOP as a result of downloading in RUN, this is an indication that the CPU software is incomplete or does not capture the triggered events. This problem is automatically solved by using the PCS 7 driver blocks.

After the download procedure is started in RUN, STEP 7 first checks whether the changes can be downloaded in RUN. The current online configuration of the CPU is also taken into account. If it is not possible to download the changes (e.g. offline changes to the CPU parameters, such as e.g. PIP assignment), a screen is displayed indicating the cause. You can then press the Help button to display a description of the error and how it can be eliminated (if this is possible). You can also start a preliminary check of the CiR compatibility by activating the menu option in the HW Config Station -> Check CiR Compatibility This checks whether the configuration changes that were made since the last download can be downloaded to the automation system in RUN. The check is performed offline. An online connection is not required.

If the check returns a negative result, we recommend discarding the changes. You are lucky if you didn't save the modified configuration before the check! You can now exit the HW Config. You are prompted whether you want to save the changes. Respond with NO! This way you can discard all changes that are not CiR-compatible. General Recommendation After a successful download, make small changes to the HW Config and note or remember the changes you have made. Should the result of the CiR check be negative, there is no major loss when you discard the changes. If, however, the changes are necessary, you will have to resort to downloading with the CPU in STOP mode and then reboot. For a detailed description, please refer to the manual "STEP 7 - Modifying the System During Operation via CiR” that was installed on your ES. The programming instructions in that manual can be disregarded under PCS 7, as the PCS 7 driver blocks take care of the specific cases.

Some properties that are relevant for the CiR are already checked during configuration. In the above example, the address range reserved by the CiR module is not sufficient to allow insertion of another analog module. It is not possible to download changes made to the reserved range in RUN (see next page).

Any subsequent changes to the reserved range for this ET 2Q0M cannot be downloaded in RUN, i.e. if insufficient address space was allocated before the first download. How should we proceed now? If the CiR object on the DP subnet still has sufficient address room for slaves, an additional ET 200M can be inserted there and fitted with modules. In the latter case, you should create sufficient reserve addresses so that the new rack can be completely equipped.

PC Station

The PC can be used as ES or OS or both. It must however be set up once, immediately following installation of PCS 7. Then it can be changed later. C om m issioning Wizard The Commissioning Wizard appears after the installation and detects (via Win2000 functionality) the network cards (CPs) on your computer. You need to make settings for the CPs (explained in more detail later) It is also automatically started if new or different communications cards (CP) were installed on the PC after it was last shut down. Set PC Station

After the Commissioning Wizard has finished, this tool opens and the modules/CPs recognized by the Commissioning Wizard are displayed. For each module, the operating mode is displayed in the "General" tab: "Configured Mode": The CP (module) is loaded from the project by the Hardware Config (configured). The preset configuration created there determines the behavior of the CP (actual configuration). "PG Operation": In this case, the CP is configured via the properties. or via START-> SIMATIC->SIMATIC NET->Settings -> Set PG/PC interface PCS 7 version)

(as you may already be familiar with from the previous

SCE

The Station Configuration Editor is displayed in the form of a table. Only the CPs that are set in "Configured Mode" initially by the "Commissioning Wizard" (or later by "Set PC Station") are entered in the table. If a CP is switched from "PG Operation" mode to "Configured Mode" in the "Set PC Station" tool, it is automatically recorded in the SCE table. When the mode is set back to "PG Operation", the CP is removed from the SCE again.

Remark

Each component (also the individual CP) is assigned an index in the SCE (like a "slot" in the table). You can change the slot/index in the SCE via: Select CP and Edit or by moving it with the mouse.



System Config

You can also delete a CP in the Station Configuration Editor (it is automatically switched to PG Operation) or add one (it is switched to "Configured Mode” again). Software components can also be inserted in the SCE - as substitutes for the applications that are to run on the PC. These include, for example, "Application" to set up connections from this PC to other network stations, "WinCC Application" for the WinCC software to communicate (if the computer is used as an OS). The "Application" also has an index/slot and can be moved if necessary. Note 1

The SCE table can be viewed as a rack whose components have to be loaded from the PCS 7 project. The individual component in the SCE must have the same index as its counterpart in the HW-Config of the project.

Note 2

In SCE there is a bottleneck with regard to the Softnet modules. It is not able to administer two Softnet modules with the same protocol if they are both in "Configured Mode" at the same time. This is the case, for example, if Ethernet communication in PCS 7 is running over BCE and Softnet modules are being used. Remedy: In the "Set PC Interface” tool, set the Ethernet connection for the plant bus in "Configured Mode” , while the terminal bus connection remains in "PG Operation". This means that the systems bus connection in the PCS 7 project is configured in the HW Config of the PC station and is also loaded. The terminal bus connection, however, appears neither in the SCE nor in the HW Config.

Set PC Station.

The "Modules" and "Access points" tabs are of interest for PCS 7. Modules

All communication modules detected by the Commissioning Wizard are listed here.

CP 5611

The CP can be used for interconnection via MPI or PROFIBUS DP. It is set to PG Operation, as it is only used for PCS 7 V6.1 in some specific cases.

CP y (see page 26)

In the example, "Configured Mode" is displayed as the mode type for the internal LAN interface (Intel). Index "4" means that this module was entered in the SCE on "Slot 4". It can be moved there if required. The settings for the module are loaded from the project after the HW Config is opened. The module is required as a connection to the plant bus.

CP x

In the example, "PG Operation" is displayed as the mode type for the 2nd LAN interface (Xircom). This module is not displayed in the SCE, is not used in the HW Config, and is not loaded from the project. The module is used as a connection to the terminal bus.

Remark


To change the operating mode (PG Operation <->Configured Mode) you must have administrator rights under Windows. In Configured Mode, the parameter settings for the module are loaded from the project. In "PG Operation", you set the parameters.

The available access points are listed here. The assigned interface parameter settings and module are displayed for each access point. Applications that use the protocol libraries (DLLs) directly use the name of an access point to access the module. Double-clicking on an access point opens a dialog where you can make changes to the assignment. The access point "S70NLINE" is the relevant access point for online operation of the ES. Which device (interface) the SIMATIC Manager uses to communicate with the ASs is determined by the access point. For example, if S70NLINE is set to CP5611(MPI), the SIMATIC Manager will only try to access the other components via this module with its MPI settings. On the other hand, if the access point S70NLINE is set to "PC internal(local)", the SIMATIC Manager tries to find the path to the other components on the basis of the configured networks. If several paths/gateways are possible, then a screen form will appear offering a selection of the available gateways.

Remark

This setting is also required in order to download the configured ES/OS configuration "to the PC". It is also used for central configuring in large-scale projects (multiprojects).

Exercise (info option) Set up the Station Configuration Editor so that Index 2 (row 2) contains a WinCC application while Index 3 (see slide) contains the Ethernet OP for the plant bus. Enter the Windows name of your PC as the station name. Note 1

The SCE initially only shows the communication modules that the Commissioning Wizard has found that are in "Configured Mode".

Procedure

Start the Station Configuration Editor from the desktop (or alternatively, via the icon in the Windows taskbar). Select the row with the contents you wish to delete, then right-click and select Delete to remove the contents. If it was a CP, it is removed from the Station Configuration Editor, but remains in the Set PC Station tool where it is switched to PG Operation mode. If the correct component was already entered, but in the wrong row, you can move it to the correct row with a drag-and-drop operation. If you want to add a new component, select the row in the table, right-click and select Add. A screen form opens where you can select the component you wish to insert. An application should run on the PC according to its function in the network. If the PC is used as ES, it needs a slot/index of type "Application” or "WinCC application" in the SCE. If the PC is used as OS, it needs a slot/index of type "WinCC application", "WinCC application (stby)" or "WinCC application client" in the SCE. Which option to select depends on whether the OS is configured as a single server or redundant server, or if the OS is used as a terminal (client).

Once the configuration is completed on the PC, it must be loaded from the HW Config (which is contained in the project). Then the PC is ready to assume the role assigned to it (ES or OS) Note

Later when the connection is configured, the application represents the contact point on the PC side for the CPU from the AS side.

Note 2

The previously described procedure also functions in Version 7.0. A disadvantage is the double configuration (once as SCE on the PC and additionally in the hardware configuration of the PC station, in the PCS 7 project). With Version 7.0 and higher, the SCE can be derived from the project once the hardware configuration has been created in the project. Initial creation of the SCE is then omitted.

2. The OS was created as a SIMATIC PC station. The PC station was also configured as a component with the HW Config tool. In the component view of SIMATIC Manager, select the SIMATIC PC station, right-click and select Open Object (or double-click the configuration icon). In the hardware catalog, open the node "SIMATIC PC Station", select the components and use the mouse to drag them onto the PC rack. You need to match the slot in the rack with the Station Configuration Editor (SCE). The matching must take place before downloading the configuration to the PC (see next page).

Components

The components are as follows:

WinCC Application

This corresponds to the OS software. However, the index (slot within the rack) does not match the position in the SCE (Station Configuration Editor). It needs to be adjusted as follows: - Use the mouse to drag the WinCC application to the same position in the HW Config rack as in the previously configured SCE, - Or, the SCE is automatically configured (see next page) if it is still empty. In the latter case, the slot/index in the HW-Config is now irrelevant.

CPs

2. Communications processors for connecting the PC to the networks (MPI, PROFIBUS, Ethernet). In our exercise do not configure CP 5611 as it is running in "PG Operation" and is not loaded. Select the Ethernet CP installed in your ES/OS PC configuration and drag it onto the PC rack. Set the Ethernet address (MAC address) in the CP properties according to the parts list for your workstation. In our example, deactivate the Internet protocol (TCP/IP).



Page 33

System Config

Note

If an IE General CP/Softnet CP is used (e.g. 3Com or LAN onboard), then it is generally not possible to change its address and the address in the HW Config must match the address displayed in the "Set PC Interface" tool.

OS

After you compile or complete the HW-Config with with a Save operation, an OS station is created in the component view of the SIMATIC Manager under the SIMATIC PC station. Select the station, right-click and select Object Properties Then, the station as "OSxx", where xx is the number of your station (e.g. O S O I).

PG/PC interface


Change the S70NLINE interface to "PC internal (local)". While this setting is irrelevant at the moment, you can make it now since you already have the SIMATIC Manager open.

4. You can only download the PC if the access point S70NLINE was set to "PC internal (local)". Set the access point accordingly via Set PC Station. As an alternative, you can also set the access point from the SIMATIC Manager via Options -> Set PG/PC interface Access point S70NLINE -> PC internal (local)

Note 1

Compile from the HW-Config Tool (symbol 1 in the slide). The compilation process can take several minutes (depending on the computer), as a complete WinCC project is generated for the WinCC application.

Load

To download the PC configuration, select symbol 2 (see slide).

Compile

Acknowledge the dialog boxes that appear. If error messages are displayed, this could indicate that the PRESET and ACTUAL states are incongruent. Open the Station Configuration Editor and look at the symbols in the Components tab, Status column. For more information, activate the help button in the Station Configuration Editor. Also check the Diagnostics tab! Have you obtained the SCE through "Configure station"? Note 2

In order to enable all AS and OS of the projects contained in a multiproject to be downloaded from the central ES, the PC interface must remain set to PC internal (local) for the duration of the project. It is necessary, however, to merge the different networks of the projects (make them known). The NetPro tool is used in the multiproject for this purpose. You can also use it to set up the S7 connections required for the online data transfer between the AS and OS. The next pages show you how to merge Ethernet networks and create the S7 connection between AS and OS.

Launch NetPro for both projects (PRO_OS and PRO_AS) and merge the Ethernet subnets there. Then create an S7 connection from the OS to the AS and download the connection to both devices (AS and OS).

Steps

1. Start NetPro for the OS project. 2. Start NetPro for the AS project. For clarity, arrange both side.

windows side by

3. Merge the Ethernet subnets. 4. Create the S7 connection called OS01_AS01 between the and download this to both stations. Procedure

OS and the AS

1. Select the PROMOS project in the SIMATIC Manager. Click the NetPro icon (see slide). NetPro opens with a window displaying the networks from the PRO_OS project. 2. Select the PRO_AS project in the SIMATIC Manager. Click the same NetPro icon. As NetPro is already open, it appears in the foreground again and displays a second window with the networks from the PRO_AS project. Select the menu command Window -> Arrange -> Tile Vertically to display both project-specific networks side by side. At this point they are still independent even if, for example, the Ethernet subnet has the same name in both projects (plant bus, see next slide).

