10. LABORATORY EXERCISES

PART A - REGULATORY CONTROL EXERCISES

A1. Dual Redundant Input Exercise Objective: The purpose of this exercise is to gain an understanding of how the SS-DUAL module is used to provide dual redundancy where two field transmitters are used. Description: Two flowmeters are input into the DCS and are registered as PVIs. These connect to a SS-DUAL to select one of the two for output. Procedure:

1. Hardwire the outputs in channels 3 & 4 to the input in channels 1 & 2, of the analog nest.

2. In a control drawing, connect the two analog inputs to two PVIs, and then into

and SS-DUAL. The output of the SS-DUAL connects to another PVI. 3. Drive the two outputs with two Manual Loaders. Tags names are as follows:

Tag name Description Module %Z011101 Input 1 %Z011102 Input 2 %Z011103 Output 1 %Z011104 Output 2 FI100A Input Indicator 1 PVI FI100B Input Indicator 2 PVI FI100DV Input Selector SS-DUAL FI100 Selector Input Indicator PVI CV100A Output Loader 1 MLD CV100B Output Loader 2 MLD

A2. ID FAN Flow/Pressure Control Switching Exercise Objective: This exercise in regulatory control provides an example of a common control application of flow/pressure control switching using different techniques that can be employed using function blocks and control drawings. It demonstrates how an inlet draft fan can be controlled according to flow and pressure. Description: The speed of a draft fan is controlled by the DCS based on either the flowrate or the pressure of the incoming air. At low fan speeds, the fan speed is controlled by pressure. At higher speeds, the control switches to flow control. The DCS reads the pressure and the flowrate as analog inputs, into PVIs. These feed into two standard PID controllers. The outputs of these controllers are fed to a high selector switch (AS-H) which selects the higher of the two outputs for control. This signal goes through an MLD-SW for operator control and then output to the fan drive speed controller as a 4-20mA signal. When the MLD-SW is in manual, the controllers are forced into track mode. Procedure: The attached control scheme shows how the requirements above can be achieved. Note that due to the in-built “pushback” feature of the system, the controllers track the manual loader when it is in manual. No tracking wiring is required. Note that the AS-H was used, rather than the SS-H. This is because the input to the MLD-SW is a SET, and therefore a Cascade input. Because of the way the “pushback” feature works, the preceding module must have an MV through the OUT terminal. The AS-H has this, whereas the SS-H only has a PV, and therefore cannot be used in a cascade loop. Module Details: 1. FI3001 Flowrate PVI Range: 0 to 150 M3/M 2. PI3001 Pressure PVI Range: 0 to 350 KPA 3. FIC3001 Flow Controller PID Range: 0 to 150 M3/M 4. PIC3001 Pressure Controller PID Range: 0 to 350 KPA 5.

Set up a Control Group called IDFAN, with all of the tags in it. Call up IDFAN on the operator display and set up the function blocks as follows:

FD3001 - set to AUT SFD3001 - set to AUT - set SW = 4 PIC3001 - set to AUT - set SV = 250 FIC3001 - set to AUT - set SV = 100

Vary the set points such that the MVs of the blocks move up and down. Notice how the greater of the two MVs is the one selected for output. Put FD3001 into MAN and change its output. Notice how this value is pushed back to the preceding blocks, both the SFD3001 and the controllers. All of these blocks are in IMAN and are tracking this value. Test Function If test function is already running, then the wiring between the inputs and outputs will not have been done. TO set this up, do the following procedure.

1. In the Test Function Panel, click on the Tools menu and select Wiring Editor 2. Select Tools Auto-Wiring (at the bottom of the menu). Select DR0002. 3. Select File Open and select DR0002. 4. Select File Download.

A3. Ratio Control Exercise Objective: The purpose of this exercise is to learn how to use the Ratio block to perform ratio control. Description: The flow controller controls the additive flowrate. The setpoint to this controller is from a RATIO control block, and its input is the main flow. The operator sets the SV of the RATIO block to (say) 0.1, so that the setpoint of the flow controller is 0.1 of the main flow. Procedure: The attached control scheme shows how the requirements above can be achieved.

The MLD FI201 simulates the main line flow, and this can be adjusted by the operator accordingly. The LAG block simulates the dosing flow. To set the lag time of the block, set the I value to around 5 seconds. Set the setpoint of the ratio block (FR200) to 0.1. Set FIC200 to CAS. Thus the setpoint to FIC200 will be a tenth of the flow from FI201.

A4. Temperature Profile Control Exercise Objective: The purpose of this exercise is to learn how to use the PG-L13 block to perform temperature profile control. Description: The flow controller controls the temperature of the process. The setpoint to this controller is from a PG-L13 block, and the profile created by the PG-L13 block will drive the setpoint of the controller. Procedure: The attached control scheme shows how the requirements above can be achieved.

Set up the TQ200 in the tuning panel as follows:

X01 = 0 Y01 = 0 X02 = 30 Y02 = 50 X03 = 45 Y03 = 50 X04 = 70 Y04 = 85 X05 = 95 Y05 = 85 X06 = 120 Y06 = 0

Set ZONEND = 5 Set TIC200 to CAS Set TQ200 to AUT The PG-L13 should now run through its program defined by the X, Y values given above. The X values are time in seconds, and each value represents the time from the beginning, not from the previous zone. Set TQ200 to CAS. In this case, the program loops around continuously.

