INPUT SIGNAL PROCESSING

On a regulatory control function block the input signal is brought into the instrument (from the field or from another instrument) and then manipulated to fit the specific requirements of the loop. The common input processing functions are: Input Signal Conversion Linear: No conversion. Square root: 0.5% cutoff. Pulse input: 0-10,000Hz. Digital Filtering Auto filtering or 3 selectable filter types (.5, .75, and .875). Totalizer Time units of: Second, Minute, Hour, or Day (based upon the engineering units), 8 digits maximum. PV Overshoot Function If the input goes bad the PV displays either the last good input or the Hi or Low range limits. Calibration Manually set the PV in case of transmitter failure or calibration.

OUTPUT SIGNAL PROCESSING

The previous page shows the signal flow through the output-processing portion of regulatory control function blocks. After the signal has gone through the input processing and the control calculations (PID) then it is ready for the output processing. The control calculation is limited by the output limiter and by the velocity limiter before the signal is displayed as the MV of the instrument on the faceplate. From that point the signal goes through a signal conversion, then to the output module, and then finally to the control element. Functions in the “Output Signal Processing Block” are:

Output Limiter: Limits the function block’s output to the output module; this is displayed as the MH and ML on the tuning panel. Output Velocity Limiter: This function limits the rate of change in the output to avoid output bumps. Output Clamp: Refers to the inability to move the MV above or below the preset output limits. It displays on the instrument faceplate as CLP+ or CLP-. Preset Manipulated Variable: A preset MV (PMV) value can be specified for a function block then be activated by a sequence table based upon predefined set of conditions in the process. The loop will be forced to MAN when this function is used. The output can also be forced to 0% or 100% by a sequence table. Output Tracking: Output tracking function forces the MV of the control block to equal the value of the tracking input signal (TIN) that is coming from an external source or the value of the output’s destination (Cascade connection). Output Signal Conversion: Change the signal from analog to digital for ON/OFF control (depends upon the type of PID function block created). Analog Output: The MV signal to the analog output module generates the 4-20 mA (or 1-5 Vdc) to the control device in the field. The output has a function that makes the signal to the control device go to 106.25% on a full open and -17.19% on a full close. The output of the loop can be reversed (20-4 mA or 5-1 Vdc).

BATCH SET BLOCK (BSETU-2)

Another example of a regulatory control type instrument (Signal Setters) is the BSETU-2. This instrument is used in batch control applications such as filling reactors; the fill rate and the shutoff rate can be specified.

This instrument’s flow rate is setup by defining its scaling (shown as the “Scale high”).

• The bar on the faceplate shows the amount of product put into the vessel.

Some of the definable items on the Tuning Panel are:

• The “BSET” register shows amount of product to be put into the vessel. This also defines the scaling on the faceplate.

• The time to open (TU) or close (TD) the control valve in seconds

• The point when the closing of the control valve should start is the “PLST” register. This number is the amount subtracted from the BSET which determines the trigger point.

BSET = 2500

PLST = 200

Closing starts at “2300” (BSET-PLST) at the “TD” rate.

To start a BSETU-2

• The mode must be AUT.

• Command switch SW=1.

SIGNAL WIRING

Wiring on a Control Drawing is based upon the data type and the instrument type involved. There are several different wiring types available for connecting instruments and the process. These different types of wiring are: Process Connection: Wiring to or from an I/O connection box. This tells which I/O point will be used for the specific tag. Terminal Connection: Connection between two connection terminals. As an example; from the “OUT” of a PID instrument to “SET” of a secondary instrument in a cascade configuration. Check the FCS configuration manual for all of the allowable terminal connections. Data Referencing: A data item can be taken from one instrument and used in another function block. To do this, the required data item will be named on the output of one block and connected to the IN (as an example) of another block. Data Setting: CS 3000 has software instruments that can be used to change certain data items or gather data from within another function block. As an example of what can be changed: P, I, D, HH, HI, LO, LL, MH, and ML.