Internally the merged subnets are assigned a common ID (identifier) so that they are available as if they were a uniform subnet. One result of the common ID is that the setting for the access point ''S70NLINE -> PC internal (local)" is sufficient for the SIMATIC Manager to find and suggest a route for loading the devices! You just need to download this new information (e.g. from the HW Config) to the ES first! Then you can download an AS too with the same setting.

Info Flow

Sensors, transducers, and DP process signal converters modules acquire process information. The AS processes this information and uses the same path to pass it on to the actuator. In parallel, commands are sent from the OS to the AS. AS information is displayed graphically on the OS.

ET 200M

The IM 153-2 interface module converts the process signal converter (I/O module) information into message frames for and from the AS.

DP bus

The bus (PROFIBUS DP) transports the message frames between the AS (DP master interface) and the ET 200M interfaces.

AS (S7 417-4)

The DP master interface reads in the message frames in the AS. The driver blocks convert and process the message frames into process values. That is, open-loop control algorithms and closed-loop control algorithms convert the message frames into commands and send the commands back to the I/O using the same path. The values are also monitored, and messages are sent to the OS when defined events occur.

Plant bus

The plant bus can be MPI (Multi-Point-lnterface), PROFIBUS or Industrial Ethernet. The plant bus is used for communication between the AS-OS, AS-AS, as well as between the ES and the above mentioned nodes for the purpose of configuring and commissioning.

OS (WinCC)

Data coming from the AS - embedded in process displays- are displayed graphically as measured values with a time-based sequence and as messages with classification. The plant operator's commands are passed on to the relevant AS and the response information displayed. The configuring and commissioning steps shown on the following pages are structured on this basis.

ES (STEP 7)

The entire project is carried out on the Engineering Station (ES). The software accesses the plant bus via "S70NLINE". Access can be established via different hardware components and is settable. SIMATIC PCS 7 System Training

Each connection is assigned an ID:

Recommendation

•

On the PC (application) side, this ID is a name (e.g. S7_Connection_1)

•

On the AS (CPU) side, the ID is a value.

Change the default name to a meaningful name(e.g. OS01_AS01). This makes it easier to see who the connection partner is in the connection table of an AS (CPU). Moreover, it is advantageous for the online test of a configured OS on the ES-PC (keyword "Start OS Simulation") before the active OS is loaded.

When downloading the connection for the first time, select the stations (AS and PC) you would like to download, then select PLC -> Download to Current Project -> Selected Stations to download the stations.

Notice

This method requires you to stop the CPU/application for a short duration (seconds) and then restart it! The network configuration is downloaded independently of the HW Config download.

Tip

If you do not want the AS to go to STOP (for example, if this is not permissible for the process), use a different method: Select the AS and download by selecting PLC -> Dovsnload to Current Project -> Connections and

The standard view (left window) displays the devices of the individual project only. The subnets are displayed both with their project-specific name and their merged name. You can select the different components and set them via the relevant menus (usually Object Properties).

Cross-Project View This view serves mainly to view information that is relevant at the level of the project (no configuration of the components). For example, from here, you can download the connection data to the listed components. Remark

Each node (CPU or application) has its own, limited connection table. Individual, downloaded connections cannot be deleted online. Should you need to delete them, you first need to delete the connection in the offline table and then download the full table by selecting PLC -> Download to Current Project -> Selected Stations However, as described above, the stations must be set to STOP for a brief duration!

Additional Information When configuring connections, the SIMATIC Manager provides them with IDs in the same sequence as they were created. If both nodes exist in the multiproject, you can select the partner, and each one is automatically assigned a separate ID for this connection. If the partner is not yet available, you can reserve an ID as described in the next section. Connections in Unknown Project To do this, highlight the CPU in your project, the connection table appears, select an empty line, right-click and activate Insert New Connection to start the process. Then select as your Connection Partner: the option "In unknov/n project" and then the Properties of the S7 connection. Under Properties, enter a connection name/reference (circled on the slide) and specify whether the local CPU is to establish the connection (circled on the slide). Only one partner in the connection is permitted to establish an active connection. If the connection has not been closed, it will be displayed as an error when NetPro is terminated, by way of a reminder. Later, when the other projects have been incorporated into the multiproject, connections from the various projects with the same reference are merged when the projects are adjusted. After that point, the address details are known for both stations and the connections can be loaded into both. Note

The project merge can either be started from the multiproject or - like with the subnet merges - in NetPro by activating the menu command Edit -> Merge Connections...

SFC Flow Chart

The chart topology, the action functions of the steps, the switching conditions of the transitions and the runtime properties specify the flowchart created with SFC.

E ditor

Graphics are used to structure the flow chart. Connections with block parameters already present in the CFC charts are used to configure the individual components (steps and transitions). Therefore, there is no programming; instead, you just access templates.

Insert

You can select the structure symbols from the step symbol bar. You click the symbols to insert them (before/after a transition). Steps are always inserted together with the necessary transitions.

Step

Double click the step symbol to begin configuring the step. You must fill out the tabs for this. When configuring actions, you can use the "Browse..." button to display the blocks contained in the CFC charts ("Magnifying glass") and transfer their parameters to the action list.

Transition

Double-click the transition symbol to begin configuring the transition. You must fill out the tabs for this. The same things apply to configuring actions as to configuring steps.

Runtime Properties

The chart will be automatically inserted into the OB where the pointer for the runtime sequence is positioned.

Com pile/Download

Compilation and download are performed in the same way as for CFC. All chart information is maintained in the chart folder. The compilation result is entered in the block folder and downloaded from there to the CPU.

Test The sequencer can be run and tested when the CPU is connected and test mode is selected (Test menu). Double-click the step/transition symbol to display the current states.

A ctions

Actions that determine what steps must do in the process (such as specify parameters and trigger switching operations) must be configured within the step. You can enter up to 50 actions per step section.

Step

A step consists of actions that run in three sections:

Initialization

Initialization is carried out once (for one program run from the OB) when the step becomes active.

Processing

This section is carried out for every run from the OB until the next transition is fulfilled. If the transition is fulfilled, the terminating section (see below) is carried out during the next OB run of the sequence.

Term ination

This section is carried out once, after the next transition is fulfilled. After the last command, the step becomes inactive and simultaneously, the following step becomes active (with its initialization), depending on the topology.

Transitions

Transitions contain the step enabling conditions for the next step in the sequence. You can evaluate the validity of up to 16 conditions using five logical gates. If you mouse-click the gate or connecting line, you can convert it to AND, NAND, OR or NOR.

SFC Sequencers

When created, an SFC chart has a sequencer (called RUN). It can be extended to include other sequencers (which can be inserted, moved or deleted in the chart in the lower bar using the right mouse button). After insertion, the sequencer can be displayed by clicking the associated tab.

Start Conditions

A logic can be constructed in the sequencer properties same as for with the transition. In this tab, you can define the conditions for the SFC chart/type that are to start the sequencer (e.g. "SFCName.RUN = Active” starts the sequencer if the SFC chart is in "Active'1mode). At any one time there is always a maximum of ONE sequencer being processed (active) in an SFC chart. If the start conditions are fulfilled for several sequencers, the "Priority” property decides which sequencer is executed (1 is the lowest and 255 the highest priority). If sequencers with start conditions that are fulfilled at the same time also have the same priority, the sequencer which is located further to the left is initiated first.

Preprocessing

In this tab, you can define the actions for the SFC chart or type that must be carried out before each sequencer processing call (regardless of whether the respective current step is in initialization, processing or finishing). Each line constitutes one statement. Up to 50 statements are possible in each case. You can change the selection of displayed statements (10) using the vertical scroll bar at the right-hand side.

Postprocessing

In this tab, you can define the actions for the SFC chart or type that must be carried out after each sequencer processing call. Here, too, up to 50 statements are permitted. The preprocessing and postprocessing tabs are actuated before and after each sequencer cycle, as long as the sequencer is active.

Run sequence

The recommended rule here is: the SFC is called after the blocks that it queries in the transitions, but before the blocks that it writes with commands (to the extent possible).

Remark

You will first create an SFC chart with one sequencer. Then, after more information is provided, you will add additional sequencers to the SFC chart.

Following the download operation to the CPU, the sequential control system is in a defined state. This defined state is specified with the SFC Editor (default: Ready). Now the sequential control can begin either automatically (SFC Chart Properties -> Start Options -> Autostart) or after a start command (menu Chart -> Properties -> Start Options -> Operating Parameters).

Sequencer O perating State L o g ic (OSL) Processing of the sequencers is controlled by the sequencer operating state logic. The sequencer's operating state logic is defined in the diagram of the state transitions for sequencer OSL. Operator Commands You can use commands to change the sequential control system between states (e.g. Start, Hold, Resume, Abort, Complete). Step Control Modes

The different step control modes modify the behavior of prepared or fulfilled transitions. A change in the step control modes is possible in all of the operating states. The individual step control modes mutually exclude each other. The following step control modes are available: T T or O

AS solution

SITRAIN Trainings AutonraGon and Drives

The block libraries contain different blocks that form individual parts of the solution. Drivers, operator control blocks and technological blocks (closed-loop controllers, motors) are used.

Inputting/outputting process signals The single-channel drivers (CH_AI, CH_AO, CH_DI and CH_DO) are located in the PCS 7 library. These drivers are inserted in the CFC in which the process value is needed. The symbolic name of the value is used to select the connection to the process value (via the symbol table). The name is assigned to the individual hardware channel during the hardware configuration. No additional parameters must be set, except for the measuring range. After CPU selection, the CFC generates the necessary module drivers during compilation, along with all of the necessary parameter settings (which are read from HW Config). With V7.0 and higher, the CFC also inserts the CPU_RT block, which can carry out runtime measurements and avoid a CPU stop in the event of an overload. Remark

With V5.2 and higher, you can also use universal drivers (CH_U_AI, CH_U_AO, CH_U_DI and CH_U_DO). They can be used for S7-400, ET 200M or Profibus PA field devices. If you want to configure an older CPU (from V4) using PCS 7 V6.0, you must continue to use the V4 libraries, or the CPU will be upgraded.

Temperature control

You can implement temperature control, for example, by using the CTRL_PID block from the same library. This block also has the faceplate necessary for operator control and monitoring (for WinCC).

Signaling

You can use the MEAS MON block, for example, for this. This block monitors the level and signals a limit violation to the OS. The controller block itself can also monitor its own process variable and signal limit violations to the OS.

Exercise

Create a setpoint control for the temperature controller of reactor A (see slide). If specific process values are not reached or are exceeded, the setpoint must be set to defined values.

Steps

1. Create the SFC chart "SFC_Temp" in the same folder containing the CFC chart for the temperature controller. 2. First create the layout of the sequencer as per the above illustration, with the prescribed names for the steps and transitions. 3. Then configure the steps and transitions. 4. Next, compile ("Changes") and download ("Changes") the program. 5. Test the sequence in test mode.

Procedure

Procedure for configuring the steps:

C onfigure steps

Select a step from the sequencer and open it by double-clicking. In the "General" tab, enter the name, min. and max. runtime, the step comment in the control, the step comment in the visualization, and acknowledgment information (if leaving the step has to be acknowledged). The "Initialization", "Processing" and "Termination" tabs must be used to configure the actions in this step. Go to the "Processing" tab, place the cursor in the first free line, and click the "Browse" button (at the bottom of the screen) to look the charts in either the "Plant view" or "Component view" tab until you reach the controller block. Select this block and select the required parameter in the right pane, e.g. The SP_EXT parameter from the CTRL_PID block for the reactor heating control.



Page 7


You now have to assign a value to the selected parameter in your statement (to the right of := ). Enter the temperature value, e.g. 70.0, in accordance with the function of the step. C onfigure transition Select a transition from the sequencer and open it by double-clicking. In the "General'' tab, enter the name, the comment (ES), the OS comment and the acknowledgment information. The "Condition" tab is used to configure individual conditions within the step enabling condition. Here too you can use "Browse" to select the required parameter from the CFC charts and then use the symbols =, <>, =>, =<• >, < to compare it with a specific value or another parameter, e.g. P V J N from CTRL_PiD < 33.0 (degrees) Com pile and Download The program is compiled and downloaded (as described in detail in the CFC section) from the SFC chart using the same procedure as for the CFC. Compile and download the changes. The compile and download operation always applies to all CFC and SFC charts in the program to which the SFC chart belongs, i.e. from where you are initiating the procedure (they form a common program). Testing the SFC

Test mode is enabled and disabled using the command Debug -> Test Mode Compared to edit mode, the SFC chart window in test mode is expanded to show an operating and display section at the bottom of the window. In addition to selection of the operating mode (MANUAL, AUTO); you can also see the following buttons for the SFC: - Start - Abort - Restart

- Hold - Complete - Reset

- Resume - Stop - Error (handling)

When the steps and transitions are cycled through, they will display different colors depending on their state: Step active

Exercise

The sequence for the manufacturing procedure in Reactor A was described in the "Configuration Overview” tab, page 2. Now implement this sequence using an SFC chart. Configure, compile, download and test this SFC chart.