A5. Boiler Level Control Objective: The purpose of this exercise is to learn how to use standard control functions to perform complex boiler control. Description: The boiler level is to be maintained by level/flow cascade control with feed forward where the steam flow demand adjusts the requirements for the boiler. The level is a duplicated field transmitter signal, monitored by an SS-DUAL. The output is split to two feedwater control valves.

PART B - CALCULATION FUNCTION EXERCISES

B1. Boiler Control Simulation Exercise Objective: This exercise uses calculation blocks to provide simulation of the boiler level, based on the above exercise. Description: The difference between the feedwater flow into the boiler and the steam flow out of the boiler is calculated in an ADD module. The result of this is input to a INTEG module to sum the deviation. This is the simulated level and the output is input to the two level input blocks. Procedure:

1. To set up a simulated flow loop, add the following blocks:

ADD (FQ105) - Input 1 (IN) = MV of CV105A - Input 2 (Q01) = MV of CV105B

LAG (FT105) - Input (IN) = CPV of the ADD module - Output (CPV) = IN of FI105

Setup the LAG block with I = 5. 2. To create a simulated level, add the following blocks:

ADD (LA105) - Input 1 (IN) = the PV of FI105 - Input 2 (Q01) = the PV of FI101 INTEG (LQ105) - IN = the CPV of the ADD module - CPV = IN of the two level PVIs (LI105A/B)

3. Setup the ADD block with the GN1 = -1, so that it subtracts the inputs.

4. Set the I of the INTEG block to 30 so that the level changes slowly.

B2. Numerical Calculations

Numerical blocks are ADD, MULTIPLY, DIVIDE and AVERAGE. They all have similar functions, and this exercise investigates the ADD block in detail as an example of each of numerical blocks.

Connect two MLDs to an ADD block. Connect the output of the ADD block to another PVI. Set the following parameters in the tuning panel:

GAIN = 1 BIAS = 0 GN1 = 1 BS1 = 0

Note that the result of the ADD is the sum of the two inputs. Try varying the GAIN and BIAS and look at the effect on the final value. The GN1 and BS1 are a gain and bias on the second input. Set the values as follows:

GN1 = -1 BS1 = 0

Note that the result of the ADD is the difference between the two inputs. This is how this module is used as a subtractor. A common application is for the second input to be a +/- trim on the first input. So, if the first input is 0-100%, and the second input is also 0-100%, but it is required that the second input trim the first by -50 to +50%, set the parameters as follows:

GN1 = 1 BS1 = -50

What would you set these values to, to trim the first input by +/-20%, when the second input is 0-100%?

GN1 = 0.4 BS1 = -20

B3. Analog Calculation Blocks Analog calculations are single input blocks that provide a calculation function on this input. Most are self explanatory, but some of the more used blocks will be discussed here.

♦ LAG

Connect an MLD block to the input of a LAG block. Connect the output of the LAG block to a PVI. On the operator display, move the value in the MLD block and observe the corresponding value on the PVI. In the tuning panel of the LAG block, note that there is a data item called I. This is the time constant of the LAG block. The greater this value, the more lag there is between output and input. Try increasing this and changing the MLD, monitoring the corresponding change on the PVI. Note that as well as the I item, there is also a GAIN item. This is a multiplier on the output. Set this value to 2 and see what happens to the output.

♦ INTEG - Integration Block

This block is a totaliser, that is, it sums the input over time. The integration can be started and stopped with the SW item.

Connect an MLD to an INTEG block and monitor the integration on the operator display. Note the following data items:

I GAIN

The I is used to set the time base of the integration. For example, if the input being totalised is in:

L/sec, then I = 1 sec/sec L/min, then I = 60 sec/min L/hr, then I = 3600 sec/hour

Try setting the I to different values and monitor the change in speed of integration. The GAIN is used as a multiplier on the output. Try setting the GAIN to different values and monitor the change in output. Set the SW to 2 and then 1. The totaliser will stop and then continue without resetting. Set SW to 0. The totaliser will reset and then continue, with the SW automatically returning to 1.

♦ AVE-M

The moving average can be used as a more sophisticated form of smoothing of an input.

Connect an MLD to the input of an AVE-M. In the tuning panel, set the following data items:

SMPL = 1 (the sampling rate in seconds) NUM = 10 (the number of samples that are being averaged)

Change the input value by adjusting the MLD output, and monitor the change in the AVE-M calculated value (CPV). Change the SMPL to 2 and monitor the changes again. The number of sampling points and the sampling interval can be changed to dampen the input signal in different ways.

♦ FUNC-VAR

The Function block provides a free-form function to be applied to an input.

Connect an MLD block to the input of a FUNC block. Set the X,Y parameters in the FUNC block tuning panel to different values and monitor the result.

X1 = 0 Y1 = 0 X2 = 10 Y2 = 20 X3 = 20 Y3 = 35 X4 = 30 Y4 = 70 X5 = 40 Y5 = 80 X6 = 50 Y6 = 85 X7 = 60 Y7 = 75 X8 = 70 Y8 = 50 X9 = 80 Y9 = 20 X10 = 100 Y10 = 0

SECT = 9

B4. Setpoint Setting This exercise uses some of the Calculation modules to set the setpoint of a controller.

