1.1 Basic Control Loop In any process plant, the parameters generally measured are Level, Flow, Temperature, Pressure etc… The transmitter converts the process input into a 4-20mA current signal. This signal is given as input or process variable (PV) to the controller. The desired value is given as the set point or set variable (SV) to the controller. The function of a controller is to match the PV with the SV and make the deviation zero. In order to achieve this, the controller checks the deviation continuously (DV=PV-SV) and tries to make the deviation zero. The controller generates the output or the manipulated variable (MV) based on the deviation. The generated MV is also in terms of 4-20mA current signal.
However the final control element in most of the cases is pneumatically operated control valves. Hence an I/P converter (Current to Pneumatic signal converter) is used to convert the 4-20mA current signal to 3-15psi or 0.2 to 1 kg pressure signal which is used to operate the control valve.
1.2 Process Control Methodology For the controller to match the process value with the set value and calculate the manipulated value, various control methodologies are used. The commonly used control methodologies are: Feedback Control: It is a control in which the controller continuously checks the deviation between the input and the set point and always corrects the input to match the set point. Feed forward Control: It is a control in which corrective action is taken by measuring the disturbance and directly driving the final control element before it affects the process. Sequential Control: It is a control which successively advances each control step in accordance with a predefined sequence.

1.3 Process Control Systems A process control system comprises of multiple simple and complex control loops. Process control systems are primarily classified into: • Analog Control Systems • Digital Control Systems
1.3.1 Analog Control System Analog control system uses operational amplifiers to do the control function. Operational Amplifier
Transmitter 1 to 5V DC Signal Conversion
4-20 mA DC
I/P Set Point
Final Control Element
In an analog control system, the process parameters are measured by the transmitter. The transmitter generates 4 to 20 mA current signal corresponding to 0 to 100% of the process parameter measured. This signal is converted to 1 to 5V DC and given as input signal to the operational amplifier. The desired set point is also given to the operational amplifier. The operational amplifier calculates the output based on the input and the set point. The 4 – 20 mA current output is given to an I/P converter and then to the final control element.

Processor In a digital control system, the process parameters are measured by the transmitter. The transmitter generates 4 to 20 mA current signal corresponding to 0 to 100% of the process parameter measured. This signal is converted by signal converter into a voltage signal. Analog to Digital Converters are used to convert this analog signal to digital signal. This digital signal is given to the microprocessor for processing. Digital Control system uses microprocessors to do the control function. Digital control systems are preferred over analog control systems since it is easy to interface with computers for data analysis.
1.4 Digital Control Systems Digital Control Systems are further classified into: • Centralized Control Systems (CCS) • Distributed Control Systems (DCS)
1.4.1 Centralized Control System CCS is a centralized control, centralized monitoring system. All the inputs from the field are given to a single CPU. The relevant set points are also given to the same CPU. The outputs are also taken from the same CPU.

Set Points In a Centralized Control System, all the field inputs PV1 to PVn are fed to a single CPU, the relevant set points SV1 to SVn are also given to the same CPU and all the outputs MV1 to MVn are also taken from the same CPU. Hence if the CPU fails, the whole plant gets affected.
1.4.2 Drawbacks of Centralized Control System • •
If the CPU fails the entire plant gets affected. Redundancy concept is not available.
TE Y109JA01E-VPOP
8 1.4.3 Distributed Control System DCS is distributed control and centralized monitoring system. In a Distributed Control System, the control function is distributed, but the monitoring is still centralized. All the n field inputs are not fed to a single CPU. Instead they are distributed among multiple CPU’s. In DCS terminology, CPU’s are referred as Field Control Stations (FCS).

1.4.4 Advantages of Distributed Control System •
Control function is distributed among multiple CPUs (Field Control Stations). Hence failure of one FCS does not affect the entire plant.
•
Redundancy is available at various levels.
•
Instruments and interlocks are created by software.
•
Generation and modifications of the interlocks are very flexible and simple.
•
Information regarding the process is presented to the user in various formats.
•
Field wiring is considerably less.
•
Maintenance and trouble shooting becomes very easy.
•
Cost effective in the long run.