Requirement

You have implemented and tested the example in the chart "Exer_Reaci" with the MOTOR, VALVE and CTRL_PID blocks.

Steps

1. In the plant hierarchy under "Reactors\UnitA", create an SFC chart, "SFC.ReacA”. 2. Establish the sequence of the SFC (see picture above). 3. Configure the actions in the individual steps and the signals to be queried in the transitions. 4. Compile and download the program. 5. Test the project.

Procedure

You can derive the sequence from the above picture. Control the filling valves and the drain valve using the VALVE blocks. Control the mixer via the MOTOR block. For the "heating” step, set the controller to AUTOMATIC and the external setpoint to 90°C. You can include waiting times by inserting an empty step (with a minimum runtime setting) and an empty transition.

SITRAIN Training for Automaton and Drives

For the SFC to be able to pass its commands to the valves or motors via the above listed blocks, it must be able to influence the blocks' operating mode (set the operating mode to AUTOMATIC) and write commands to the suitable inputs. It must also be possible for the plant operator to intervene manually when the control has finished. This means the control must relinquish its control over the blocks again.

Operating State Logic fo r SFC State

The current operating state of the SFC OSL can be modified by the following events: - Commands (Start, Resume, Hold, etc.) in operating modes "MANUAL" or "AUTO”. - External signals (SFC inputs, commands from another SFC, etc.). - Internal signals (commands from custom sequencers, from test mode or SFC visualization). - Implicit state change.

Operation

If you also want to open/close the valves manually, you can use simple operator control blocks for digital values (OP_D) or the valve blocks (VALVE) with built-in operator control and monitoring.

Plant simulation

You can simulate the plant using the REACTOR block (in a user library).

Sequential control

Use the SFC Editor for this. This editor can only access data that were configured previously, such as with the CFC Editor.

Interaction w ith Basic Autom ation (CFC) The sequential control in the AS is connected to the basic automation via the action and transition functions. A specific runtime behavior is assigned to each SFC. Basic automation using the blocks contained in the CFC charts can have a different runtime behavior than the SFC. You can control an SFC chart using the external view of the SFC chart contained in the CFC chart.The structure of the sequence system makes it possible for the sequential control and the basic automation blocks to run in different cycles, thereby reducing the cyclical load. In the same way, SFCs can be integrated into runtime groups, and can be given a different scan rate or phase offset via these groups. SFC Runtim e O ptions You can set the sequential control behavior in the runtime options. These can be set in the dialog field "SFC Instruction O utput

Properties -> Tab: Operating Parameters CPU” .

On: The actions of active steps will be processed. Off: The actions of active steps will not be processed.

Cyclic Execution

With "Cyclic Execution: On" the program will automatically revert to "Starting" following the "Completed" operating state. With "Cyclic Execution: O f f the program remains in "Completed” state.

Time M onitoring


With "Time Monitoring: On", the active time of the step is continuously compared against the monitoring time after the step is activated (object properties for the step, "General" tab, "Maximum Runtime" option), and a step error is reported if the time is exceeded.

With PCS 7 Version 7.0 and higher there is an additional possibility for setting the behavior following a CPU restart (see arrow in slide). In the previous versions, the SFC was always initialized, and the data valid prior to the stop were lost (this is now the default setting). In the new version, the SFC status can be retained. Following a CPU restart, the SFC then retains its status. Using the SFC and process states, the operator can then decide how the SFC is to continue working.

Exercise

Set the SFC from the previous exercise such that it retains its state following a CPU restart. Test the restart behavior of the SFC (by means of CPU stop followed by a CPU restart) in the "Component X" and "Heat” step. What happens to the configuration due to this behavior? What happens, for example, with the filling of component X in the reactor in the meantime (between the CPU Stop and Resume command by plant operator, once the CPU is running again)?

Steps

1. Open the SFC, select the menu SFC -> Properties

"Operating parameters CPU" tab

and select the ”Retain SFC status” option. 2. Compile and download the changes. 3. Switch on test mode, and start the SFC. 4. When the "Component X" step is reached in the SFC, stop the CPU (using PLC -> Operating Mode^> Stop). What is output by the output modules to which the valves (simulation) are connected? What does this mean for a real plant? 5. From the last screen form, carry out the CPU restart. You must then decide at some time whether the SFC is to continue or stop/abort. A new command is not output by the SFC up to this point. What commands are output by the valve, motor and controller blocks? Note that the blocks mentioned also exhibit a restart behavior when the CPU is restarted, but they then call their program cyclically in the cyclic interrupt OB with the parameters which they find there.

The SFC chart has a standard interface through which it can be controlled using CFC interconnections. This interface Is represented as a graphic "external v ie V of the chart. Activate the following menu command in the SFC View -> External View to open the CFC with an external view window.

Representation

The external view shows the SFC as a block with an SFC chart symbol in the block header. The block name is the SFC chart name and cannot be changed.

Interconnection

Inputs can be interconnected to other objects, global addresses or textual interconnections. Please refer to the online help for more information about the individual parameters (Help on SFC External View... See also... Standard interface for SFC charts). There the parameters are listed both alphabetically and according to their use. You cannot add further objects to the CFC chart showing the external view of the SFC. All interconnections must pass over the edge of this chart.

Tip

Open the external view of the SFC (= a CFC window) and the CFC chart from which the control is to be influenced (= a second CFC window). Arrange both windows side by side. Interconnect the blocks as described in the CFC chapter.

Date. 07.12.2006 R q:ST.PCS7SYS_V70 SfC.18

Supplement the sequential control for Reactor A as follows: If the plant operator issues a hold command for the SFC control, a second "HOLD sequencer" will start up. This is to ensure that valves V1, V2 and V3 close, the mixer is switched off and the temperature controller is set to manual operation with a preset manual value. The HOLD operating state must not be reached until the two above-mentioned commands have become effective. This state must be saved in a DB. The operator can perform operations in the HOLD state. If the control is to exit the "HOLD” state, the valves, mixer and controller must be switched back to the state saved in the DB, i.e. the state they were in when the HOLD command was issued. This is achieved by using a third "CONTINUE sequencer" which resets the blocks to the desired state and is only exited after a check has been performed.

Steps

1. Insert additional sequencers in the SFC_ReacA. 2. Set the chart properties for the two additional sequencers. 3. Create data block to save data when control is in HOLD state. 4. In SFC_ReacA complete programming of the "HOLD" and "CONTINUE" sequencers.

Procedure

1. Insert two additional sequencers in SFC_ReacA. With the SFC open, go to the "RUN" tab (below), right-click and select Insert Sequence at End to insert another sequencer. One SFC can process up to eight sequencers in alternation. With the SFC open, set the chart properties via Chart -> Properties as follows:

Create Data Block Create a data block (DB) (e.g., DB1 with a symbolic name, "ReacA_DB"). This block is to be used to save the necessary states when the main sequencer is held (see above for possible structure). To do this, you need to switch to the project component view. Select the block folder, then right-click and select New Object...-> Data Block to create the global DB1. Enter the symbolic name "ReacA_DBr' in the Properties window. Then select the block, right-click and select Open

to start the data block editor (see above).

Define the necessary parameters in the corresponding data formats. Configuring SFC with Two Additional Sequencers Configure the HOLDING SFC and the RESUMING SFC. HOLDING SFC

This is started when a command is received to hold the RUN SFC.

"Save" Step

In the "Save" step, the relevant pending commands/data are saved in DB1 (see above, content of DB1) and then the desired settings are made.

T ransition

This checks whether the operating modes and values that were set as a precautionary measure have become effective. The sequencer is completed only after the transition is fulfilled. The SFC chart then changes to HOLD state.

RESUMING SFC

This is started when a command is received to resume the RUN SFC.

"Restore" Step

The "Restore" step is the opposite to the "Save" step in the HOLDING sequencer, i.e. the data is read from DB1 and distributed across the relevant block parameters/inputs (from right to left).

T ransition

This checks whether the saved states have become effective again before the RUN sequencer resumes activity.

SFC Type

In SFC V6.1 there is an SFC type in addition to the SFC chart. This makes it possible to define sequential controls, including an interface. The runtime logic of the SFC type is based on the interface of the SFC type, i.e. the SFC type cannot access just any process signals. Like function blocks, SFC types must be placed on a CFC chart, where they are given an SFC instance.

Creating an SFC Type SFC types cannot be inserted into the plant hierarchy, since they cannot run on their own. Instead, they are created using Insert new object -> SFC type in the component view in the SIMATIC Manager or SFC -> New (select "SFC type" in the "Object type" field) in the SFC editor. Manipulating the SFC Type The SFC type is a m anipulate object like the SFC chart; however, it has its own symbol to distinguish it from the latter. The attributes necessary for the SFC type (e.g. S7_m_c) are preset. Seven messages requiring acknowledgement and five that do not require acknowledgement can be configured for each SFC type. The other available messages are required by the SFC type itself. Configuring Using the SFC Type Only the interfaces for the SFC type can be used to configure actions in the steps and the start and step enabling conditions. In other words, external access is via the SFC type interface only.

SFC Instance

If an SFC type is used, it is inserted into a CFC chart. An SFC instance will be assigned to it at this point. SFC instances are therefore always assigned to the CFC chart and are addressed via the chart. By assigning the CFC chart to the plant hierarchy, the instances that it contains are also indirectly assigned to the plant hierarchy.

Messages

SFC instance messages can be configured in the SFC via SFC -> Message or in the CFC in the object properties dialog box. The messages are PCS-7compliant and can also be provided with associated values, for instance.

Configuration

When you configure SFC instances, the interface and the sequencers must not be changed, as they are specified identically for all instances through the SFC type. Changes that are made directly to the instances may be loaded at any time, even if the SFC instance is currently being processed in the automation system. After you have configured any changes, you must use the function OS -> Compile to ensure that the current data are also available on the OS.

Compile

If the program is compiled on the ES side, the SFC instances will be compiled along with them. For any given SFC instance, 1+n data blocks will be created (where n = number of sequencers within an SFC).

Introduction

The steps described below are a simplified representation. For more detailed information about the sequences and what needs to be taken into account at the outset, please refer to the "PCS 7 - Engineering System Configuration Manual", Chapter 3 "Planning the Plant Engineering".

Block libraries

The libraries that are not used should be hidden via the SIMATIC Manager file management function. It can be advantageous to create a separate library for each project in the same project directory (master data library). To start, the blocks that will be used later in the project are collected there. If in the future the software is upgraded, this library can be updated across all subprojects.

Create project

Use the SIMATIC Manager to create the new project. The Manager handles all of the data generated during configuration.

Resources

Resources include the ASs in the project (with their hardware), the S7 programs (with blocks in the user program and with chart containers and the blocks imported to these chart containers via CFC), networks, as well as the ES/OS PCs.

Hardware

Within the project, the AS/PC hardware components (CPU, CP, and I/O modules) must be configured in accordance with the hardware structure. This configuration is downloaded to the AS and assigns the parameters for the modules.

Plant hierarchy

(PH)

Assign resources

A hierarchy (with a maximum of eight levels) is used to display the configured plant in the project. This hierarchy can correspond to the HID system (comparable to a directory tree). One AS and/or one OS can be assigned to each hierarchy level. The subordinate levels can inherit the assignment. CFC/SFC charts, OS displays, reports or documents belonging to the assigned AS/OS can be inserted in each level (as "leaves" on the "branch").

Software

AS-specific or OS-specific tools are used to configure the software as needed. From the AS, you open the object in the plant hierarchy to start the software.

Test + Commission

The software must be loaded onto the configured hardware for this. Each configuration tool you use provides testing opportunities for online operation.