Create the following function blocks:

Tagname Block Type DATA01 DSW-16 RAMP01 RAMP SWITCH2 SW-33 SET01 DSET TIC500 PID LG01 LAG01

These are to be connected as follows:

When this is compiled and loaded, set the following tuning parameters:

DATA01 RAMP01

SD01 = 0 STEP = 100 SD02 = 10 SD03 = 20 SD04 = 30 SD05 = 40 SW = 1

___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-16

Operation:

• Set TIC500 to CAS • Set SWITCH2, SW = 1 • In DATA01, set SW = 2

Its output will increase from 0 to 10, and the output of the ramp block will ramp up from 0 to 10. The should be transferred to the PID block for it to control to. Set the SW in DATA01 to different switch values and notice how the set point in the controller changes accordingly. In SWITCH2, set SW to 2. The set point is now set by changing the SV in the DSET.

B5. Calculation Exercise Objective: To learn how to build a CALCU to perform arithmetic functions. Description: This exercise is in four parts:

• The first part reads 3 inputs, performs a calculation on it and writes the result to the first output (CPV).

CPV = (RV + RV1 * P01 ) / (RV2 + P02) • The second part selects the maximum of the 3 inputs and writes the

result to the second output (CPV1). • The third part loads RV into CPV2 if RV1 > RV2. • The fourth part averages all or some of the inputs depending on the

status of three selection switches (%SW). If one switch is on, the related input is loaded to CPV3. If two switches are on, the two related inputs are averaged

and the result is loaded into CPV3. If three switches are on, all inputs are averaged and the

result is loaded into CPV3. Procedure:

PART C - SEQUENCE TABLE EXERCISES

C1. Global Switch Exercise Objective: The purpose of this exercise is to provide an understanding of how Global Switches work across a network. Description: The sequence in FCS01 waits for Global Switch 1 in FCS02 to turn on. When it is on, it turns the local Global Switch 1 off. When the sequence in FCS02 sees that Global Switch 1 in FCS01 is off, it turns the local Global Switch 1 off. When the sequence in FCS01 see that Global Switch 1 in FCS02 is off, it turns the local Global Switch 1 on. Thus the Global Switches toggle each other. Procedure: Create 2 sequence tables, 1 in each of FCS01 and FCS02 as follows: ST16 - FCS01, Tag= GLOBAL1 ST16 - FCS02, Tag=GLOBAL2 %GS00102.PV 1 Y N %GS00101.PV 1 Y N

%GS001.PV H N Y

%GS001.PV H Y N

C2. Mode Setting Exercise Objective: The purpose of this exercise is to explore the uses of mode setting in a

controller from a sequence table. Description: This exercise makes use of the cascade controller exercise (Tutorial

D2). If there is a problem with the input to the flow controller, then force it into PRD so that the primary controller is controlling through it. If the temperature controller (TIC100) goes into HI alarm, then force it into manual and set the output to zero.

Procedure:

1. Create a common switch, tagname: IOPALRM 2. Open DR0001 where the cascade control loop is. 3. Add a sequence table (ST16), tagname: SEQ100 4. Enter the following logic into it:

C01 C02 C03 C04 C05 C06

IOPALRM.PV TIC100.ALRM

ON HI

Y N

A01 A02 A03 A04 A05 A06

FIC100.MODE FIC100.MODE TIC100.PSW TIC100.MODE

PRD CAS 1 AUT

Y Y

Y

Y

Note: Because we cannot simulate a BAD input, the tripping of FIC100 to PRD is done by creating a switch call IOPALRM and turning this on manually.

Operation:

5. Call up FIC100, TIC100 and IOPALRM. 6. Make sure that FIC100 is in CAS and TIC100 is in AUT. 7. Turn on IOPALRM. Note that FIC100 goes to PRD, and the output is set by

the output of TIC100. 8. Set the PH of TIC100 to 70, and set its setpoint to 80. Every time it goes into

HI alarm, it is forced to manual and the output is set to zero, causing it to go back into AUT.

C2. Pump Interlock Exercise Objective: This is a practical exercise that uses a timer and counter to limit the number of pump starts in a given period. The objective is to learn how to use timers and counters. Description: The sequence counts the number of starts made by a pump. If the maximum number of starts are exceeded within a time period, the start command is interlocked so that no more starts can be made and an alarm is sounded. When the timer expires, the counter is reset. Procedure:

1. Create 2 Common Switches to simulate the pump:

P1START Operator Request P1CMD Start Command from Sequence

2. Create Annunciator Message

Tag = P1INT Message = Pump1 Interlock

3. Create an Operator Guide

%OG0001 Message = The Pump interlock is cleared

4. On a new Control Drawing:

Comment = Pump1 Control Create: Timer (TM) - P1TM Counter (CTS) - P1CT Sequence (ST16) - P1CTL

5. Sequence Table Logic:

C01 C02 C03 C04 C05 C06

Sequence Operation:

1. Create a Control Group with the following tags on it:

• P1START • P1CMD • P1INT • P1TM • P1CT • P1CTL

2. Put the sequence table into AUT 3. Set the PH of P1TIM (the timer) to 60 4. Set the PH of P1CT (the counter) to 5 5. Turn on P1START. P1CMD will come on and the counter will increment. 6. Turn off P1START. P1CMD will turn off. 7. Repeat this 5 times. The alarm will sound (P1INT will go on). 8. When you try to turn it on again, P1CMD will stay off. 9. When the timer reaches 60, the counter will be reset and the Operator Guide

will come on to indicate that the interlock is cleared.