1.5 Distributed Control System In a Distributed Control System, the control function is distributed, but the monitoring is still centralized. The basic components of a DCS are: • Field Control Station. • Operator Station. • Communication Bus.
FCS (Field Control Station): The Field Control Station is used to control the process. All the instruments and interlocks created by software reside in the memory of the FCS. All the field instruments like transmitters and control valves are wired to the FCS. OPS (Operator Station): The operator station is used to monitor the process and to operate various instruments. Communication Bus: Communication bus is used to communicate between the Field Control Station and the Operator Station.

2.1 CENTUM VP
CENTUM VP is the world’s first Windows Vista ready DCS. The primary factors considered during the development of CENTUM VP are: • To realize ideal plant operation for customers. • To develop new Operation & Monitoring Environment for operations which provide more meaningful information. • To incorporate a modern, simple, intuitive look and feel. The basic frame of the new CENTUM VP HMI is designed to facilitate simple and easy access to the right information. The system message banner at the top displays key information such as alarms and guidance that everyone must be aware of. The navigation bar to the left allows users to get to the right information quickly and efficiently.
TE Y109JA01E-VPOP

The intuitive consolidated alarm management system is now the standard alarm viewer in the new HMI, ensuring role-based delivery of actionable, prioritized information and advisories.
2.1.1 CENTUM VP System Components CENTUM VP DCS has the following minimum system components. The Field Control Station (FCS) This is the interface between the field instruments and the control room. This is the component where all the control functions are executed and hence is a very important and critical component in the overall system. The Engineering / Operator Station (ENG / HIS) The operator controls the plant from here. The same component can be used to do the configuration changes. The operator station or the Man Machine Interface (MMI) is called the Human Interface Station (HIS) in CENTUM VP system. The component used for configuration is called the Engineering station (ENG). Both these components can reside in one hardware.
TE Y109JA01E-VPOP
15
The Communication Network The FCS and HIS are connected via a real time control network. This communicates all the parameters to and from the Field Control Station to the Human Interface Station. The communication cable for the control network can be an Ethernet cable or V net / VL net cable. The type of communication cable used is decided by the FCS used in the CENTUM VP system. If the communication network is Ethernet based, the system is called a V net / IP system and if it is V net or VL net based it is called as a V net system.

5.1 Instrument Faceplate The Instrument Faceplate indicates the status of a function block in the form of a window. The instrument faceplate displays the status and data of a function block, an instrument or contact I/O graphically and compactly on a window. When an instrument is created in the engineering builder, the instrument faceplate window automatically gets created depending on the type of the instrument. The Instrument Faceplate is used not only for monitoring but also for changing or setting of parameters and changing modes by operating the instrument faceplate. The figure below shows examples of various Instrument Faceplates.
The faceplates of the function blocks are classified into various display types. The display types are grouped according to their display characteristics. The display types are: • Analog type Such as PID controller block family. •
Discrete type Such as Three-Position Motor Control Block (MC-3), Switch Instrument Block with 1 Output (SO-1) and Batch Status Indicator Block (BSI).