The OS is created as a SIMATIC PC. The PC is also set up using the HW Config tool (like an AS). The basic data for a PCS 7 OS are configured using the project editor (within WinCC). Individual objects are inserted via the plant hierarchy or process object view and then completed in the appropriate editors (of WinCC). The OS must also be compiled and downloaded (like an AS). The OS PC must be networked with the ES PC for the download to work. You can find details about this in the section "HMl/Operator Control and Monitoring".

We shall repeat the project environment as in the previous chapter in order to create a suitable project structure for it. We will take into account the plant structure for this, while also considering the specific AS and PC equipment available in the training room.

Project environm ent

Our project is part of a dye manufacturing plant. The basic materials are manufactured in Factory 1 and are transported from there to Factory 2. In Factory 2, the basic materials are stored in dedicated storage tanks. After undergoing the manufacturing process, the end product is stored in a different section of the tank farm for transport purposes.

S IT R A IN Traning for Automation and Drives

A project containing an AS and OS is to be created in such a way that it can be simultaneously edited on different ES systems at a later time. The "multiproject" is the project type of choice for this application. Create a PCS 7 multiproject in which one project is created for the AS side and one for the OS side. In each project, configure the hardware for the devices used (AS or PC) and download the configuration to the devices. 1. Create the multiproject using the SIMATIC Manager. 2. Create the two projects in the multiproject (one project for the AS, the other project for the OS). 3. Set the language for the display devices (in which language the plant operator will read his textual information). 4. Configure the hardware used in each of the projects. 5. Compile and download the configurations to the devices.

Remark

Steps 4 and 5 can also be performed after the entire configuration has been completed, at the latest before debugging and startup. As we want to test online as soon as possible, we will carry out these steps even before creatinq the software.

Procedure

1.1 Start the SIMATIC Manager by clicking the icon on the desktop or by selecting the following in the task bar: STAR T-> SIMATIC -> SIMATIC Manager 1.2 Select File -> New In the "Multiprojects" tab, specify the storage location and enter a name for the multiproject (e.g., storage location = "PCS7courses_V61" directory on the data drive, and name = "DYE").

3.1 First, select the AS project, and then select Options -> Language for Display Devices If you have not already specified the message number concept in the SIMATIC Manager, you will be prompted to do so. Select the default setting (for V6). This query is necessary as the subsequent language selection will affect the message texts offered during configuration. 3.2 Provided you only want to use German, all you have to do is set it as the default language. If you want the project to be available in multiple languages, it is advisable to set the default language to English (USA). Provision is also made for French, Italian and Spanish in PCS 7 libraries and in WinCC. You can easily add these languages to the "installed languages”. If you want to use the project in a different language (other than German, English, French, Italian, or Spanish), we recommend setting English as the default language (i.e., do not enter any additional languages in the "Installed Languages in Project" box) and installing the required language in WinCC later (this is explained in detail for the OS project). The English texts found there (in WinCC) can be exported, translated and reimported. Remark

The language setting must be made for each project within the multiproject! The project language displayed in the properties of the project corresponds to the Windows language when the project was created, and cannot be subsequently changed. For steps 4 and 5 m entioned at the beginning, please refer to Chapter 4 "S ystem C onfiguration". As these steps do not have to be perform ed but, rather, can be perform ed later, they have been included elsewhere, as indicated. Now we w ill return to con fig uring the system .

S IT R A IN Training k r Automaton and Dr.ves

You have carried out the system configuration. The automation and HMI stations are in the foreground. The plant presented at the beginning of the chapter is to be reflected in the project in a so-called "Plant view" (also known as Plant Hierarchy). The AS ("ASxx") you configured a little while ago will be used to automate the two structurally identical "A" and "B" reactors, the OS ("OSxx)" you configured will be used for operator control and monitoring.

Plant hierarchy You can call a plant-related view (through PCS7) in the project (in the SIMATIC Manager). View -> Plant View This view is initially empty. Select the project name, then right-click and select New Object -> Hierarchy Folder You can then rename the new folders. After selecting a hierarchy folder, you can structure the secondary plant hierarchy in the same manner. Result: The plant view mirrors the structure of the plant. In our exercise we will create a PH with 4 levels. We will use Level 1 as the factory designation. This level is present for overview purposes only as the plant is large; it is not used in the AS and/or OS (nor is it part of the Higher Level Item Designation - HID) It is included in a printout of documentation.



Page 7

Project structure

We will use Level 2 to divide the factory into plants, such as reactors, tank farms, etc. We will use Level 3 for the units (e.g. as Unit A, Unit C or Reactor A, Reactor C) Level 4 will describe the function (e.g., temperature control or inflow) AS/OS assignment

The plant folders must each be assigned to one AS and/or one OS so that the automation task runs in the correct AS (the one that is "wired directly" to the plant) and the monitoring objects (pictures) are created in the correct OS. Select a hierarchy folder, then right-click and select Object Properties - AS-OS Assignment. If you select the "Lower-level objects..." check box, the lower-level directories will also inherit the assignment.

AS

When the AS is assigned, its chart folder is recorded (containing all CFC and SFC charts that run on the assigned AS). Select the AS CASxx")

Note 1:

The reason for assignment to the chart container and not to the CPU is as follows: If you have not yet specified the hardware, you can insert an S7 program (software only) into the project. You can assign the program's chart folder to the Plant View. After you specify the hardware, you can cut and paste this S7 program into the CPU, which is now known. It replaces the (still empty) S7 program of this CPU configured using HW-Config. The already configured plant hierarchy and software also migrate.

OS

Select the OS ("OSxx"). The pictures configured later in the hierarchy folder are kept in this OS.

Name the tasks

Select a hierarchy folder, then right-click and select New Object -> (CFC, SFC, pictures, e tc.) to insert and name the relevant objects. These objects are implicitly inserted in the assigned AS (chart folder) or OS, where the objects are also loaded and must be executed.

Note 2:

PH assignments can only refer to devices (AS/OS) that are located in the same project. However, identical names of the PH in different projects of a multiproject refer to the same plant component to be configured within the multiproject.

Exercise

For the entire multiproject, set the plant hierarchy so that level 2 is defined as the OS area, levels 2, 3 and 4 are part of the higher-order item designation, and the picture hierarchy and diagnostics screens are derived from the plant hierarchy.

Note

For instructional purposes, we will deactivate the "Diagnostics screens..." option again after checking the automatically generated structure. At the end of the second week of training, when we have completed the automation and HMI exercises, we will activate this option again and take a look at the end result.

Steps

1. Select the multiproject and open the settings screen. 2. Select the project that is to serve as the template for the PH. 3. Define the OS that is to be used as a maintenance station (MS), i.e., your ES/OS. 4. Check the changes that have been made.

Procedure

1. In the SIMATIC Manager open the plant view of the multiproject and select the name of the multiproject. To open the screen form, right-click and select

Plant Hierarchy -> Settings

Then set the options according to the requirements for the exercise. 2. In the next screen, select the AS project as the template. (The goal is to avoid having to create the PH again for each project if the selected project already contains a PH.)

3.

Define your OS (ES) as a maintenance station.

4.

After confirming prompts, an operation is triggered, which performs the following actions:

Remark

•

A first hierarchy folder is created in all projects included in the multiproject (e.g. "Plant(1)") which you can expand or adapt for each project as required.

•

A second hierarchy folder is created in all projects included in the multiproject for diagnostic purposes (e.g. "Diagnostics’’). It is later automatically adapted after the software is used to access the hardware.

In the slide above you can see the different breakdown of the diagnostic hierarchy in the two projects. While in the AS project only AS objects contribute to the diagnostics, the OS project contains folders for the AS, network and PC objects (full instrumentation and control setup). The maintenance station that is running on the OS must provide the entire instrumentation and control diagnostics. Whereas CFC charts with diagnostics drivers are created in the diagnostics folder of the AS project (the hardware-related software must run in the AS), pictures are created in the OS project and are displayed with graphic symbols when appropriate. The user accesses the OS diagnostics information for the status of the device via these symbols. The symbols are generated by the PCS 7 MS software.

S IT R A IN Trarang foe Automation and Drrvos

Create the hierarchy tree from the above slide in the PRO_AS project in the plant view. Update the PH in the multiproject to avoid having to make the entries again in the OS project.

Action

In the plant view, click the multiproject, right-click and select

Plant Hierarchy

Update in Multiproject

to open the update screen. The option selected in the above slide will create the PH folders with identical names in all projects A identically-named PH folder in the projects represents the (identically named) assigned plant section. The second option enables limited updating of selected projects. This is necessary, for example, if different plant sections are to be monitored on OSs in different projects. Different plant hierarchies are required in that case. Remark

If you would like to rename the PH folder later, do this in the template project. Folders that were generated through an update will be automatically renamed.

The settings are taken from screen "1" for each hierarchy level of the current project. You can set the naming conventions for your project (number of levels, name length per level, whether the name of the level is added to the hierarchy identification and whether the screen hierarchy in the OS or the diagnostic pictures are derived fromthis plant view). With the OS area, you specify which hierarchy level is applicable as the OS area level. You have set level 2 (see circular mark).

Note:

When you assign a name, note that the process tag name on the OS must not exceed 128 characters. The name is a combination of the names of the folders in the hierarchy path, the chart name, the block name, the separator, and the connection name (parameter name of the block).

Hierarchy folder - Properties After selecting a plant hierarchy (usually in level 1), right-click and select Object Properties to set the properties.

AS/OS Assignment

S IT R A IN Traning for Fie: ST-PCS7SYS_V70_p_stru.13^ Automationand

Select the following in the AS/OS Assignment tab (see above): •

The AS (its CPU chart folder) in which the CFC and SFCcharts are stored.

•

The OS in which the pictures and reports are stored.

This assignment can be passed on to the lower level hierarchy folders, unless other assignments are necessary in lower levels. Remark

HMI Attributes

You can only assign those ASs or OSs that are located in the same project as the PH folder that is currently being assigned. The OS area ID for the hierarchy folder of the level selected as the OS area is displayed in the Control and Monitoring Attributes tab. The ID is preset with the name of the PH folder for this level. The area ID is passed on to (i.e. inherited by) all of the lower level hierarchy folders, OS pictures, OS reports and messages. This means that all lower-level hierarchy folders with their pictures belong to one plant area in the OS. This affects the area-specific authorizations for operating personnel. If the picture hierarchy is to be based on the plant hierarchy, the "Order..." button and the "Picture name for OS" field are active ("Picture name for OS" only if the OS area ID is not active). The name of the hierarchy folder is entered as the default setting for the picture name. The operator sees this name displayed in the WinCC picture hierarchy.

Remark

All of the settings are associated with the AS/OS that you have assigned.

Aulomalion and Dri\'05

The Higher-level ItemDesignation (HID) is formed from the following components: a. Path name from the plant hierarchy b. Chart name c. Block name Whereas the string the plant view contributes to the HID is the result of linking selectable combinations of the hierarchy folder names (components 1 to 4 in the slide), the chart name (5) and block name (6) are always present in the HID.

Process tag

If individual parameters of the module are to be visualized in WinCC, the parameter name (7) is appended behind the previously described components, separated by a period.

Examples In CFC

In the chart reference data of CFC, block 2U301 is displayed as part of Factory2\Reactors\UnltC\Drain\\Dr301. The chart name is separated from the hierarchy path by "\Y\

In WinCC (HID)

The name of the block is displayed as Factory2/Reactors/UnitC/Drain/Dr301/2U301 (if all PH levels contribute to the HID). In our example, "Do not include in HID" was selected for Level 1 in the PH settings. Therefore, the resulting HID for the same block: Reactors/UnitC/Drain/Dr301/2U301

In WinCC (process tag) If a parameter of the above block is addressed, it is identified as a process tag and displayed in WinCC as follows: Reactors/UnitC/Drain/Dr301/2U301.QCONTROL

S IT R A IN Trainingfof Automation aod Drr/es

You can derive this OS picture hierarchy from the plant view. You must use the plant view to insert the pictures for the relevant plant component in the hierarchy folders and provide them with meaningful names . You can then use OS (Graphics Designer) tools to configure these pictures. Tip:

The following method is more efficient: - Start by inserting and renaming only one picture in the PH. - Open this picture in the Graphics Designer (WinCC) and change to the desired dimensions (height, width) there using its properties. - Copy this modified picture (which is still empty) in the PH, and then insert it into the various PH folders.

Project name

Was entered via the SIMATIC Manager. Can still be changed (especially if the projects are to be subsequently combined in a multiproject). The storage location on the hard disk remains the same.