C3. Relational Expression Exercise Objective: This exercise shows how to compare analogue values in a sequence. Description: A Manual Loader is used to generate an analog value. If the value goes above 75.0 or below 25.0, then an alarm is generated using Annunciators:

If MLD > 75.0, Set Alarm 1 If MLD < 25.0, Set Alarm 2

The set points are stored in a BDSET and are set through the operator display. Procedure:

1. Create the following function blocks in a control drawing:

MLD - VSET RL - VCMP ST16 - VSQ BDSET-1L - VDATA And register the following annunciators: VALRM1 - comment = “High Alarm” VALRM2 - comment = “Low Alarm”

2. In the RL Block, go to EDIT DETAIL, and enter the following:

VSET.MV CMP VDATA.DT01 VSET.MV CMP VDATA.DT02

3. Sequence Table logic:

C4. Sequence Exercise Using Switch Instrument Block Part 1 Objective: The purpose of this exercise is to learn how a switch instrument block works, and how to control it from a sequence table. Description: A pump with isolation valve is used to fill a tank using the following logic:

If tank level is low: Put valve and pump into Auto Open Valve

When valve is open: Start pump

If Level is high:

Put valve and pump into Auto Stop Pump

When pump is stopped: Close Valve

Procedure: 1. On a Control Drawing, create the following modules:

Tagname Description Module BFP1 Pump Control Block MC-2 BFV1 Valve Control Block SIO-11 BLI1 Level Indicator PVI BLI1-M Level Simulation MLD LVLCTL Pump Sequence Control ST16

2. To set up the pushbutton labels on BFP1, select the block, and right-click, select

EDIT DETAIL. In the BASIC tab, set the Switch Position Label to RUN,,STOP,RUN. In the INPUT tab, set the Answerback Check to BOTH SIDES. This can also be done for the valve (BFV1).

3. Register four consecutive Common Switches to act as contact I/O for the Pump

Control Block, with the following tag names:

%SW1001 BFP1-RUN Run Feedback %SW1002 BFP1-STP Stop Feedback %SW1003 BFP1-START Start Command %SW1004 BFP1-STOP Stop Command

4. Link the BFP1-RUN switch into the IN terminal of BFP1, and connect the OUT

terminal to BFP1-START. Note that BFP1-STP and BFP1-STOP are automatically linked when the software is downloaded.


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-29

5. Connect the MV of BLI1-M to the IN terminal of BLI1. 6. Configure the sequence table according to the sequence described above. 7. Setup: Put the tags into a control group. In the Operators panel, go to the

tuning panel for the Pump control faceplate (BFP1) and set the SIMM = 1. Do the same for BFV1. Set the high and low alarm levels in BLI1 to 75% and 25%.

8. Put the sequence into AUT and raise the MLD value to above 75% and observe

what happens to the pump. Lower it to below 25% and observe the pump starting. Part 2 - I/O Simulation Objective: Provide simulation for the Pump I/O. This provides learning in how to drive and monitor switches from a logic chart. Description: If the BFP1-START switch is on, switch on BFP1-RUN. If BFP1-STOP switch is on, switch on BFP1-STP. Use On Delay timers (OND) to simulate lags in the process. Procedure:

1. Create a new Logic Chart on the control drawing, with tag name: BFP1IO. Put in the logic as described above.

2. In BFP1, set SIMM = 0. 3. Confirm its operations by running it in Manual.

Part 3 - Using the Motor Control Module (MC-2) Objective: To learn how the MC-2/3 works and the differences between it and the SIO module. Description: Add an analog feedback for pump speed, and TRIP and INT contacts. Procedure: 1. Create a Manual Loader (MLD) with tagname BFP1-SPEED, and wire it into the

FB terminal of the MC-2 2. Create two Common Switches with tagnames: BFP1-INT and BFP1-TRIP and

connect to terminals IL and TT of the MC-2 3. Add these extra modules to the control group for display.

C5. Boiler Fill Sequence Exercise Objective: To learn how to use the step feature of the sequence table. Description: This is a boiler fill sequence which contains a monitoring step, and a sequence of steps. The step sequence is as follows:

Step 1 - Conditions: Burner Off (*1) Deaerator Level >= NWL (normal water level) Deaerator Temp < 70 Deg C Boiler Level <= NWL Operator Start Request - Actions: Open Feedwater Regulating Valve full open Start BFP Lube Oil Pump Goto Step 2 Step 2 - Conditions: If Lube Oil Pump running for 1 minute - Actions: Start BFP Goto Step 3 Step 3a - Conditions: If boiler level >= NWL - Actions: Set Boiler Ready switch and operator guide Start Burner (*1) Set Feedwater Control to CAS Step 3b- Conditions: If Deaerator Level Low - Actions: Trip BFP Stop Lube Pump Goto Step 1 Step 00 (continuous monitoring step) - If Boiler Level High - Trip BFP - If DA Level Low - Trip BFP - If Boiler Level Low and Burner is on - Stop Burner - If Lube Oil Pump Stopped - Trip BFP in all these cases, force the step to A1.

