Overview

14.10.2005 PRO1_09E.3


The units installed in the field for automating technical processes, such as sensors, actuators, transducers and drives more and more make use of field bus systems for exchanging information with the higher-level controller units. PROFIBUS is an established fieldbus system which can be used by all automation equipment, such as PLCs, PCs, Human-Machine Interfaces as well as actuators and sensors, for exchanging data.

PROFIBUS-DP

PROFIBUS-DP is a protocol optimized for speed which was specially designed for communication between PLCs (DP masters) and distributed I/Os (DP slaves). PROFIBUS-DP is a low-cost, flexible substitute for transmission of signals on cumbersome parallel 24V and 20mA lines. PROFIBUS-DP is based on DIN 19245 Part 1 and the user-specific extensions in DIN 19245 Part 3. In the course of the European fieldbus standardization process, PROFIBUS-DP was integrated into the European fieldbus standard EN 50170.

Master Devices

PROFIBUS makes a distinction between master and slave devices. The PROFIBUS masters are in charge of data traffic on the bus. A master can send messages without being requested to do so, provided it is in possession of the token that entitles it to access the bus. Masters are also referred to in the PROFIBUS protocol as active nodes.

Slave Devices

PROFIBUS slaves are simple I/O devices, such as actuators, sensors, transducers, etc. They do not receive the token, that is. they can only acknowledge the receipt of messages or send messages (data) to a master on request. Slaves are also referred to as passive nodes.

Distributed I/O

All master systems consisting of a DP master and DP slaves that are connected using a bus cable and that communicate via the PROFIBUS-DP protocol are designated as distributed I/Os.

DP Master

As DP master you can install: •

S7-CPU with integrated DP master interface (such as CPU 414-2, etc.)

•

CP in connection with a CPU (such as CP 443-5, etc.)

Setti ng Up DP Master To configure a master system, proceed as follows: 1. Select the PROFIBUS interface X2 of your CPU and insert a master system (Menu Insert  Master System) 2. The dialog box "Properties - PROFIBUS interface DP" is opened. In this dialog you can define the following properties: •

set up a new PROFIBUS subnet or open an existing one

•

set the properties of the PROFIBUS subnet (baud rate, etc.).

•

define the PROFIBUS address of the DP master.

3. Acknowledge the settings with "OK". The following symbol appears: for the DP master system. This symbol is used as a "hanger " for the DP slaves.

Selecting DP Slaves


14.10.2005 PRO1_09E.5

•

Modules with integrated digital/analog inputs and outputs (compact DP slaves, such as ET200B).

•

Interface modules with assigned S5 or S7 modules (modular DP slaves, such as ET200M, ET 200S).

•

S7-200/300 stations with modules that support the "Intelligent Slave" function (such as CPU 215-DP, CPU 315-2).

To configure a DP slave, proceed as follows: 1. From the "Hardware Catalog" select the desired compact DP slave (such as ET200B) or the interface module (such as IM151-1 Standard for ET200S) for a modular slave. 2. Drag the symbol (such as IM151-1 Standard for ET200S) onto the symbol for the master system: The dialog box "Properties – PROFIBUS interface DP" is opened. Here you can set the following properties: •

properties of the PROFIBUS subnet (baud rate, etc.).

•

the PROFIBUS address of the DP slave.

3. Acknowledge the settings with "OK". A configuration table is attached to the symbol (icon) that represents the I/O configuration of the compact slave or the rack of the modular slave. 4. For a modular DP slave, you now insert the desired modules from the "Hardware Catalog" into the configuration table. The addressing and parameter assignment of the modules is then handled similar to the configuration of the centrally inserted modules.

2. Verify the preset slave adress. These are the switches on the IM 151-1 interface. In the example, the slave address = 4. 3. Change the addresses of the mixed DI/DO module in the UR0 Universal Rack to IB 88 and QB 88. As the input and output addresses in the ET200 S configure IB 8 and QB 8. 4. Connect the ET 200S to the DP interface of the CPU. 5. After "Save and Compile" download the configuration into the CPU. 6. Verify that the configuration is error-free. The error LEDs - Group error (SF) and bus error BUSF must be dark on the CPU. 7. Test your program.

Notes

•

For the ET200S, to combine the addresses for the two input or output modules into one byte, use the "Pack Addresses" button. Remember to select the two modules first.

•

Any changes you make to the PROFIBUS address of a slave only becomes effective after Power OFF/ON - Transition.

•

You will find more information about PROFIBUS DP in advanced courses or in the self learning media under the topic of PROFIBUS.

Overview

14.10.2005 PRO1_09E.7


With SIMATIC HMI, there is a field-proven HMI system for user-friendly process control and monitoring available for the SIMATIC S7. The products range from simple text display to the process visualization system. SIMATIC S7 and SIMATIC HMI are completely harmonized and integrated. This greatly simplifies the use of the SIMATIC HMI control and monitoring system. •

The SIMATIC S7 has already integrated HMI services. The HMI system requests process data from the SIMATIC S7. Data transmission between SIMATIC S7 and SIMATIC HMI is handled by the two operating systems and does not have to be taken care of by the user. SIMATIC HMI systems can be connected directly to PPI (S7-200) and MPI or PROFIBUS (S7-300 and S7-400) and Industrial Ethernet (WinCC). Operation using PROFIBUS or Industrial Ethernet also makes it possible to handle process operating and monitoring over greater distances.

•

Numerous features from the uniform data base and symbols to the same user-friendly Windows-oriented user interface make it easy to use HMI systems.

Introduction


14.10.2005 PRO1_09E.9

You configure your project on a PC or programming device (PG). You then generate the configuration under ProTool/Pro and download it to the PC/OP/TP. If the PC/OP/TP is connected to the PLC, the PC/OP/TP displays the current values in the tags and graphics. The three phases of working with the configuration data are shown in the slide.