AS name

The SIMATIC 400 station should be renamed so it can be found again at the location of installation. Select the station, then right-click and select Rename

and

enter a new name (ASxx, where xx is your station number). S7 program name

The name of the directory where the software is stored; this directory is displayed as a substitute for the AS name in the process control messages of this AS in WinCC. It should be similar or identical to the AS name e.g. S7_AS03.

Computer name

A PC station is identified via the computer's Windows name. The name is assigned by the computer administrator. To determine the name, select the My Computer icon on the PC desktop, then right-click and select Properties -> Computer Name Then, copy the indicated name. When renaming the PC station in the SIMATIC Manager, you can then insert this name there (do not use special characters in the name!).

OS name

This name can be freely assigned, but should allow the OS function to be identified (SERV2, ARSRV, CL12 etc.).

S7 program name

The S7 program directory can also be renamed for the library.

C onfiguration

A PCS 7 environment consists of ASs (S7 components with suitable I/O), PCs used as an ES or OS and networks between these components. There is an actual configuration and a preset configuration for each component. In addition communication connections must be set up between the stations.

Actual configuration

With an AS, this is determined by the specific structure of the available hardware (rack, power supply, CPU etc.). In our case, the hardware was provided in our training room. With a PC (used as ES or OS), a virtual structure is created using SIMATIC tools for the workstation configuration (Set PC station, or Station C onfiguration Editor). You need to set up the structure yourself (this is generally done when the PCS 7 software is installed on the PC). With V7.0 and higher, this can be simply carried out from the central ES (C onfigure Station).


The preset configuration is created in the SIMATIC Manager within a project on the ES by using the HW-Config tool in the project. It contains project-specific parameter settings for the devices used. After completion, the preset configuration must then be transferred via the network from the ES to the respective station (AS or PC). In doing so, the load procedure must find the components of the preset configuration in the actual configuration.

Connection

NetPro is used for this. Connections are created between: ES-AS, OS-AS, AS-AS (if the latter need to exchange data among themselves). You also need to download these connections to the respective stations.

Remark

All tools are integrated in the ES software and can either be called directly or in the context of the components to be configured.

Configuration

Hardware components are used within the project. These include the automation systems (AS), PCs as operator stations (OS) or engineering stations (ES), and the networks.

Components

In the multiproject, select the required project, then right-click and select select Insert New Object and then as required: •

"SIMATIC 400 Station" for an AS

•

"SIMATIC PC Station" for an ES or OS

• "Industrial Ethernet" for the plant bus or terminal bus,etc. When you select the object to insert, a symbol is generated to represent each device and serves as access point to the configuration. HW Config

The "Hardware Configuration" tool or "HW Config" for short is used for this. HWConfig is used in the same way for both AS and ES.

AS

To configure the AS, use the mouse to select the symbol representing the required AS in the SIMATIC Manager (component view), then right-click and select Open Object The tool is launched. As an alternative, you can also double-click the hardware symbol in the right pane.

ES

To configure the ES, use the mouse to select the symbol representing the required PC in the SIMATIC Manager (component view), then right-click and select Open Object The tool is launched. As an alternative, you can also double-click the configuration symbol in the right pane of the SIMATIC Manager.

To start, the configuration should reproduce the configuration of the devices. The example in the slide shows an AS configuration. The components shown here offer settings screens (usually accessible via the object properties). If the configuring engineer is knowledgeable about the options available and application at hand, he or she can optimize the components’ settings offline first. Then these settings need to be supplied to the devices (by online download to the target systems).

Using HW Config You have created one project with an AS and one with an OS. The hardware configuration must be adapted to the AS and OS you are using. In doing so, the parts lists for the ASs and PCs in use must be taken into account. Terms

Tip

Pasting

The HW Config tool refers to a station (AS o r PC). In the right pane, a tree structure displays the SIMATIC components (hardware catalog). After selecting a com ponent (arrow 2 in the slide), the associated Order No. and a brief description are displayed in the com m ent field (arrow 3). If you have not been able to locate the module (as it is not a current PCS 7 module or is an older module) select the "Standard" hardware profile (arrow 1 in the slide) and search again. There you will find all S7 modules that are known in the current version of the SIMATIC Managers. If you know part of the order number or designation, you can enter it in the Find box and click the button (arrow 4) to find the module. The search is only conducted for the selected profile. Please note that the part designation can occur multiple times! (If this is the case, continue the search.) In the SIMATIC Manager select the station/AS in component view, then right-click and select Open to open the HW Config.



System Config

Then proceed as follows: • Search in the catalog and check the order number and if necessary the firmware version of the racks, power supply, and CPU in use (arrow 3). • Use a drag-and-drop operation to insert the located modules in the left window. • Select the module in the left screen, then -right-click and select Object Properties... then set the parameters for the module. Replace

To replace a rack (or a module inserted in the rack) search for the new, required module in the hardware catalog. Take the hardware profile setting into account when doing so. The comment field (arrow 3) displays the corresponding order number and brief description for the selected component (arrow 2). Select the correct component, "drag” it with depressed left mouse button across to the rack/module symbol and drop it there. If the exchange is possible, a message is displayed with the order numbers of the two components and must be acknowledged. If the exchange is not possible (because the old/new components are not compatible), the mouse pointer will change to a crossed circle. In this case, the settings of the old module should be documented before deleting the module and replacing it with a new one. Then transfer the settings as appropriate or make new settings.

Note

If you have selected an incorrect slot, you can drag the module to another location with the mouse. The new location must be free and wide enough (i.e. correspond to the number of slots required by the module to be displaced).

Remark

The catalog profile (arrow 1 in the slide) was set up with the PCS 7 installation. You can edit the profile (s7hpro0) that is automatically created by selecting Options -> Edit Catalog Profile Here you use the familiar Windows procedure to copy objects from the standard profile (one window) to the new profile (the other window). After completion, the new profile can be saved via Profile -> Save as... The newly created profile is offered for selection in the profile box.

Exercise

Configure the modules for the central part of your AS. Use the parts list for vour AS as your guide! (The example refers to the "Saarbriicken" training room in the Mannheim Training Center.)

Steps

1. Insert the rack (UR=Universal Rack) 2. Insert the power supply (PS=Power Supply) 3. Insert the CPU or supplement the integrated DP interface. Rename the DP subnet and check properties 4. Insert and set CP for PROFIBUS DP (if available) Register CP 443-5 Ext as DP master Rename the DP subnet and check properties 5. Insert and set CP for Ethernet Create a new Ethernet network for the plant bus and rename it Assign or verify MAC address, disable TCP/IP protocol

Procedure Open HW Config

In the project, select the ASxx to be configured (your AS), and right-click and select Open object Use the hardware catalog to locate and configure the components (rack, PS, CPU, CP and I/O modules) in the HW Config for the station. If you cannot see the catalog, select View -> Catalog to activate it.



System Config

Rack

In the hardware catalog select the desired rack SIMA TIC 400 -> RACK 400 -> UR1 then use drag & drop to move it to the top left window.

Notice!

For the catalog component you have highlighted, check the detail specifications in the lower catalog window pane (order No. and comment) so you can insert the correct components. It is possible that the CPU will not start up if you insert a component incorrectly! The slots in the rack are listed in rows. You can now populate each slot (you can also use "drag & drop”).

Power supply

Select slot "1". In the hardware catalog, select SIMATIC 400 -> PS 400 -> e.g. PS 407 10A and position it on row 1. This 10 A power supply occupies 2 slots.

CPU

Select the correct CPU from the hardware catalog (for example) SIMATIC 400 -> CPU 400 -> CPU 417-4 -> V3.1 and drag it to the next free row (row 3). The CPU with the integrated DP interface occupies two slots. The Properties screen opens. Select the New button to create a new DP network and enter a meaningful name (e.g. DP_subnet1, or DP_AS01 _int1, or DP_AS01_ext3). In the properties for the selected network check whether the DP protocol and the desired baud rate are set (default 1.5 Mbaud). The image displayed now represents the PROFIBUS DP with the "DP master system (1)" identifier. The ET 200M is later appended to this.

Networking CPU via MPI

This is no longer necessary with Version V6 and higher.

Remark

The new Ethernet CP from 6GK7 443-1EX11-0XE0 V2 supports direct addressing of the card via the known MAC address of the Ethernet CP, therefore, the initial loading via MPI is no longer necessary.

Additional DP subnet

If an additional CP is connected in the rack for another DP subnet (such as the CP 443-5 Ext), this CP must be inserted in the rack in HW Config and be connected with a DP subnet (as the second DP master). In the HW catalog, select: SIMATIC 400->CP 400-> CP 443-5 Ext, select the correct CP and use "drag & drop" to move the CP to the correct rack slot. In the screen overlaid for the PROFIBUS interface for the CP, select NEW to create a new DP network and then rename the network (for example, DP_ Subnet2).



Page 9

System Config

CP as DP master

Highlight the CP 443-5 Ext in the rack, right-click and select Insert DP Master System to name this system as the master for the new subnet. You can use the graphically displayed subnet for additional ET 200M devices or for PROFIBUS PA devices via DP/PA link/coupler modules. If you do not want to configure the CP (no DP hardware is connected, for example), you must disconnect it from the power source (remove it from the rack). If it is present in the rack but not in the hardware configuration, the CPU (depending on the firmware version) may not start up (remain in STOP mode) or may not be downloaded. Therefore, if this CP exists in the hardware, it must also be entered in the HW Config.

Ethernet CP

Ethernet is used as the plant bus by default. Insert the CP in the HW Config. In the HW catalog, select SIMATIC 400->CP-400->CP 443-1-> "Concrete CP" and position it in the rack. In the overlaid "Ethernet Interface Properties" screen -> Parameters tab, click the New button Then, create a new Ethernet subnet (if you have not already done so), rename the subnet (e.g., "Plant bus") and select this bus to identify the CP as being networked. Set a unique MAC address in the project, taking into account other nodes physically present on the bus that are not part of this project. It is advisable to use the ISO transport protocol for small networks as it provides higher performance. However, if you want to communicate over more spread-out networks that are connected with routers, use the ISO-on-TCP transport protocol instead. Please note the address-suggestion made in the parts list of your training aulomation_sysl em_and deactivate the IP protocol (clear the check box).

Remark

The hardware configuration is downloaded in a later part of the exercise. Here, the AS is loaded directly via the known MAC address of the Ethernet CP for the first time. For this to work, the access point S70NLINE must be active on an Ethernet-capable CP that is connected to the plant bus. (additional settings are described in the chapter "Configuring the Workstation" under Setting the PC Interface). The download also provides the CPU its parameter settings via the Ethernet CP (therefore the CPU is configured during this procedure). If you change the PC interface to the integrated Ethernet CP (LAN card or CP 1613), you can then download and debug additional data (hardware configuration and subsequent software) over the plant bus.

Then right-click and select Properties to open the screen form above. The CiR object must retain resources for future DP/PA slaves. Each slave requires up to 244 bytes (can also be less, depending on the actual I/O modules). There is also a maximum limit for the number of slaves that can be inserted in the subnet online. 1. The guaranteed number of DP slaves (ET200, DP field devices) must be parameterized in relation to future additions. If no "Extra Settings" are selected, the sum of input and output bytes is automatically displayed. 2. They must be taken into account as sum values for the settings in CPU Properties -> Cycle/Clock Bit Memory tab -> Size o f the process images (for all DP slaves on all subnets). The CPU properties cannot be changed online!

Note

The maximum CiR synchronization time has a default setting of 1000 ms. The time associated with the current configuration is displayed in the properties of the CiR object. The default time and the CiR download process can be influenced in the software. To this end, the system function SFC104 "CiR" can be called in a CFC (from the "Standard Library”). By parameterizing and downloading this, the CiR process can be influenced without stopping the CPU.

S IT R A IN Traring for Automation and Drives

As the selected IM 153-2 supports CiR, a CiR module is offered in the lower part of the window from slot 4. I/O Modules

Take the I/O modules and position them on top of this CiR module in the ET 200M table (as previously for the station, but now with modules from the ET 200M / IM 153-2 directory). This way the CiR module is shifted one place to the right, ready to receive the next I/O module.

Note: Addresses

The CiR m odule reserves an address range for inputs and outputs (the total of which is less than 244 bytes - they can be addressed via the slave). Using the module properties, you should reserve sufficie n t address space for modules to be inserted at a later point in time. If you want to add address space later, you must switch the CPU to Stop mode. For example, if the planned configuration is one ET 200M for 8 modules (the corresponding .bus._m.Qdul.es (hardware) must.be installedjjght fronLthe_slari), and if the initial installation is equipped with 5 Al modules (8-channel), this means that 5x8x2=80 bytes input addresses are used. If you would like to add identical modules to the three remaining slots while the CPU is in Run mode, you will need to have reserved 8x8x2=128 bytes input addresses during the initial setup. 1 word=2 bytes per analog value are required.