Use the boiler level control drawing and the boiler feed pump drawing for the existing tags. Create a manual loader and PVI loop to simulate the Deaerator level and temperature. (*1) For burner, use a Common Switch which should be off at the beginning of the sequence and is turned on in step 3.

PART D - TUTORIALS

D1. System Configuration In this tutorial, we will learn how to set up a project, and create & edit control stations within the project. This will involved the following steps: 1. Create a new project 2. Define hardware devices 3. Define field I/O 4. Define PLC communications


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-32

1. Create a New Project To create a new project:

Click on SYSTEM VIEW within the System View window

Either: Click on FILE CREATE NEW PROJECT Or: Click on SYSTEM VIEW with the right might button and select

CREATE NEW PROJECT

Click OK


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-33

A new window appears. Enter the information as follows: Project: TRAINING (or any name, uppercase, 8 characters or less) Position: C:\CS3000\ENG\BKPROJECT Click on the ‘Constant’ tab and enter the number of domains. In this case, enter 1.

Click OK.


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-34

This creates a new project, and a dialog box appears to create a new FCS.

Enter the Station Type (AFG30D) and the Station number and click OK. A new FCS is created. The Create New HIS dialog box appears next:

Enter the above information and click OK. A new HIS is created. The project creation procedure is now complete. Notice that an FCS and a HIS are created automatically when the project is created.


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-35

2. Define Hardware Devices The properties of the existing hardware devices can be edited, and new hardware can be created. 2.1 Creating and Editing the FCS

To edit the properties of an existing FCS, click on it with the right mouse button and select PROPERTIES. The same dialog box appears as when a new FCS is created, except that certain options are grayed out. Note which items cannot be changed once the FCS is created. The are two ways of creating a new FCS:

1. Select CREATE NEW FCS from the FILE menu. This creates a new FCS for the project. Note that the station address is incremented by 1. 2. Click on an existing FCS and drag it upto the project name. This

copies the FCS and all it's properties and contents to a new FCS. Note that the properties of this FCS are the same as the FCS it was copied from and cannot be changed.

2.2 Creating and Editing the HIS

To edit the properties of an existing HIS, click on it with the right mouse button and select PROPERTIES. The same dialog box appears as when a new HIS is created, except that certain options are grayed out. Note which items cannot be changed once the HIS is created. The are two ways of creating a new HIS:

1. Select CREATE NEW HIS from the FILE menu. This creates a new HIS for the project. Note that the station address is decreased by 1. 2. Click on an existing HIS and drag it upto the project name. This copies the HIS and all it's properties and contents to a new HIS. Note that the properties of this HIS are the same as the HIS it was copied from and cannot be changed.


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-36

2.3 Creating and Editing the BCV (Vnet – Vnet)

There is only one way of creating a new BCV:

1 Select CREATE NEW BCV from the FILE menu.

This creates a new BCV for the project. Select the CONSTANT tab and select a Domain number of 2 (or any number up to 16), and a station number (1-64) for the lower address. The BCV is connected to two networks (domains), and so the address must be set up for both networks on which it resides. Note that the station address is increased by 1 from the previous FCS or BCV. A BCV cannot be copied.

To edit the properties of an existing BCV, click on it with the right mouse button and select PROPERTIES. The same dialog box appears as when a new BCV is created, except that certain options are grayed out. Note which items cannot be changed once the BCV is created.


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-37

2.4 Creating and Editing the BCV (Vnet – RL Bus) Before a Bus Converter for uXL can be created, the stations in the uXL domain must be specified in the project so that a tag-list can be generated for the bus converter. To create a uXL station in the project:

1. Select CREATE NEW STATION from the FILE menu. 2. Select the uXL station type (eg MFCD-EXT). 3. Set the domain (17 or above) and the station address. 4. Click OK. A folder is created with the name STNddss

where: dd = domain number for the uXL system ss = station number for the MFCD on the RL bus.

5. Open the STN folder (click on the +) and click on the TAGLIST folder. Three

files will appear on the right hand side. These are:

TFDATA - List of function blocks, etc in the MFCD OGDATA - Operator Guides in the MFCD SMDATA - Sequence Message Requests in the MFCD

Double click on the TFDATA file to open the following page:

Enter a Tagname, Function Block Type, and Tag Comment as shown above. Select File Save note: If the TFDATA file does not contain any tag information then the Vnet –

RL Bus Bus converter will not compile.


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-38

The tag information can be manually entered or imported as a CSV file. To import a CSV file, select: FILE EXTERNAL FILE CSV FILES IMPORT. The following box appears:

Select those items to be imported, and the name of the CSV file. Note: at this stage you will have nothing to import, so CLOSE this dialog. Double click on files OGDATA and SMDATA and Save and Exit these. This is necessary to create the files, even though there is nothing in them. Once the Stations have been defined, the Bus Converter can be created. To create a new RL Bus Converter:

1. Select FILE CREATE NEW BCV. 2. Select Bus Converter for RL Bus. 3. Set Domain and Station number for the Vnet side. 4. Click on the Constant tab and set the domain and station number for the RL

bus side. Domain will be 17 or greater. 5. Click on the Lower Station tab and there should be a list of all the uXL

STATIONS defined in that domain in the project. Check those ones that are to be included in the Taglist (usually all of them).