6.1 Function Block Modes Block mode indicates the current mode in which an instrument is operating. There are different modes available for an instrument. • MAN (Manual) • AUT (Auto) • CAS (Cascade) • PRD (Primary Direct)
6.1.1Manual Mode (MAN) In this mode the instrument or function block needs to be manually operated. The manipulated value (MV) or set value (SV) can be changed by the user. In manual mode, the MV pointer appears in red colour and the SV pointer appears in yellow colour.
6.1.2 Auto Mode (AUT) In this mode the operator would provide the desired set point. The instrument would respond automatically to the PV changes based on the set point given by the operator and would generate the MV values. In Auto mode, the SV pointer appears in red colour and the MV pointer appears in yellow colour. While the SV of the instrument can be changed, the MV cannot be changed by any method in this mode.
6.1.3 Cascade Mode (CAS) In a cascade loop the output of the primary controller (MV1) goes as set point of the secondary controller (SV2). The output of the secondary controller (MV2) goes to the final control element. For a cascade loop, the primary controller can be in AUT or MAN mode, but the secondary controller has to be in CAS mode. In cascade mode both the SV and MV pointers appear in yellow color. Both the SV and MV cannot be changed.
TE Y109JA01E-VPOP
50
6.1.4 Primary Direct Mode (PRD)
In normal cascade mode the output of the primary controller (MV1) goes as set point of the secondary controller (SV2). The output of the secondary controller (MV2) goes to the final control element. In PRD mode the output of the primary controller (MV1) directly goes to the final control element. The secondary controller is bypassed and cannot be operated. The PRD mode can be set from the tuning view of the secondary controller.
6.1.5 Initialization Manual (IMAN) IMAN is not a mode status, but a mode sub-status. In a cascade loop, if the cascade is broken by taking the secondary controller from CAS to either AUT or MAN mode, IMAN appears as the mode sub status of the primary controller. IMAN indicates that • Cascade loop is broken • Primary controller is bypassed • Primary controller cannot be operated due to SV tracking. In SV tracking the output of the primary controller (MV1) automatically tracks the set point of the secondary controller (SV2) to have bump less transfer to CAS mode. The primary controller can be brought out of IMAN mode by changing the mode status of the secondary controller to CAS. The primary controller will automatically come out of IMAN mode and start functioning normally.

6.2 Function Block Alarm Status Alarm processing in a DCS can be classified into two types: • System Alarm • Process Alarm
System Alarm The system alarm notifies operator of the abnormalities in the hardware and communication errors. The type and contents of the system alarm are predetermined. Process Alarm The process alarm notifies operator of the occurrence and recovery of abnormality in the process. The type and contents of the process alarm are predetermined. When an alarm occurs, the alarm is indicated on the faceplate, tuning view, System Message Banner and is also listed in the Process Alarm View. It indicates a color change and an audible buzzer sound.
6.2.1 Process Alarm Status The table shows the list of process alarms that an instrument can have. It also indicates the settings required for the alarms and the color change when the alarm occurs. The settings for the process alarms can be set in the tuning view. ALARM STATUS

8.1 Contact Input Contact inputs are process inputs which handle ON/OFF signals such as DC voltages and currents. The ON/OFF signal is a digital value of either 0 or 1, which together with an indication of the quality of that value, shows the status of the process data item. Contact input modules are classified into the following two types according to the input signal. •Status input module Used for monitoring the status of contact inputs. ON/OFF status of input contact signals is used as the measured value (raw data). •Pushbutton input module Used for the input signal from pushbutton switches where the signal status change from ON to OFF or vice versa is momentary. Contact Inputs are used to indicate: • ON / OFF status of pumps, motors, heaters, etc. •
OPEN / CLOSE status of on-off valves.
The faceplate of contact inputs is as shown. The faceplates can be called from the Name Input Tool Box. The system code for contact inputs is: %ZnnusccSddss where, %Z - Process Input/Output nn - node number u - I/O unit number s - Slot number cc - Channel number S - Station dd - Domain number ss - Station number
TE Y109JA01E-VPOP
66 A potential free contact is taken from the equipment under operation in the field to indicate whether the equipment is running or not. In case of valve, contact is taken from limit switches to indicate whether the valve is open or close in the field at any point of time. These signals are wired as contact inputs to the system. When the digital input process value is 1, it indicates that physically the contact connected to the Digital Input card is closed in the field.
When the digital input process value is 0, it indicates that physically the contact connected to the Digital Input card is open in the field.
8.2 Contact Output Contact outputs are process outputs which handle ON/OFF signals such as DC voltages and currents. The ON/OFF signal is a digital value of either 0 or 1, which together with an indication of the quality of that value, shows the status of the process data item. Contact Outputs are used to: • Switch ON / OFF pumps, motors, heaters etc •
OPEN / CLOSE on-off valves.
TE Y109JA01E-VPOP
67
The system code for process outputs is: %ZnnusccSddss where, %Z - Process Input/Output nn - node number u - I/O unit number s - Slot number cc - Channel number S - Station dd - Domain number ss - Station number The faceplate of contact outputs is as shown. The faceplates can be called from the Name Input Tool Box. Each contact output is physically connected to a relay. This relay is in turn connected to the equipment or solenoid in the field. When the digital output process value is 1, the relay connected to the digital output is energized. Hence the equipment or the solenoid connected to the relay is energized. When the digital output process value is 0, the relay connected to the digital output is de-energized. Hence the equipment or the solenoid connected to the relay is also de-energized.
TE Y109JA01E-VPOP