• The specific tag number and data type to be changed is defined on the detail panel.

• The actual data to load is defined on the “Tuning Panel”.

Shown below is a reference chart to showing examples of some allowable connections. This does not cover all possible combinations; please refer to the IM’s for specific detail.

DEFINING REGULATORY FUNCTION BLOCKS

Select “Function Block” under an FCS and builder “drawings” will appear under “Opened Folder”. Double-click on a drawing number to open its builder panel.

• There are 200 drawings available per FCS on CS3000.

Click on the “Function Block” icon to open the “Select Function Block” window. From here the user will select the category and sub-category to find a desired function block type.

Process Data I/O Connections Connections to the I/O modules is completed through the "Link Block" on the control drawing. The address of the module (%Zxxxxxx) or "User Defined Label" is entered into the box.

Inter/Intra FCS Process Data Process data can be brought from one function block to another by using the "AREAIN" and "AREAOUT" link blocks.

The "AREAIN" is used to bring process data from a function block in the same FCS to the "IN" (or "SET" of a cascade loop). The "AREAOUT" is used to bring process data from a function block in a different FCS to the "IN" (or "SET" of a cascade loop).

CALCULATION FUNCTIONS

Calculation function blocks are used to support regulatory control and sequence control functions, and provide general-purpose calculation functions for analog and contact signals. Calculation blocks are divided into six types depending upon the kind of calculations they perform:

1. Arithmetic Calculation Blocks: Each arithmetic calculation has a fixed number of I/O points and fixed calculation algorithm; it performs the basic arithmetic calculations for analog signals. Examples of these are:

ADD MUL DIV AVE

2. Analog Calculation Blocks: Each analog calculation block has a fixed number of I/O points and fixed calculation algorithm: it performs arithmetic calculation for analog signals. Examples of these are: SQRT Square root EXP Exponential block LAG First order lag INTEG Integration block RAMP Ramp block LD Derivative block LDLAG Lead/lag block FUNC-VAR Variable line-segment function block DLAY Dead time block TPCFL Temperature and pressure correction AVE-M Moving average block AVE-C Cumulative average block ASTM1 ASTM (Old JIS) ASTM-2 (New JIS) 3. Calculation Auxiliary 1 Blocks: These blocks have the various functions to assist the control computation. Examples of these are: SW-33 Three pole, 3-position switch. DSW-16 Selector switch for 16 constant (numerical). SW-91 One pole, 9 position switch. DSW-16C Selector switch for 16 constant (character string). DSET Data set block. DSET-PVI Data set block with PVI. 4. Batch Data Blocks: These blocks have functions to assist the setting or gathering of batch data. Examples of these are: BDSET-1L One batch data set block. BDSET-1C One batch data set block (character string). BDSET-2L Two batch data set block. BDSET-2C Two batch data set block (character string). BDA-L Batch data acquisition BDA-C Batch data acquisition (character string). 5. General Purpose Calculation Blocks: Each general-purpose calculation block has a fixed number of I/O points and but allows the user to define the calculation algorithm. Examples of these are: CALCU General Purpose calculation block CALCU-C General Purpose calculation block with string I/O

”CALCU” FUNCTION BLOCK

The “CALCU” function block allows the user to create custom calculation to meet specific process needs.

The previous page shows this calculation: 1 program 2 alias A BL222-11.SH 3 alias B BL222-11.SL 4 alias Y FC222-11.SH 5 alias Z FC222-11.SL 6 float RANGE 7 RANGE = (Y-Z) / (A-B) 8 CPV = RV * RANGE 9 end “Alias” allows a tag’s data item to be known by another name (i.e.: BL222-11.SH becomes “A”) “Float” tells RANGE it will be floating-point data. “CPV” is the calculated process variable to be output by this instrument (CL222-11). “RV” is the data coming in through the “IN” terminal block after any input processing.

ON-LINE MANUAL

For more definition of the “CALCU” block, use the “On-line Manual”.