6. Click OK (there is nothing to set in the Lower Gateway Definition tab). The Bus Converter is now created. When it is downloaded, the taglists from the associated uXL stations are included in the download. Note that an offline load is required every time a new tag is added. This stops the Bus Converter. If a tag is modified, rather than added, then an online load can be carried out.


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-39

3. Define I/O - FIO I/O resides in each of the FCSs and is located in the IOM folder. Within the IOM folder are up to 10 NODE folders, and within each of these reside the files for each I/O card. 1. Expand an FCS folder by clicking on the + next to it. 2. Click on the IOM Folder. Currently there are no NODE folders in it. 3. Right Click on the IOM folder and select CREATE NEW NODE.

4. Select a local node, with an address of 1. It does not matter whether Dual-

Redundant Power Supply is selected or not.


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-40

5. Click on the NODE folder with the right mouse button and select CREATE NEW

IOM. The following window appears:

6. Creating Analog I/O

- Select Analog Input/Output under Category - Select AAI841-S under Type - Select Slot =1 - Click OK

This creates an analog I/O module file in slot 1 on the node. The file name is 1AAI841-S (ie, Slot 1, Type AAI841-S). To configure I/O points within it:

- Double click on the file. The I/O definition window appears. - The I/O is in fixed positions (Inputs are 1 – 8 and Outputs are 9 – 16). - Click Save and then FILE EXIT

This can be edited later at any time by double clicking on this file.

7. Creating Digital Inputs

- Repeat step 5 to create another IOM - Select Category = Status Input. Pushbutton input can also be selected. - Select Type = 32-Channel Status Input (ADV157-S). - Select Slot 2


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-41

- Click OK - Double click on the new file (2ADV157-S) - Details for all 32 points point are available here - The most important field is TAGNAME. If a tag name is configured here,

then the system recognises the digital input by that name. - Select FILE EXIT

- Repeat step 5 to create another IOM - Select Category = Status Output - Select Type = 32-Channel Status Output(ADV557-S). - Select Slot 3 - Click OK - Double click on the new file (3ADV557-S) - Details for all 32 points point are available here, including Tag name

setting. - Select FILE EXIT

8. Creating a Remote Node

A remote node cannot be created until an ER Bus Interface module (EB401) is configured in a local node. Once this is created, up to 9 remote nodes can be connected to this one module. Note that this maximum of 9 is limited by the overall maximum of 10 nodes for the FCS. Create a Bus Interface module in the Local Node:

- Right click on a local node (in this example, Node1) - Select Create New IOM. - Category = Remote Node Communication - Type = EB401 (ER Bus Interface Module) - Slot = 5 - Click on “Duplicate Next Card” as it is normal (but not mandatory) to have

dual redundant communications to the remote nodes. - Click OK, and the two cards (EB401 and EB401Dup) will appear.

Create a Remote Node connected to this Bus Interface card:

- Right click on IOM and select Create New Node - Select Remote Node and choose the EB401 module you have created from

the drop down list. Unless you have created more in other nodes, this module will be the only one on the list.

- It is recommended that the IP address is left on default and not changed. - Click OK.

This new node is a remote node connected to the EB401 module created above.


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-42

4. Define PLC Communications PLC Communications are defined in the same way as process I/O is defined.

- Right click on NODE 1 and select CREATE NEW IOM - Select Category = Serial Communication - Select Type = RS232C Serial Communication Interface (ALR111) - Select Slot = 4 - Click on the CARD COMMON tab - Select Connection Device = MODBUS - Click on the Port 1 tab - These are the communications settings for the first port. These can be left on

default, or set as needed. - Repeat for Port 2 - Click OK

A new file called 4ALR111 is created, where the number at the beginning is the slot number. To define the I/O points to be transferred between the card and the PLC, double click on the file. For this exercise, we are going to set up a Modbus communications link to a PLC, reading and writing the following I/O:

10 Analogue Inputs 64 Digital Inputs 5 Analogue Outputs 32 Digital Outputs

The entry fields are configured as follows:

- Buffer Size - Enter a value (say 100) to define the overall size of the data to be transferred with this ALR111 card.

• Note that this is in number of Words (= 16 bits).

- The number of analogs to a word varies on the size of the analog. A 32 bit analog is 2 words in size.

- There are 16 digitals to one Word. • For Modbus, there is a maximum of 500 words for one communications

card. - Program Name - select the device driver selected when defining the module

properties (K1-1-4MODBUS – i.e., the Modbus communications card in slot 4 of Node1).

This actually specifies the card being used in this part of the I/O definition. The same definition table is used for the whole FCS.

- Data Size - Specify the data size in words for this block of data. Enter 10

words for the analogue inputs.

- Port Number – an ALR card has two ports on it. Specify which port you are communicating through. In this case, set Port = 1.