Note about m odule replacement When using PCS 7 you can replace modules during operation. Select the ET 200, and right-click and select Object Properties -> Operating Parameters tab Then select the option "Module replacement during operation". The bus modules listed here must be installed in the rack. If you forget to set this

option and.replac.e_a.modula later..d.uringj.untime. a rack.failure jnes.sage.is issued (as if all modules.had failed). The power supply for IM is not configured, but an external 24 V supply is possible.

S IT R A IN Trainingfcr Automation atd Drives

The DP master (CP or integrated DP interface on the CPU) cyclically scans the PROFIBUS DP subnet (circular arrow 1 in the slide). In doing so it passes data to the slaves (e.g. ET 200M for passing to the output modules) and reads back data from the slaves (which acquired them from the input modules). The data are passed through an IM internal buffer. During each cycle, the DP master writes/reads values to/from all its slaves. The buffer content forms an image of the inputs and outputs of the modules. The cycle time is called Ttr = Target rotation tim e and is displayed in the properties of the CiR object, here IM 153. The DP update cycle runs independently of the CPU program, but must be at least as fast as the fastest program that processes the process values. For evaluation in the user programs, the intermediately stored input data from the operating system are copied at a defined point in time from the buffer to a CPU memory area and output data copied from there are written back to the buffer at a different point in time. The programs can then gain read (I) and write (O) access to this "process image" memory area.

Synchronization

This ensures that the programs are working with consistent process data. This means that the operating system must provide for the updating of the process input image and freeze it, before starting the program. After the program has been executed and commands have been written in the process output image, the output image is sent to the DP master. However, as process signals and their associated processing operate at selectable repetition rates (slow/fast processes), it is necessary for their synchronization to match as well.



Page 15

System Config

Process image partition The CPU offers OBs with different speeds in which the user can execute programs. You can assign a process image partition to the OBs In the CPU properties - A ssign PIPs (e.g. OB32<->PIP1, OB35<->PIP2, OBx<->PIPs, where n=1 to 16 is dependent on the CPU). A t the same tim e a suitable PIP m ust be assigned fo r the individual I/O m odules in th e ir properties. Driver blocks are used in the PCS 7 software to input and output process data. These driver blocks m ust run in the same OB th a t updates the PIP o f the scanned I/O module. Note

It is useful when wiring the signals between modules to differentiate between slow and fast signals. A module should be assigned to a PIP that is capable of delivering signals to the software at sufficient speeds such that the fastest connected signal is processed currently. If signals are mixed on the module, this causes slow signals to be read quickly, wasting computing time.

Remember:

If you w ant many, it cannot be fast. If you w ant fast, it cannot be many. The CPU cannot co ntin uo u sly w ork in overload. A fter a program med, but lim ited tim e th is leads to CPU stop!

Exercise

The process image partitions are to be updated on the CPU: PIP " I ” by OB32 and PIP "2" by OB35. The I/O modules (in the example) must be assigned to process image partition "1." Give the individual channels of the I/O modules symbolic names as listed in the parts list for your AS.

Steps

1. Select CPU symbol, open object properties 2. Cyclic Interrupt tab: assign PIP to the OBs 3. Cycle/Clock Bit Memory tab -> check OB85 call 4. Assign symbolic names for I/O channels

Process image partition The CPUs (from about 1998) support process image partitions. The process image partition is defined in the CPU and for each I/O module (see next section). The process image is updated by the system through connection to an OB you selected. The procedure is as follows. Select the CPU. Open its Object Properties. Select the "Cyclic Interrupt" tab. For example, for OB32, select process image partition "PIP1". For OB35, select process image partition 'PIP2". Select the "Cycle/Clock Bit Memory' tab. Check or make the following settings: OB85 call with I/O access error: With incoming o r outgoing errors only Size of process input (output) image: both >= 1024 (default setting depends on the CPU used;

Setting parameters for I/O modules In the upper window, select the ET 200M you want to configure. In the lower window, select the individual line for the relevant module. Then, right-click and select Object Properties -> Addresses tab Click the "Process Image" field. Select the process image partition you want (such as "PIP1," according to the OB - process image partition assignment for the CPU made in the previous section). Repeat the procedure for each I/O module. This is how you determine how quickly and frequently the CPU updates the data for the individual module. "Inputs/Outputs" tab Here you can make individual adaptations to the connected process signals and their characteristics for the module and its inputs/outputs. Symbolic channel names Select the line with the I/O module. Then, right-click and select Edit Symbols to add the symbolic name and possibly a comment for each channel. You enter this symbolic ID in the symbol table for the S7 program. When you insert the new driver blocks in a CFC chart, you "only" have to recognize this name again. The drivers automatically take the settings on the modules, their inputs/outputs, and their slots into consideration. Additional specifications are not needed. Based on this unambiguous signal name for CFC, all additional settings are read from the HW-Config and parameterized on the drivers. Proposal

Name the module inputs as follows: Module

Compile and download your AS's hardware configuration to your target module.

Compile

Click the Save and Compile icon ("1" in the slide). Or, alternatively, you can use the menu command Station -> Save and Compile

Download

Ensure that the CPU is in STOP mode and that the keyswitch is set to STOP or RUN_P. Click the icon "2" or, alternatively, use the menu command PLC -> Download to Module The first time you download, the AS is downloaded with the CPU in STOP mode (if it is still running with an old configuration, the download dialog box offers a stop and restart option). If you make changes later, they can also be downloaded w ith the CPU in RUN mode (certain rules apply). This assumes th at suitable PCS 7 driver blocks are already running in the CPU.

Remark

For the sake of completeness, a description of downloading in RUN mode is provided on the following pages. If you need to make changes to the hardware configuration during the course of the project, follow the download procedure described there. Now the configuration of the AS from the first project is complete. A similar procedure must also be performed for the PC stations that are being used as ES or OS (see the section "Configuring the PC Station” in this chapter).

After the download procedure is started in RUN, STEP 7 first checks whether the changes can be downloaded in RUN. The current online configuration of the CPU is also taken into account. If it is not possible to download the changes (e.g. offline changes to the CPU parameters, such as e.g. PIP assignment), a screen is displayed indicating the cause. You can then press the Help button to display a description of the error and how it can be eliminated (if this is possible). You can also start a preliminary check of the CiR compatibility by activating the menu option in the HW Config Station -> Check CiR Compatibility This checks whether the configuration changes that were made since the last download can be downloaded to the automation system in RUN. The check is performed offline. An online connection is not required.

If the check returns a negative result, we recommend discarding the changes. You are lucky if you didn't save the modified configuration before the check! You can now exit the HW Config. You are prompted whether you want to save the changes. Respond with NO! This way you can discard all changes that are not CiR-compatible. General Recommendation After a successful download, make small changes to the HW Config and note or remember the changes you have made. Should the result of the CiR check be negative, there is no major loss when you discard the changes. If, however, the changes are necessary, you will have to resort to downloading with the CPU in STOP mode and then reboot. For a detailed description, please refer to the manual "STEP 7 - Modifying the System During Operation via CiR” that was installed on your ES. The programming instructions in that manual can be disregarded under PCS 7, as the PCS 7 driver blocks take care of the specific cases.

Some properties that are relevant for the CiR are already checked during configuration. In the above example, the address range reserved by the CiR module is not sufficient to allow insertion of another analog module. It is not possible to download changes made to the reserved range in RUN (see next page).

Any subsequent changes to the reserved range for this ET 2Q0M cannot be downloaded in RUN, i.e. if insufficient address space was allocated before the first download. How should we proceed now? If the CiR object on the DP subnet still has sufficient address room for slaves, an additional ET 200M can be inserted there and fitted with modules. In the latter case, you should create sufficient reserve addresses so that the new rack can be completely equipped.

PC Station

The PC can be used as ES or OS or both. It must however be set up once, immediately following installation of PCS 7. Then it can be changed later. C om m issioning Wizard The Commissioning Wizard appears after the installation and detects (via Win2000 functionality) the network cards (CPs) on your computer. You need to make settings for the CPs (explained in more detail later) It is also automatically started if new or different communications cards (CP) were installed on the PC after it was last shut down. Set PC Station

After the Commissioning Wizard has finished, this tool opens and the modules/CPs recognized by the Commissioning Wizard are displayed. For each module, the operating mode is displayed in the "General" tab: "Configured Mode": The CP (module) is loaded from the project by the Hardware Config (configured). The preset configuration created there determines the behavior of the CP (actual configuration). "PG Operation": In this case, the CP is configured via the properties. or via START-> SIMATIC->SIMATIC NET->Settings -> Set PG/PC interface PCS 7 version)

(as you may already be familiar with from the previous

SCE

The Station Configuration Editor is displayed in the form of a table. Only the CPs that are set in "Configured Mode" initially by the "Commissioning Wizard" (or later by "Set PC Station") are entered in the table. If a CP is switched from "PG Operation" mode to "Configured Mode" in the "Set PC Station" tool, it is automatically recorded in the SCE table. When the mode is set back to "PG Operation", the CP is removed from the SCE again.

Remark

Each component (also the individual CP) is assigned an index in the SCE (like a "slot" in the table). You can change the slot/index in the SCE via: Select CP and Edit or by moving it with the mouse.

The Set PC Station tool is launched via the Windows Start bar Start -> SIMATIC ^ SIMATIC NET

Set PC Station.

The "Modules" and "Access points" tabs are of interest for PCS 7. Modules

All communication modules detected by the Commissioning Wizard are listed here.

CP 5611

The CP can be used for interconnection via MPI or PROFIBUS DP. It is set to PG Operation, as it is only used for PCS 7 V6.1 in some specific cases.

CP y (see page 26)

In the example, "Configured Mode" is displayed as the mode type for the internal LAN interface (Intel). Index "4" means that this module was entered in the SCE on "Slot 4". It can be moved there if required. The settings for the module are loaded from the project after the HW Config is opened. The module is required as a connection to the plant bus.

CP x

In the example, "PG Operation" is displayed as the mode type for the 2nd LAN interface (Xircom). This module is not displayed in the SCE, is not used in the HW Config, and is not loaded from the project. The module is used as a connection to the terminal bus.

Remark


To change the operating mode (PG Operation <->Configured Mode) you must have administrator rights under Windows. In Configured Mode, the parameter settings for the module are loaded from the project. In "PG Operation", you set the parameters.

The available access points are listed here. The assigned interface parameter settings and module are displayed for each access point. Applications that use the protocol libraries (DLLs) directly use the name of an access point to access the module. Double-clicking on an access point opens a dialog where you can make changes to the assignment. The access point "S70NLINE" is the relevant access point for online operation of the ES. Which device (interface) the SIMATIC Manager uses to communicate with the ASs is determined by the access point. For example, if S70NLINE is set to CP5611(MPI), the SIMATIC Manager will only try to access the other components via this module with its MPI settings. On the other hand, if the access point S70NLINE is set to "PC internal(local)", the SIMATIC Manager tries to find the path to the other components on the basis of the configured networks. If several paths/gateways are possible, then a screen form will appear offering a selection of the available gateways.

Remark

This setting is also required in order to download the configured ES/OS configuration "to the PC". It is also used for central configuring in large-scale projects (multiprojects).

Exercise (info option) Set up the Station Configuration Editor so that Index 2 (row 2) contains a WinCC application while Index 3 (see slide) contains the Ethernet OP for the plant bus. Enter the Windows name of your PC as the station name. Note 1

The SCE initially only shows the communication modules that the Commissioning Wizard has found that are in "Configured Mode".

Procedure

Start the Station Configuration Editor from the desktop (or alternatively, via the icon in the Windows taskbar). Select the row with the contents you wish to delete, then right-click and select Delete to remove the contents. If it was a CP, it is removed from the Station Configuration Editor, but remains in the Set PC Station tool where it is switched to PG Operation mode. If the correct component was already entered, but in the wrong row, you can move it to the correct row with a drag-and-drop operation. If you want to add a new component, select the row in the table, right-click and select Add. A screen form opens where you can select the component you wish to insert. An application should run on the PC according to its function in the network. If the PC is used as ES, it needs a slot/index of type "Application” or "WinCC application" in the SCE. If the PC is used as OS, it needs a slot/index of type "WinCC application", "WinCC application (stby)" or "WinCC application client" in the SCE. Which option to select depends on whether the OS is configured as a single server or redundant server, or if the OS is used as a terminal (client).