8.3 Software Switches Software inputs/outputs are virtual inputs/outputs that are provided by the FCS’s internal software. These software inputs/outputs also called as internal switches are classified into: •
Common switches
•
Global switches
Switches are used to store intermediate variables in the interlocks. Switches are used for applications like Auto / Manual selection, pump selection, speed selection, bypass selection etc..
8.3.1 Common Switches
Common switches are internal switches used by various control functions to save the shared logical values in an FCS. The logical value of a common switch is not directly output to an external FCS, but are used by various control functions in an FCS for condition testing and status manipulation. The System Code for Common switches is: %SWxxxxSddss %SWxxxx - Switch number (0001 - 4000) dd - Domain number ss - Station number
Common switches with element number %SW0001 to %SW0400 are fixed as system switches. Common switches with element number %SW0401 to %SW4000 may be freely defined by users.
8.3.2 Global Switches A global switch is an internal switch with the same logical value on all stations in the same domain. The value of global switch assigned to the present station can be checked and defined from any application on a station. Up to 256 write-enable global switches can be assigned to each station. The System Code for global switches is: %GSxxxxSddss %GSxxxx - Switch number (0001 - 0256) dd - Domain number ss - Station number TE Y109JA01E-VPOP
69
The defined value is broadcasted to each station in the system via control bus scan transmission when data transfer to other stations is defined at Scan Transmission Definition on the FCS Constants Builder. The values of global switches are updated at the same time mostly on all stations in the system. The values are updated by 100 msec, which is fixed. With this function, status information can be transferred from one station to the control function of another station with very little delay.
8.4 Switch Instrument
The switch instrument block is a function block which is often used to start/stop motors and pumps and monitor or manipulate open-close state of the motoroperated valves. In most cases, this type of blocks is used in combination with the sequence table block (ST16, ST16E) and the Logic Chart Block (LC64). The faceplate of the SIO block is as shown. MV is the output signal of the SIO block and the command to the field instrument. PV is the answerback signal received from the field to the SIO block.
8.4.1 SIO Normal Operation The normal operation of SIO is as explained. When MV=2, the DO is ON, the output relay is energized. The equipment connected to the relay is ON. The answerback DI is taken from the contact of the equipment. Since the equipment is ON, the contact closes. So the DI is ON, then PV becomes 2.
TE Y109JA01E-VPOP
70 When MV =0, DO is OFF, the output relay is de-energized. The equipment connected to the relay is OFF. Since the equipment is OFF, the answerback contact opens. So the DI is OFF, then PV becomes 0.
Alarm Status is NR in the above conditions.
TE Y109JA01E-VPOP
71 8.4.2 SIO Abnormal Operation (ANS+)
Let us consider the abnormal operation of the SIO. When MV=2, the DO is ON, the output relay is energized. The equipment connected to the relay is ON. If the answerback DI is not ON, then PV=0, SIO generates an ANS+ alarm automatically. This alarm is displayed in the System Message Banner and recorded in the Process Alarm View.
8.4.3 SIO Abnormal Operation (ANS-)
When MV=0, the DO is OFF, the output relay is de-energized. The equipment connected to the relay is OFF. If the answerback DI is still ON, then PV=2, SIO generates an ANSalarm automatically. This alarm is displayed in the System Message Banner and recorded in the Process Alarm View.