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-43

- Station Number and IP address – for an ALR card, only the station number is

relevant, and this is usually a number between 1 and 128 that is an address set within the PLC. The IP address is used if this is an ALE card. For now, set the Station Number = 1 and leave the IP Address blank.

- Device & Address depend on the PLC in use. In this case it is Modbus (see

section 5.7.4), so for analogue inputs, enter A30001. That is, we are reading 10 analogue inputs starting from input 1 in the PLC.

- Data Type – Select Input (16 bit signed). This tells the FCS that this block of

data is an input to the DCS, i.e., it is being read by the ALR111. It is also telling the FCS to convert the word to a 16 bit analogue value. Input processing in PVIs and PIDs can convert this to a real number. If the analogues being read are 32 bit, then 1 analogue value would use 2 words.

Repeat this procedure for the other inputs and outputs as follows:

Size Port Address Device & Address Data Type 10 1 1 A30001 Input (16 bit signed) 4 1 1 A10001 Input (Discrete) 5 1 1 A40001 Output (16 bit signed) 2 1 1 A00001 Output (Discrete)

Select File Save


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-44

Points to note: 1. For the Discrete I/O, the Data Size (being in 16 bit words) is the number of digitals divided by 16. So, in the above example, 4 words of Digital Inputs represented 64 DI, and 2 words of Digital Outputs are 32 DOs.

2. The system uses an even number of packets for Data Size, so when 5 analogue outputs are selected, 6 are configured.

Configuring Tagnames for Digital I/O:

It is possible to give the digital I/O tagnames so that they can be referenced in the system by recognisable names, rather than system numbers (E.g. %WB000107). Up to 1000 tagnames can be assigned. Any that are not assigned a tagname can still be addressed by its system name. To understand how this works, it is necessary to understand how digitals are extracted from words. In the above example, words 11 – 14 contains 4 words of Digital Inputs, i.e., %WW0011 to %WW0014. Within %WW0011 are 16 bits and these are addressed as follows: %WB001101 to %WB001116 In other words, bits 01 to 16 from Word 11.

In the communication I/O builder, click on TOOLS “Call %WB Tag Number Definition”. There are two fields that need to be configured: Element – enter the system number of the bit being assigned a number, e.g. %WB001107 Tagname – enter the required tagname for this system number. All the other parameters are optional and are the same as configuring Digital I/O and common switches.

D2. Creation of Regulatory Control Function In this tutorial we will learn how to create a control application using a cascade loop as an example. This exercise assumes that the previous tutorial has been completed, and the following I/O card has been configured:

Node1, Slot1 – Create an analogue input/output module, e.g. AAI841-S


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-46

1. Starting the Control Drawing Builder

• Start System View and open the required FCS. • Left Click on FUNCTION_BLOCK • Double Click on DR0001 in the right-hand pane.

The Control Drawing Builder appears:


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-47

2. Drawing the Function Blocks

We are going to place two PIC function blocks on the control drawing: TIC100 and FIC100, and three PIO Link blocks to connect the Process I/O to the inputs and outputs of these blocks.

To call up the Function Block selection menu either:

• Insert Function Block • or click on the function block button

• The “Select Function Block” menu appears as shown below. • Open “Regulatory Control Block” by clicking on the + sign. • Open the “Controller” menu and select PID. • Click OK.

OR


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-48

• Click somewhere on the Control Drawing to place the PID block. • Type in the Tagname (TIC100) • Click on the Control Drawing again to place another PID block. • Type in the Tagname (FIC100)

TIP: The cursor will have a Function Block icon on it as follows:

This means that when you click on the Control Drawing, a Function Block will appear. When you no longer wish to place a function block on the control drawing, click on the cursor button:

The Control Drawing will now have two PID controllers on it as follows:

TIP: Function Block Execution order – the order in which the function blocks are executed is the order in which the blocks are placed on the control drawing. This order is displayed in the Tag Name column on the left hand side of the drawing. The order can be changed by clicking on the number next to the tag and dragging it up or down to the place you want it to execute.

Note the dashed line. This means that the destination block (FIC100) is executed before the source block (TIC100). In the case of analog functions, this does not really matter, but the order can be changed by moving the tag in the tag column.


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-49

3. Create the Process I/O Link Blocks

• Click on the Function Block menu button.

• Select Link Block PIO • Click on the Control Drawing so that

the Link block appears. • Type in the I/O element number as

shown below. • Repeat to create three blocks.

The element names are as follows: %Z011101 (analogue input) %Z011102 (analogue input) %Z011109 (analogue output)


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-50

4. Wiring the Blocks

• To wire the blocks together, select the Wiring function from the Insert menu, or click on the Wiring button:

• To wire the first analogue input (%Z011101) to TIC100:

Click on a handle on the link block (%Z011101). You can click on any

handle, but a top one would be the most convenient. The handle will turn to a green colour.

Double-click on a handle on the TIC100 block. Again, you can select

any handle, but one on the left hand side would be most convenient. If the cursor is not directly on the handle, the connection will not be made. It may be necessary to start again. In this case, click on the cursor button and then on the wiring button again.