Application



Page 30

System Config

Once the configuration is completed on the PC, it must be loaded from the HW Config (which is contained in the project). Then the PC is ready to assume the role assigned to it (ES or OS) Note

Later when the connection is configured, the application represents the contact point on the PC side for the CPU from the AS side.

Note 2

The previously described procedure also functions in Version 7.0. A disadvantage is the double configuration (once as SCE on the PC and additionally in the hardware configuration of the PC station, in the PCS 7 project). With Version 7.0 and higher, the SCE can be derived from the project once the hardware configuration has been created in the project. Initial creation of the SCE is then omitted.

2. The OS was created as a SIMATIC PC station. The PC station was also configured as a component with the HW Config tool. In the component view of SIMATIC Manager, select the SIMATIC PC station, right-click and select Open Object (or double-click the configuration icon). In the hardware catalog, open the node "SIMATIC PC Station", select the components and use the mouse to drag them onto the PC rack. You need to match the slot in the rack with the Station Configuration Editor (SCE). The matching must take place before downloading the configuration to the PC (see next page).

Components

The components are as follows:

WinCC Application

This corresponds to the OS software. However, the index (slot within the rack) does not match the position in the SCE (Station Configuration Editor). It needs to be adjusted as follows: - Use the mouse to drag the WinCC application to the same position in the HW Config rack as in the previously configured SCE, - Or, the SCE is automatically configured (see next page) if it is still empty. In the latter case, the slot/index in the HW-Config is now irrelevant.

CPs

2. Communications processors for connecting the PC to the networks (MPI, PROFIBUS, Ethernet). In our exercise do not configure CP 5611 as it is running in "PG Operation" and is not loaded. Select the Ethernet CP installed in your ES/OS PC configuration and drag it onto the PC rack. Set the Ethernet address (MAC address) in the CP properties according to the parts list for your workstation. In our example, deactivate the Internet protocol (TCP/IP).



Page 33

System Config

Note

If an IE General CP/Softnet CP Is used (e.g. 3Com or LAN onboard), then it is generally not possible to change its address and the address in the HW Config must match the address displayed in the "Set PC Interface" tool.

OS

After you compile or complete the HW-Config with with a Save operation, an OS station is created in the component view of the SIMATIC Manager under the SIMATIC PC station. Select the station, right-click and select Object Properties Then, the station as ’’OSxx", where xx is the number of your station (e.g. O S O I).

PG/PC interface


Change the S70NLINE interface to "PC internal (local)". While this setting is irrelevant at the moment, you can make it now since you already have the SIMATIC Manager open.

4. You can only download the PC if the access point S70NLINE was set to "PC internal (local)". Set the access point accordingly via Set PC Station. As an alternative, you can also set the access point from the SIMATIC Manager via Options -> Set PG/PC interface Access point S70NLINE -> PC internal (local)

Note 1

Compile from the HW-Config Tool (symbol 1 in the slide). The compilation process can take several minutes (depending on the computer), as a complete WinCC project is generated for the WinCC application.

Load

To download the PC configuration, select symbol 2 (see slide).

Compile

Acknowledge the dialog boxes that appear. If error messages are displayed, this could indicate that the PRESET and ACTUAL states are incongruent. Open the Station Configuration Editor and look at the symbols in the Components tab, Status column. For more information, activate the help button in the Station Configuration Editor. Also check the Diagnostics tab! Have you obtained the SCE through "Configure station"? Note 2

In order to enable all AS and OS of the projects contained in a multiproject to be downloaded from the central ES, the PC interface must remain set to PC internal (local) for the duration of the project. It is necessary, however, to merge the different networks of the projects (make them known). The NetPro tool is used in the multiproject for this purpose. You can also use it to set up the S7 connections required for the online data transfer between the AS and OS. The next pages show you how to merge Ethernet networks and create the S7 connection between AS and OS.

Launch NetPro for both projects (PRO_OS and PRO_AS) and merge the Ethernet subnets there. Then create an S7 connection from the OS to the AS and download the connection to both devices (AS and OS).

Steps

1. Start NetPro for the OS project. 2. Start NetPro for the AS project. For clarity, arrange both side.

3. Merge the Ethernet subnets. 4. Create the S7 connection called OS01_AS01 between the and download this to both stations. Procedure

OS and the AS

1. Select the PROMOS project in the SIMATIC Manager. Click the NetPro icon (see slide). NetPro opens with a window displaying the networks from the PRO_OS project. 2. Select the PRO_AS project in the SIMATIC Manager. Click the same NetPro icon. As NetPro is already open, it appears in the foreground again and displays a second window with the networks from the PRO_AS project. Select the menu command Window -> Arrange -> Tile Vertically to display both project-specific networks side by side. At this point they are still independent even if, for example, the Ethernet subnet has the same name in both projects (plant bus, see next slide).

Internally the merged subnets are assigned a common ID (identifier) so that they are available as if they were a uniform subnet. One result of the common ID is that the setting for the access point ''S70NLINE -> PC internal (local)" is sufficient for the SIMATIC Manager to find and suggest a route for loading the devices! You just need to download this new information (e.g. from the HW Config) to the ES first! Then you can download an AS too with the same setting.

Each connection is assigned an ID:

Recommendation

•

On the PC (application) side, this ID is a name (e.g. S7_Connection_1)

•

On the AS (CPU) side, the ID is a value.

Change the default name to a meaningful name(e.g. OS01_AS01). This makes it easier to see who the connection partner is in the connection table of an AS (CPU). Moreover, it is advantageous for the online test of a configured OS on the ES-PC (keyword "Start OS Simulation") before the active OS is loaded.

When downloading the connection for the first time, select the stations (AS and PC) you would like to download, then select PLC -> Download to Current Project -> Selected Stations to download the stations.

Notice

This method requires you to stop the CPU/application for a short duration (seconds) and then restart it! The network configuration is downloaded independently of the HW Config download.

Tip

If you do not want the AS to go to STOP (for example, if this is not permissible for the process), use a different method: Select the AS and download by selecting PLC -> Dovsnload to Current Project -> Connections and

Gateways.

For the OS select the relevant connection in the connection table and download it by selecting: PLC -> Download to Current Project -> Selected Connections.

The standard view (left window) displays the devices of the individual project only. The subnets are displayed both with their project-specific name and their merged name. You can select the different components and set them via the relevant menus (usually Object Properties).

Cross-Project View This view serves mainly to view information that is relevant at the level of the project (no configuration of the components). For example, from here, you can download the connection data to the listed components. Remark

Each node (CPU or application) has its own, limited connection table. Individual, downloaded connections cannot be deleted online. Should you need to delete them, you first need to delete the connection in the offline table and then download the full table by selecting PLC -> Download to Current Project -> Selected Stations However, as described above, the stations must be set to STOP for a brief duration!

Additional Information When configuring connections, the SIMATIC Manager provides them with IDs in the same sequence as they were created. If both nodes exist in the multiproject, you can select the partner, and each one is automatically assigned a separate ID for this connection. If the partner is not yet available, you can reserve an ID as described in the next section. Connections in Unknown Project To do this, highlight the CPU in your project, the connection table appears, select an empty line, right-click and activate Insert New Connection to start the process. Then select as your Connection Partner: the option "In unknov/n project" and then the Properties of the S7 connection. Under Properties, enter a connection name/reference (circled on the slide) and specify whether the local CPU is to establish the connection (circled on the slide). Only one partner in the connection is permitted to establish an active connection. If the connection has not been closed, it will be displayed as an error when NetPro is terminated, by way of a reminder. Later, when the other projects have been incorporated into the multiproject, connections from the various projects with the same reference are merged when the projects are adjusted. After that point, the address details are known for both stations and the connections can be loaded into both. Note

The project merge can either be started from the multiproject or - like with the subnet merges - in NetPro by activating the menu command Edit -> Merge Connections...

C onfiguration

A PCS 7 environment consists of ASs (S7 components with suitable I/O), PCs used as an ES or OS and networks between these components. There is an actual configuration and a preset configuration for each component. In addition communication connections must be set up between the stations.

Actual configuration

With an AS, this is determined by the specific structure of the available hardware (rack, power supply, CPU etc.). In our case, the hardware was provided in our training room. With a PC (used as ES or OS), a virtual structure is created using SIMATIC tools for the workstation configuration (Set PC station, or Station C onfiguration Editor). You need to set up the structure yourself (this is generally done when the PCS 7 software is installed on the PC). With V7.0 and higher, this can be simply carried out from the central ES (C onfigure Station).


The preset configuration is created in the SIMATIC Manager within a project on the ES by using the HW-Config tool in the project. It contains project-specific parameter settings for the devices used. After completion, the preset configuration must then be transferred via the network from the ES to the respective station (AS or PC). In doing so, the load procedure must find the components of the preset configuration in the actual configuration.

Connection

NetPro is used for this. Connections are created between: ES-AS, OS-AS, AS-AS (if the latter need to exchange data among themselves). You also need to download these connections to the respective stations.

Remark

All tools are integrated in the ES software and can either be called directly or in the context of the components to be configured.

Configuration

Hardware components are used within the project. These include the automation systems (AS), PCs as operator stations (OS) or engineering stations (ES), and the networks.

Components

In the multiproject, select the required project, then right-click and select select Insert New Object and then as required: •

"SIMATIC 400 Station" for an AS

•

"SIMATIC PC Station" for an ES or OS

• "Industrial Ethernet" for the plant bus or terminal bus,etc. When you select the object to insert, a symbol is generated to represent each device and serves as access point to the configuration. HW Config

The "Hardware Configuration" tool or "HW Config" for short is used for this. HWConfig is used in the same way for both AS and ES.

AS

To configure the AS, use the mouse to select the symbol representing the required AS in the SIMATIC Manager (component view), then right-click and select Open Object The tool is launched. As an alternative, you can also double-click the hardware symbol in the right pane.

ES

To configure the ES, use the mouse to select the symbol representing the required PC in the SIMATIC Manager (component view), then right-click and select Open Object The tool is launched. As an alternative, you can also double-click the configuration symbol in the right pane of the SIMATIC Manager.

To start, the configuration should reproduce the configuration of the devices. The example in the slide shows an AS configuration. The components shown here offer settings screens (usually accessible via the object properties). If the configuring engineer is knowledgeable about the options available and application at hand, he or she can optimize the components’ settings offline first. Then these settings need to be supplied to the devices (by online download to the target systems).

Using HW Config You have created one project with an AS and one with an OS. The hardware configuration must be adapted to the AS and OS you are using. In doing so, the parts lists for the ASs and PCs in use must be taken into account. Terms

Tip

Pasting

The HW Config tool refers to a station (AS o r PC). In the right pane, a tree structure displays the SIMATIC components (hardware catalog). After selecting a com ponent (arrow 2 in the slide), the associated Order No. and a brief description are displayed in the com m ent field (arrow 3). If you have not been able to locate the module (as it is not a current PCS 7 module or is an older module) select the "Standard" hardware profile (arrow 1 in the slide) and search again. There you will find all S7 modules that are known in the current version of the SIMATIC Managers. If you know part of the order number or designation, you can enter it in the Find box and click the button (arrow 4) to find the module. The search is only conducted for the selected profile. Please note that the part designation can occur multiple times! (If this is the case, continue the search.) In the SIMATIC Manager select the station/AS in component view, then right-click and select Open to open the HW Config.



System Config

Then proceed as follows: • Search in the catalog and check the order number and if necessary the firmware version of the racks, power supply, and CPU in use (arrow 3). • Use a drag-and-drop operation to insert the located modules in the left window. • Select the module in the left screen, then -right-click and select Object Properties... then set the parameters for the module. Replace

To replace a rack (or a module inserted in the rack) search for the new, required module in the hardware catalog. Take the hardware profile setting into account when doing so. The comment field (arrow 3) displays the corresponding order number and brief description for the selected component (arrow 2). Select the correct component, "drag” it with depressed left mouse button across to the rack/module symbol and drop it there. If the exchange is possible, a message is displayed with the order numbers of the two components and must be acknowledged. If the exchange is not possible (because the old/new components are not compatible), the mouse pointer will change to a crossed circle. In this case, the settings of the old module should be documented before deleting the module and replacing it with a new one. Then transfer the settings as appropriate or make new settings.

