9.1 Foreword F-CIM (Control Interconnection Modules) provides a method of optimizing the controller’s standard functionality. This method is more flexible than the FCS, but not as extensive and flexible as the F-TRAN. But F-CIM is easier to program than F-TRAN. As we explained before, F-CIM programming is done by building the strategy using building-blocks from the Module library. The Module library is a collection of predefined function blocks.

It is more powerful than the FCS method because each strategy can consist of up to 100 blocks, the order of execution can be specified by the user, and many of the blocks are reusable.

It is also possible for the user to make custom function blocks and add them to the Module Library.

Creating a custom F-CIM module is not in the scope of this training coarse and will not be covered.

9.2 Objectives In this lab we will introduce F-CIM programming and implement a simple control strategy using F-CIM. After completing this lab, you should know how to

• Create a F-CIM control strategy using F-CIM function modules described in the Customization Guide

• Enter an F-CIM control strategy using the faceplate keys

• Create an F-CIM control strategy using the MicroTools Graphical Editor

• Download an F-CIM control strategy using MicroTools

9.3.2 Methods of programming F-CIM There are two methods for configuring F-CIM. They are:

1. From the controller’s front panel

2. From Micro-Tools - The F-CIM Control Strategy can be configured using the Micro-Tools F-CIM graphical editor. F-CIM function blocks are graphically placed on a worksheet and the connections between them are drawn as connecting lines. The resulting control strategy can be downloaded to the controller via a communication port.

Using Micro-Tools to configure F-CIM is easier and more convenient than configuring from the front of the instrument. We will cover both the methods in this lab.

9.3.3 Steps of Programming F-CIM The steps involved in programming the controller using F-CIM are:

1. Define the control strategy to be implemented

2. Select the function blocks that can be used for implementing the defined control strategy

3. Draw the function block diagram using these function blocks

4. Enter data on a work sheet for the function blocks

Each function block has its associated inputs and outputs. In general there are 4 inputs to each block. These inputs are labeled as follows:

• A, B and C – these inputs are configurable

• Sn-1 – this input is the output of the previous step (previous function block)

The F-CIM program is executed in steps. The 53MC5000 controller can execute 100 F-CIM program steps. Step number range from 0 to 99. In general, each Function Block requires one step.


9 - 4

9.4 Instructions 9.4.1 Part 1 – F-CIM Programming from front face

1. Define the process control strategy to be implemented first: The strategy involves a single loop PID control. We will add the following in addition to the PID control:

• Enable Output tracking based on closure of Contact Input 1. We will assume that the output tracking signal comes from Analog Input 2

• Enable Setpoint tracking of Process Variable when the controller is not in Auto mode. We will assume that the PV comes from Analog input 0

• Disable Remote setpoint on closure of Contact input 0. We will assume that the remote setpoint input comes from Analog Input 1.

2. Select the F-CIM modules: We will use the following F-CIM modules

1. READ – for reading ANI-1 for remote setpoint

2. SP0 – Setpoint generator for Loop0

3. DEV0 – Deviation Calculation for Loop0

4. PID0 – PID for loop0

5. A/M0 – Auto Manual selection for Loop0

6. WRITE – for writing the output of A/M0 to Analog Output 0

7. DISPLAY – for displaying the loop parameters

3. Draw the function block diagram using these function blocks: The function block diagram is shown in the next figure. This diagram can be drawn on paper. This diagram will help you understand what exactly needs to be programmed.

PROGRAM REFERENCED I/O

There is an F_CIM number associated with each function block. The blocks are referenced using their F-CIM number. Certain blocks can be reused in the program. These blocks are of type R. Examples of reusable blocks: Math, Logic, Read, Write etc. Certain blocks can be used only once in the program. These blocks are of type N. Examples of blocks that can be used only once: PID0, PID1, SP1 etc. Table 9-2 gives a complete listing of the blocks, their inputs and type.

5. So far it has been only paperwork. The next step is to enter the function block inputs and parameters into the database of the controller.

Enter PROGRAM mode: Press the Dot button to enter the engineering mode. This may require you to press the Dot button more than once. The engineering mode will display a line of text at the bottom of the screen. The line of text will contain the word DISPLAY, CONFIGURE or PROGRAM. Press the F2 button until PROGRAM is displayed at the bottom as shown in the next figure:

Figure 9.2. Program Mode

• Now press F3 to enter the program mode.