Configuring

The configuring process consists of various par tial steps: 1. Defining the PLC and the type of connection (MPI, PROFIBUS – DP, Industrial Ethernet etc.) 2. Making general settings for the PC/OP/TP (defining the current connections etc.) 3. Generating objects such as tags, screens, messages. 4. Downloading the generated database to the HMI system via MPI, PROFIBUS - DP, or Industrial Ethernet The configuration is stored as a source file - .pdb in your S7 project (Directory ... TDOP). After the compiling phase and downloading, one of the following file types is created depending on the type of device:

Editors

•

.fud

for RMOS-based operator panels

•

.fwd

for Windows-based HMI systems

ProTool/Pro includes a set of editors (tools) for configuring the different types of objects. You create each object under a symbolic name. You must specify this symbolic name time and again, for example, when c reating, editing, referencing or deleting the object.

SIMATIC S7

Date: File:

Tag

Process tags are used to make the data exchange between SIMATIC S7 and the HMI system. Tags are created in the configuration with ProTool/Pro and are assigned to a CPU data area for this. The HMI system cyclically reads out the tag values and displays them in an output field, for example.

Data Areas

In the configuration of tags, the following CPU data areas - global tags - can be used: •

Data blocks (DB)

• •

Bit memories (M) Inputs (I) and Outputs (Q)

•

Peripheral input (PI) and Peripheral output (PQ)

•

Timers (T) and Counters (C)

HMI systems also recognize local tags without process connection. That is, these tags are processed exclusively internally and do not require any communication resources. Communication

The operator panels can communicate with the PLC using the MPI or PROFIBUS DP or Industrial Ethernet bus systems. The S7 protocol is used here. Communication is organized through the S7 CPU and HMI system operating systems. User programming on the S7 is therefore not necessary. An operator panel can exchange data with several PLCs simultaneously.

Updating

Data transfer between SIMATIC S7 and the HMI system takes place cyclically. That is, process tags are cyclically read and written depending on the configured update times.

Example: Defining an Output Field

Output field

Property of “ Act_quantity“

SIMATIC S7

Date: File:


14.10.2005 PRO1_09E.11


Purpose

Output fields display current values from the PLC on the operating panel. You can choose to display the values as numeric, alphanumeric or symbolic. In the example, the value of the actual quantity is to be displayed in the screen "Belt". The actual quantity is recorded in the CPU program in the FC 18 block when a part has passed through the light barrier.

Configuring

You configure output fields for numeric and alphanumeric values in the opened screen in the toolbar "Screen objects" by selecting the symbol or through "Insert"  "Output Field".

In the Properties window of the Output Field, you define the Display, Display Options and the Alignment. You use the "Value" selection field to select an already existing tag. If it is a new tag, you use the icon

and to edit you use the icon

General

In the slide you can see the relationship between the tag MW 20 (Actual_ Quantity) and the tag configuration in ProTool/Pro.

Properties Window Output Field

After selecting the output field, you right click and select the menu option Properties to get to the screen that you see to the left in the slide. In our example, you use the icon "Edit" to get to the screen "Tag".

Properties Window Tag

In the slide to the right, you can see the existing configuration of the tag. It has the name "Actual_Quantity" and is assigned to Controller_1 (up to 8 different controllers possible). The value is read every 200ms (acquisition cycle) from the CPU and displayed as an Integer (type).

Symbols

In the tag declaration, the symbols in the S7 program can be accessed. You do not need to know the absolute addresses from the S7 data management.

Notes

-

In the property dialogs of the buttons etc., you will find, under the "Functions" tab, the assigned actions (selected functions in events…).

-

Through the "Parameters" button, you can take a closer look with reference to the assigned symbol table at the selected tag with its properties (Edit Tag).

Setting the Terminating Resistor

14.10.2005 PRO1_09E.21


Switch on the terminating resistor on the first and last nodes of a segment. To do this, you open the cover of the bus connector and set the switch to the ON position.

The PROFIBUS is only correctly terminated if the power supply of the node in which the terminating resistor is inserted is actually switched on. If this is not always the case, the PROFIBUS can also be terminated with an active RS485 terminating resistor. The terminating resistor then receives a permanent power supply separate from that of the other I/O components or supplied to it before the I/Os. Termination of the bus system enables the nodes (for example ET 200L) to be connected and disconnected at will, without causing malfunctions.

Segment Length

In the slide you can see the cable lengths of a segment without a repeater depending on the transmission speed.

RS 485 Repeater

An RS 485 repeater boosts the data signals on the bus cables and connects bus segments. You will require an RS 485 repeater, if: •

more than 32 stations are connected to the bus,

•

bus segments are to be operated ungrounded on the bus or

•

the maximum cable length of a segment is exceeded.

If you set up the bus with RS 485 repeaters, only a maximum of 9 RS 485 repeaters may be switched in series. The maximum cable length between two nodes is 10,000 meters at 9.6 to 187.5 kBaud.

General

Profibus cables can be produced quickly and error-free with Fast Connect. You require a special stripping tool, cable and connector for Fast Connect.

What to Do

1. Measure the cable length by placing the cable on the template. 2. Place the measured cable ends in the stripping tool. Limit for the placement depth is the pointer finger of the left hand. Fasten the cable in the stripping tool. Turn the stripping tool clockwise four times to strip the cable. 3. Pull the closed stripping tool from the cable end. The residual cable parts remain in the tool. After opening the tool you can remove the residual parts. If the white filling did not come off during stripping, you can remove it by hand. To make it easier to remove the protective foil cut it carefully between the wires using a screwdriver. Remove the protective foil from the wires.