10.1 Concept of Trend View
The Trend view can be used for displaying various graphs of process data changed along with time axis. The change of process data with respect to time is referred to as trend data. On a Trend view, up to 8 trends of process data can be displayed.
10.1.1 Structure of Trend Recording By using the Trend Recording function, process data such as temperature, pressure and flow rate coming into the Control Station are gathered by the HIS, and the time-series changes in the process data are displayed as a graph (trend graph). The trend recording consists of: • Trend data acquisition • Trend data display • Closing processing
The Trend Recording has a three-layer structure: • Trend Block • Trend Group • Trend Pen Acquired trend data can be displayed as graphs in the Trend View and the Trend Point View. CENTUM VP provides for up to 50 blocks of trend per HIS. Each block in turn consists of 16 groups or 16 trend views. Under each group, up to 8 trend data can be assigned. Thus the trend data for up to 6400 pen can be recorded.
TE Y109JA01E-VPOP
82 TREND BLOCK The type of trend data acquisition and sampling period are specified for each trend block in the builder. Of the 50 trend blocks, 26 blocks can be defined as the trend format of “Continuous-Rotary Type”, “Batch-Stop Type” or “Batch-Rotary Type”. The remaining 24 trend blocks can be defined as the reference of the trend data acquired by other HIS. TREND VIEW Eight pens of trend data can be assigned to a Trend View. A trend block has 16 trend views.
TREND POINT VIEW The Trend Point view is called up from the Trend View and displays data for a single trend pen.
TE Y109JA01E-VPOP
83 10.1.2 Trend Format Trend data acquisition can be specified for the following 4 types: •Continuous-Rotary Type •Batch-Stop Type •Batch-Rotary Type •Other-Station-Reference type (Other Station Acquisition Trend) Continuous-Rotary Type In this type, the trend data are acquired constantly. After the HIS is started, the data acquisition is started automatically and continued until the HIS is shutdown. The acquired data will be retained even if the HIS is shutdown.
After the maximum number of samples is reached, the data acquisition continues by overwriting the oldest data with new data. Batch-Stop Type Using this type, trend data acquisition starts and stops according to the received commands. If no stop command is received, the data acquisition will stop automatically after acquiring the maximum number of samples. Batch-Rotary Type Using this type, trend data acquisition starts and stops according to the received commands. Once started, the data acquisition continues until a stop command is received. If the maximum number of samples is reached before receiving a stop command, older data are overwritten with new data.
TE Y109JA01E-VPOP
84 Other-Station-Reference Type (Other Station Acquisition Trend) Using this type, the trend data acquired by other HIS are referenced in trend block units.
10.1.3 Sampling Period The sampling period of trend data is defined for each trend block in the Properties sheet of the Trend Acquisition Pen Assignment Builder. The sampling period for the trend blocks can be: • 1 second • 10 seconds • 1 minute • 2 minutes • 5 minutes • 10 minutes The number of trend blocks that can be specified for the sampling periods of 1 minute, 2 minutes, 5 minutes, or 10 minutes is 18 in total. The number of trend blocks that can be specified for the sampling periods of 1 second or 10 seconds is 8 in total.
10.1.4 Recording Span The Recording Span is determined by the specified sampling period. The recording span is the time taken to acquire data for the maximum number of samples with the specified sampling period. The maximum number of samples is 2880 (fixed). The total recording span for each sampling period is as shown in the table.