• Create the CALCU Block and, with it selected, click on the “Edit Function Block Detail” icon.

• When the calculation window appears, select “Help”, then “Builder Definition Items”.

• Maximize the on-line manual. On the left-hand side of the on-line manual page, select “Edit Calculation Script” icon just beneath the “General-Purpose Calculations”.

• The menu at the right-hand side changes to display the different calculation data categories.

21

BATCH DATA SET BLOCK (BDSET-1L)

The batch data set block is used primarily in batch processes for adjusting parameters of control loops based upon a product recipe. The BDSET has 16 registers that are accessible from the tuning panel of the instrument. Batch Data Set blocks can be used for changing the values of:

• Setpoint (SV)

• Manipulated variable (MV)

• Alarm trip points (HH, PH, PL, LL, etc.)

• P, I, or D

• Batch settings for BSETU (BSET)

From a sequence table, the BDSET-1L can download either individual registers or all registers at once. An operator can download all registers at the same time.

REPORT PACKAGE

A report package option is provided that has pre-defined reports built in that run on Excel spreadsheets. When the report package is opened the user can select from a list of pre-defined reports that fits a specific need from “snap shots”, to shift and hourly reports, and reports that display trend data.

When a report type is selected, data will be entered in to the block fields for:

• Tag name.

• Tag data item.

• Computer name (or operator station) to get data from.

The report is then assigned a unique name and loaded into the report database.

Running a Report

The newly created report can be run from a programmable function key or by the operator station scheduler function, if data is required at a specific time.



24

REGULATORY CONTROL EXERCISE 1

This exercise will allow the user to create a cascade PID control and connect the function blocks to the appropriate I/O modules. The loops will then be tested in the “Test Mode”. You may have to refer to previous chapters for more information!

Be aware that the amount of “step by step” direction will gradually decrease as you progress through these exercises.

CREATING FUNCTION BLOCKS FOR EXERCISE 1

1. Bring up “System View” and go to project “STUDENTV”.

2. Click on “Function_Block” under FCS0101 and double click on “DR0001”, at the right hand side of the builder, to open the drawing panel.

3. Select the “Function Block” icon and then click on the ”+” in front of “Regulatory Control Block”. Next open “Controllers” from the expanded list and select “PID” from the next list that appears. Select “OK” and then click on the Control Drawing Builder page to place the PID function block.

4. Define the function block #1 as:

• Tag name: TC222A

5. With the function block selected (green), click the right mouse button and select “Properties”. Change the following items.

• Tag Comment: TEMP CONTROL

• Range: 50.0-300.0

• Engineering unit symbol: DEGF

• Lvl : 3

6. Click again on the panel to create another PID block, define the block as:

• Tag Name: FC222A

• Tag Comment: FLOW CONTROL

• Range: 0-500

• Engineering unit symbol: LB/H

• Totalizer Time Unit: “HOUR”

• Lvl: 3



25

7. Next the connection to I/O will be defined. Select the “Function Block” icon again, and then open “Link Block”. Select “PIO” from the list that appears.

8. Click on the drawing panel to place the first and define it as “%%AIN-001”.

NOTE: This is the “Label” you created for “%Z011101” in the Analog IOM definition in the previous chapter.

9. Click on the drawing panel again to place the second link block. Define it as “%%AOT-009”.

10. Place another link block on the page and define it as “%%AIN-002”.

11. Now the function blocks must be connected to the I/O’s. Click on the “Draw Wiring” icon to activate that mode.

12. Click on an “X” on the “%%AIN-001” PIO box, the “X” will turn green. Double click on any of the “X’s” on TC222A; notice the connection is automatically defined as “IN”. Where you started and where you ended defined the direction of the signal flow.

13. Connect from “%%AIN-002” to FC222A.

14. Connect from FC222A to “%%AOT-009” to define the output.

15. For the “Cascade” connection, connect from TC222A to FC222A. Notice that the “OUT” of TC222A is shown as going to the “IN” of FC222A. Move the pointer on top of the “IN” and hold the right-hand mouse button, then select “Terminal Name”, “IO1”, and “SET”.