TIP: By clicking on the source and double-clicking on the destination, the builder automatically determines the path of the wiring. This is fine for simple drawings such as this. But there are cases when you may want to control the path of the wiring. In this case, you can click on the control drawing wherever you want to change the direction of the wiring, and then double clicking on the final destination. You can also split off from a wire by clicking on it so that a dot appears and then going from there.

5. Assigning Terminals

When wiring the blocks together, the builder assigns default terminals to the connections, usually IN and OUT. This may need to be changed. In this case, the connection from TIC100 to FIC100 should be OUT SET (rather than IN). To change a terminal assignment:

• Click on the cursor key. • Click on the terminal to be changed. • either:

click again and manually type in the terminal name or

right-click on the terminal name and select Terminal Name IO1 SET

TIP: One of the great difficulties of connecting blocks is knowing when to use terminals and when to use data items. In addition, the difference between a terminal and an item is not always clear. In the context menu, IO1 gives a list of terminals for the block, and DATA1 gives a list of the most used data items for the block. Except for CASCADE connections (as in this exercise), you should always connect terminals to data items or visa versa. You never connect data items to data items, and rarely do you connect terminals to terminals.

6. Editing the Properties of the Function Blocks

Call up the Properties of the function blocks either by double-clicking on them, or selecting Properties from the context menu, as described below: • To double-click on the Function Block, make sure that you double click

on a handle (the “X” on the border of the block) or the border of the block itself.

• To select the Properties from the context menu, click on a handle on the function block so that it goes green (that means it is selected). Then right-click on the function block and select Properties from the context menu.

For each of the function blocks, set the properties as follows:

TIP: To change the tag name of a function block, click on a handle on the block to select it, then click once on the tag name. You will then be able to edit the tag name as required.


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-53

7. Editing Function Block Details There are certain function block settings that are not set through the properties of the block. These are known as Detail Items. To access the detail items of a function block:

• select the required function block (in this case, TIC100). • either:

click on the WINDOW menu and select Edit Function Block Detail or

right click on the function block and select Edit Detail Function Block Configuration for TIC100

• In the BASIC tab, scroll down to Measurement Tracking • Set MAN mode = YES for measurement tracking

• There are no more items to be set • To save the configuration changes, select FILE UPDATE

There are other items that can be set (but will not be for this exercise).

• To access them. select VIEW Detailed Setting Items, or click on the Detailed Setting Items button:

• When finished, select FILE ‘Exit Function Block Detail Builder’.

8. Compiling and Saving the Control Drawing

• The drawing is now ready for compiling and saving.

• In the Control Drawing builder, select FILE SAVE

• In the message window, the progress of the compile will be displayed. If there are no errors, the message display will show ERROR = 0. It will then create a Status Display file for operator viewing.

If there are errors, they will be reported in the message area. The error message includes the tag name where the error occurs and what the error is.

TIP: Note that if there are errors the control drawing is not saved. If you need to exit the control drawing before you have fixed all of the errors, save it as a Working File (FILE Create Working File). When you exit, say NO when it asks if you want to save. If you have several control drawings saved as Working Files, you may not be able to compile if they use tags from each other, because these tag references are not set until the drawing is compiled and saved. To solve this situation, close the control drawing builder, and in System Builder, select FCS All Generation. This will resolve all these links and compile the drawings (provided there are no errors on them).

• Type FIC100 into the Tag Name field. • Click OK to close the dialog box.

• Save and exit the graphic builder (through

the FILE menu). TIP: The faceplates that you can see in the graphic editor are not necessarily what you

will see on the operator display. When the control group is called up on the HIS, only those faceplates that have a tag name assigned to them will be displayed. And how they look will depend on the nature of the tag. If the faceplate that you typed a tag name into does not appear, it is because you have typed in the tag name incorrectly.


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-57

9.2 Trend Configuration To set up the trend display, we must first set up the trend collection specification. Then the display group can be configured.

10. Test Function Test Function is a package that simulates the FCS and HIS functions within a PC. It runs an image of the FCS within the PC. It also runs the HIS function and creates a virtual Vnet so that the two can communicate to each other. In addition, it soft wires the inputs and outputs of the FCS so that process simulation is possible. This soft wiring can be modified to suit the application. To run test function:

• Click on the FCS you want to run. • Click on the FCS menu and select Test Function.

• A generation message appears which can be closed when finished. • A dialog box then appears where the HIS is selected. Make sure that you

select the HIS that you created the graphic in. If you select the wrong HIS you will not be able to access you control groups and graphics.


___________________________________________________________________________________ TE 33AU1C3-01 Rev 3.4 – 21 July 2005 10-60

• The Test Function Panel appears:

• The HIS function starts up and the FCS simulation function runs. • The start up is complete when the words “Completed Downloading

Wiring” appears.

• Scroll to the right and for each of the two lines set:

Delay = 3 Lag = 7 This provides a delay and lag into the system.

• Save the changes (File Save) • Download be selecting FILE DOWNLOAD • A dialog appears with a list of drawings. Make sure that the drawing you

want loaded is ticked, then click OK. TIP: The test function wires IN and OUT terminals together that already have PIO

link blocks attached to them (i.e., they are connected to process I/O). The wiring happens when the Test Function is started up. If Test Function is already running when the control drawing is loaded, you will have to create the wiring yourself. This is made easier using the Auto-wiring tool in the TOOLS menu.