Note

If you have selected an incorrect slot, you can drag the module to another location with the mouse. The new location must be free and wide enough (i.e. correspond to the number of slots required by the module to be displaced).

Remark

The catalog profile (arrow 1 in the slide) was set up with the PCS 7 installation. You can edit the profile (s7hpro0) that is automatically created by selecting Options -> Edit Catalog Profile Here you use the familiar Windows procedure to copy objects from the standard profile (one window) to the new profile (the other window). After completion, the new profile can be saved via Profile -> Save as... The newly created profile is offered for selection in the profile box.

Exercise

Configure the modules for the central part of your AS. Use the parts list for vour AS as your guide! (The example refers to the "Saarbriicken" training room in the Mannheim Training Center.)

Steps

1. Insert the rack (UR=Universal Rack) 2. Insert the power supply (PS=Power Supply) 3. Insert the CPU or supplement the integrated DP interface. Rename the DP subnet and check properties 4. Insert and set CP for PROFIBUS DP (if available) Register CP 443-5 Ext as DP master Rename the DP subnet and check properties 5. Insert and set CP for Ethernet Create a new Ethernet network for the plant bus and rename it Assign or verify MAC address, disable TCP/IP protocol

Procedure Open HW Config

In the project, select the ASxx to be configured (your AS), and right-click and select Open object Use the hardware catalog to locate and configure the components (rack, PS, CPU, CP and I/O modules) in the HW Config for the station. If you cannot see the catalog, select View -> Catalog to activate it.



System Config

Rack

In the hardware catalog select the desired rack SIMA TIC 400 -> RACK 400 -> UR1 then use drag & drop to move it to the top left window.

Notice!

For the catalog component you have highlighted, check the detail specifications in the lower catalog window pane (order No. and comment) so you can insert the correct components. It is possible that the CPU will not start up if you insert a component incorrectly! The slots in the rack are listed in rows. You can now populate each slot (you can also use "drag & drop”).

Power supply

Select slot "1". In the hardware catalog, select SIMATIC 400 -> PS 400 -> e.g. PS 407 10A and position it on row 1. This 10 A power supply occupies 2 slots.

CPU

Select the correct CPU from the hardware catalog (for example) SIMATIC 400 -> CPU 400 -> CPU 417-4 -> V3.1 and drag it to the next free row (row 3). The CPU with the integrated DP interface occupies two slots. The Properties screen opens. Select the New button to create a new DP network and enter a meaningful name (e.g. DP_subnet1, or DP_AS01 _int1, or DP_AS01_ext3). In the properties for the selected network check whether the DP protocol and the desired baud rate are set (default 1.5 Mbaud). The image displayed now represents the PROFIBUS DP with the "DP master system (1)" identifier. The ET 200M is later appended to this.

Networking CPU via MPI

This is no longer necessary with Version V6 and higher.

Remark

The new Ethernet CP from 6GK7 443-1EX11-0XE0 V2 supports direct addressing of the card via the known MAC address of the Ethernet CP, therefore, the initial loading via MPI is no longer necessary.

Additional DP subnet

If an additional CP is connected in the rack for another DP subnet (such as the CP 443-5 Ext), this CP must be inserted in the rack in HW Config and be connected with a DP subnet (as the second DP master). In the HW catalog, select: SIMATIC 400->CP 400-> CP 443-5 Ext, select the correct CP and use "drag & drop" to move the CP to the correct rack slot. In the screen overlaid for the PROFIBUS interface for the CP, select NEW to create a new DP network and then rename the network (for example, DP_ Subnet2).



Page 9

System Config

CP as DP master

Highlight the CP 443-5 Ext in the rack, right-click and select Insert DP Master System to name this system as the master for the new subnet. You can use the graphically displayed subnet for additional ET 200M devices or for PROFIBUS PA devices via DP/PA link/coupler modules. If you do not want to configure the CP (no DP hardware is connected, for example), you must disconnect it from the power source (remove it from the rack). If it is present in the rack but not in the hardware configuration, the CPU (depending on the firmware version) may not start up (remain in STOP mode) or may not be downloaded. Therefore, if this CP exists in the hardware, it must also be entered in the HW Config.

Ethernet CP

Ethernet is used as the plant bus by default. Insert the CP in the HW Config. In the HW catalog, select SIMATIC 400->CP-400->CP 443-1-> "Concrete CP" and position it in the rack. In the overlaid "Ethernet Interface Properties" screen -> Parameters tab, click the New button Then, create a new Ethernet subnet (if you have not already done so), rename the subnet (e.g., "Plant bus") and select this bus to identify the CP as being networked. Set a unique MAC address in the project, taking into account other nodes physically present on the bus that are not part of this project. It is advisable to use the ISO transport protocol for small networks as it provides higher performance. However, if you want to communicate over more spread-out networks that are connected with routers, use the ISO-on-TCP transport protocol instead. Please note the address-suggestion made in the parts list of your training aulomation_sysl em_and deactivate the IP protocol (clear the check box).

Remark

The hardware configuration is downloaded in a later part of the exercise. Here, the AS is loaded directly via the known MAC address of the Ethernet CP for the first time. For this to work, the access point S70NLINE must be active on an Ethernet-capable CP that is connected to the plant bus. (additional settings are described in the chapter "Configuring the Workstation" under Setting the PC Interface). The download also provides the CPU its parameter settings via the Ethernet CP (therefore the CPU is configured during this procedure). If you change the PC interface to the integrated Ethernet CP (LAN card or CP 1613), you can then download and debug additional data (hardware configuration and subsequent software) over the plant bus.

Then right-click and select Properties to open the screen form above. The CiR object must retain resources for future DP/PA slaves. Each slave requires up to 244 bytes (can also be less, depending on the actual I/O modules). There is also a maximum limit for the number of slaves that can be inserted in the subnet online. 1. The guaranteed number of DP slaves (ET200, DP field devices) must be parameterized in relation to future additions. If no "Extra Settings" are selected, the sum of input and output bytes is automatically displayed. 2. They must be taken into account as sum values for the settings in CPU Properties -> Cycle/Clock Bit Memory tab -> Size o f the process images (for all DP slaves on all subnets). The CPU properties cannot be changed online!

Note

The maximum CiR synchronization time has a default setting of 1000 ms. The time associated with the current configuration is displayed in the properties of the CiR object. The default time and the CiR download process can be influenced in the software. To this end, the system function SFC104 "CiR" can be called in a CFC (from the "Standard Library”). By parameterizing and downloading this, the CiR process can be influenced without stopping the CPU.

S IT R A IN Traring for Automation and Drives

As the selected IM 153-2 supports CiR, a CiR module is offered in the lower part of the window from slot 4. I/O Modules

Take the I/O modules and position them on top of this CiR module in the ET 200M table (as previously for the station, but now with modules from the ET 200M / IM 153-2 directory). This way the CiR module is shifted one place to the right, ready to receive the next I/O module.

Note: Addresses

The CiR m odule reserves an address range for inputs and outputs (the total of which is less than 244 bytes - they can be addressed via the slave). Using the module properties, you should reserve sufficie n t address space for modules to be inserted at a later point in time. If you want to add address space later, you must switch the CPU to Stop mode. For example, if the planned configuration is one ET 200M for 8 modules (the CQrrespondinQ.bus._niQdul.es (hardware) must.be instaltedjjght fronLthe_slari), and if the initial installation is equipped with 5 Al modules (8-channel), this means that 5x8x2=80 bytes input addresses are used. If you would like to add identical modules to the three remaining slots while the CPU is in Run mode, you will need to have reserved 8x8x2=128 bytes input addresses during the initial setup. 1 word=2 bytes per analog value are required.

Note about m odule replacement When using PCS 7 you can replace modules during operation. Select the ET 200, and right-click and select Object Properties -> Operating Parameters tab Then select the option "Module replacement during operation". The bus modules listed here must be installed in the rack. If you forget to set this

option and.replag.e_ajnodula later.during_r.untime. a rack.failure jnes.sage.is issued (as if all modules.had failed). The power supply for IM is not configured, but an external 24 V supply is possible.

S IT R A IN Trainingfcr Au'.omaton atd Drives

The DP master (CP or integrated DP interface on the CPU) cyclically scans the PROFIBUS DP subnet (circular arrow 1 in the slide). In doing so it passes data to the slaves (e.g. ET 200M for passing to the output modules) and reads back data from the slaves (which acquired them from the input modules). The data are passed through an IM internal buffer. During each cycle, the DP master writes/reads values to/from all its slaves. The buffer content forms an image of the inputs and outputs of the modules. The cycle time is called Ttr = Target rotation tim e and is displayed in the properties of the CiR object, here IM 153. The DP update cycle runs independently of the CPU program, but must be at least as fast as the fastest program that processes the process values. For evaluation in the user programs, the intermediately stored input data from the operating system are copied at a defined point in time from the buffer to a CPU memory area and output data copied from there are written back to the buffer at a different point in time. The programs can then gain read (I) and write (O) access to this "process image" memory area.

Synchronization

This ensures that the programs are working with consistent process data. This means that the operating system must provide for the updating of the process input image and freeze it, before starting the program. After the program has been executed and commands have been written in the process output image, the output image is sent to the DP master. However, as process signals and their associated processing operate at selectable repetition rates (slow/fast processes), it is necessary for their synchronization to match as well.



Page 15

System Config

Process image partition The CPU offers OBs with different speeds in which the user can execute programs. You can assign a process image partition to the OBs in the CPU properties - A ssign PIPs (e.g. OB32<->PIP1, OB35<->PIP2, OBx<->PIPs, where n=1 to 16 is dependent on the CPU). A t the same tim e a suitable PIP m ust be assigned fo r the individual I/O m odules in th e ir properties. Driver blocks are used in the PCS 7 software to input and output process data. These driver blocks m ust run in the same OB th a t updates the PIP o f the scanned I/O module. Note

It is useful when wiring the signals between modules to differentiate between slow and fast signals. A module should be assigned to a PIP that is capable of delivering signals to the software at sufficient speeds such that the fastest connected signal is processed currently. If signals are mixed on the module, this causes slow signals to be read quickly, wasting computing time.

Remember:

If you w ant many, it cannot be fast. If you w ant fast, it cannot be many. The CPU cannot co ntin uo u sly w ork in overload. A fter a program med, but lim ited tim e th is leads to CPU stop!

Exercise

The process image partitions are to be updated on the CPU: PIP " I ” by OB32 and PIP "2" by OB35. The I/O modules (in the example) must be assigned to process image partition "1." Give the individual channels of the I/O modules symbolic names as listed in the parts list for your AS.

Steps

1. Select CPU symbol, open object properties 2. Cyclic Interrupt tab: assign PIP to the OBs 3. Cycle/Clock Bit Memory tab -> check OB85 call 4. Assign symbolic names for I/O channels

Process image partition The CPUs (from about 1998) support process image partitions. The process image partition is defined in the CPU and for each I/O module (see next section). The process image is updated by the system through connection to an OB you selected. The procedure is as follows. Select the CPU. Open its Object Properties. Select the "Cyclic Interrupt" tab. For example, for OB32, select process image partition "PIP1". For OB35, select process image partition "PIP2". Select the "Cycle/Clock Bit Memory' tab. Check or make the following settings: OB85 call with I/O access error: With incoming o r outgoing errors only Size of process input (output) image: both >= 1024 (default setting depends on the CPU used;

Setting parameters for I/O modules In the upper window, select the ET 200M you want to configure. In the lower window, select the individual line for the relevant module. Then, right-click and select Object Properties -> Addresses tab Click the "Process Image" field. Select the process image partition you want (such as "PIP1," according to the OB - process image partition assignment for the CPU made in the previous section). Repeat the procedure for each I/O module. This is how you determine how quickly and frequently the CPU updates the data for the individual module. "Inputs/Outputs" tab Here you can make individual adaptations to the connected process signals and their characteristics for the module and its inputs/outputs. Symbolic channel names Select the line with the I/O module. Then, right-click and select Edit Symbols to add the symbolic name and possibly a comment for each channel. You enter this symbolic ID in the symbol table for the S7 program. When you insert the new driver blocks in a CFC chart, you "only" have to recognize this name again. The drivers automatically take the settings on the modules, their inputs/outputs, and their slots into consideration. Additional specifications are not needed. Based on this unambiguous signal name for CFC, all additional settings are read from the HW-Config and parameterized on the drivers. Proposal

Name the module inputs as follows: Module