16. Click on “FC222A”, and then click on the “Edit Function Block Detail” icon. When the new window opens, scroll down and make the “Measurement Tracking” “MAN Mode”, “Yes”.

17. Scroll down until “Fully-open, Tightly-shut” displays; change it to “No”.

• Normally the output is set at “–17.19”. In this class, this will make the loops get IOP (Input Open) alarms because the loops have the output wired directly to the inputs. An output of –17.19% would generate the IOP (when not in Test Mode) because it is below the alarm threshold.

18. Click on “File” and “Update” and then “exit”.

19. Save and, if there are no errors, exit from the control drawing builder.

Continuing the Exercise in Test Function Mode for “STUDENTV”

The test function allows the user to test FCS builder files without having an operational system. The project’s name and FCS selected define which unit will be tested.

1. At the top of the “System View” window, select “FCS” and “Test Function”. Click on “OK” on the next window to appear.

NOTE: As the test function starts the entire CENTUM VP screen now has a blue border, also an indication of being in test mode of a user-defined project.

2. Wait until the “Test Function” window displays: “Completed Downloading Wiring” before proceeding. (It takes approximately 2 minutes from when the test function is started). At the bottom of the screen select the “Generation Message” icon to open its window. Click on the “Close” box.

3. Minimize the test function window after the download completes.



26

Open the “Test Function” window at the bottom of the screen, then select “Tools”, and then “Wiring Editor”.

Now, select “File” and “Open”. When the new window appears, select the new drawing’s number and “Open”.

Use the scroll bar to find “Lag” and enter “10” for both loops. Also make sure that “Bias” is 0.

Click on “File” and “Save”. Make sure your drawing is selected on the next window to open and click on “OK”. NOTE: The “Wiring Editor” is only used for control drawings that are simulating process connections. Using the “Lag” or “Delay”, as an example, you can simulate the process response for you loops.

Displaying the Graphic Blocks

1. Under the STUDENTV Project, expand “HIS0164” and then highlight “Window”. Click on your right-hand mouse button and select “Create New” and “Window” from the menus that appear. The “Create New Window” builder window appears.

2. Select “Control (8 loop)” for the “Window Type” and change the “Window Name” to “TEMP-CTL”. Now, click on “OK”.

3. “TEMP-CTL” now appears in the list of files under “Window”, double click on it to display the graphic builder panel.

4. Click on the faceplate at the left-hand side to select it, now click your right-hand mouse button. When the new menu appears, click on “Properties”.

5. Under Winforms Control, click on Property Page. Define the tag name as “TC222A” and click “OK”.

6. Now, click on the faceplate in position 2 and define its tag name as “FC222A”, and then “OK”.

7. Save and exit from this builder.

8. Minimize the “System View” window, and then click on “NAME” in the system message area. Enter “TEMP-CTL”.

9. Click on TC222A, an arrow displays on its faceplate to show it is selected and open its “Tuning Window”.

10. When the tuning panel appears, scroll over to display “P” and “I”. Select and change P=150 and I=5. Now close this window. Make the same change to FC222A and then close its tuning panel.

11. On the window “TEMP-CTL”, put FC222A into “CAS”, and TC222A into “AUT”. Click on the box beneath TC222A and set the “SV” to 125.

12. Change TC222A’s setpoint by clicking on the SV arrow, and use the ramping arrows in the box that appears.

13. Put FC222A to “MAN” and ramp its MV up and down. What happened? ___Why?

14. Click on the “Clear All” icon in the “System Message Area”, and close the “Tool Box”.



27

REGULATORY CONTROL EXERCISE 2

The next exercise creates a level simulation where the user can define the tank level to be controlled by a level controller or a “ramp generator” that has a ramping profile configured into it.

Display “System View” again and open “DR0002” under “FCS0101” for “STUDENTV”.

• This drawing shows the loops that will be created and the connections that will be made in this exercise.