• 53MC5000 controllers can be configured for password protection. The controllers you are using should not have any password requirements. When you are working on controller in normal plant operations, passwords may be required. If you are prompted for a password, the password must be entered before you may continue.

• The display will show either VIEW, BUILD, or ERASE at the bottom of the screen as shown in the next screen.

You can perform three options in the F-CIM Program mode:

1. View – This mode is for viewing the step results of an F-CIM program

2. Erase – This mode is for erasing an existing F-CIM program

3. Build – This mode is for creating a new F-CIM program or modifying an existing F-CIM program.

number is next, followed by the three possible inputs: A, B, or C. The bottom line displays REPLACE.


• In the BUILD mode, the user may elect to REPLACE the contents of the step,

INSERT a new step or DELETE the existing step. Pressing the F2 button rotates the selection between these three options.

• We will begin modifying Step 0 to match the needs of our demo program. When REPLACE is displayed at the bottom of the screen, press the F3 button. This will begin the data entry phase as shown in the next figure:

• An arrow will appear on the right side of the display screen which points at the function code entry as shown in the next figure. The default value is 042. This value will appear at the bottom of the display and allow you to modify the value.

Training Manual

F-CIM Lab

9 - 15


• In our program, this value should read 086. Refer to Table 9-3. Use the

UP/DOWN/LEFT/RIGHT keys to modify the data to read 086. When the value is correct, press the F2 key (not F3) to write the new value back to the step. When the F2 key is pressed, the Function code entered (086) will be displayed in the FUNCTION position and the pointer will move to the next data position, in this case the Input A. See the next figure:



9 - 16

• Next we want to enter a value of H01 for the A Input of this F-CIM block. (Refer to Table 9-3, Step 00). When the default entry for A is shown at the bottom (*****), use the UP/DOWN/LEFT/RIGHT arrow keys to enter the value H01 at the bottom and then press the F2 button to accept. Now H01 will be displayed below A on the display and the pointer will jump to the B input as shown in the next figure:


• The default value of B is shown at the bottom now. As per our work sheet (Table

9-3), we do not connect anything for the B and C inputs. Press F3 to save this step. Now you will notice that REPLACE displayed at the bottom as shown in the next figure. Programming of Step 00 is complete now. So we should now proceed to the next step (Step 01).

• Press F1 again. You will be at the top level (PROGRAM/DISPLAY/CONFIGURE) now and the display will look like the next figure:


9 - 22

Figure 9.20. PROGRAM

11. Enter the CONFIGURE mode: An important step in F-CIM programming is that after completing the code entry into the controller, you should tell the controller to run the F-CIM program. This can be achieved by changing the Function Index (Data point B000) of the database to a value of 99.

• If PROGRAM is displayed at the bottom, press F2 until CONFIGURE is displayed at he bottom.

• If nothing is displayed at the bottom, press the EMODE button (Dot button /F4 button) and then the F2 button to display CONFIGURE at he bottom.

Figure 9.21. CONFIGURE

12. Run the F-CIM program: Press the F3 button while CONFIGURE is displayed at the bottom. The display will show POINT L at the bottom.

• Press F3 to accept the configuration mode. On design level A controllers, the bottom line should now display the following: POINT L . On a design level B controller, the bottom line should read DATAPOINT or MODULE . Press the F2 button until DATAPOINT 5 is displayed.

• Press F3 to accept the DATAPOINT configuration mode. The bottom line should now display the following: POINT L

• Use the UP/DOWN/RIGHT/LEFT arrow keys to enter B00 at the bottom and then press the F3 key to select it.

• Enter a value of 99 and then press the F3 key. Now the controller should start running the F-CIM program you did and the display should look like the next figure:


9 - 24

Figure 9.22. FCIM RUNNING

13. Test the program: It is time to test your program now. Review the requirements as in step 1.

• Make sure that the control mode is AUTO. The letter A should be displayed just above the Output bargraph (horizontal) at the bottom as shown in the figure above.

• Note the value of the setpoint. It should be same as the value of the output because we configured the output to track the setpoint in Auto mode.

• Press the A/M button to put the control loop in Manual Mode. The letter M will be displayed just above the Output bargraph (horizontal) at the bottom.

• Increase or decrease the value of the output using the LEFT/RIGHT keys. It should be different from the setpoint value.

• Put the control mode back in AUTO mode by pressing the A/M button. Watch the output value changing automatically to match the setpoint value.

You an also test the program by closing the contact input 1. This should enable Output tracking. The tracking signal will be read from the Analog Input 2. The other requirements were:

• Enable Setpoint tracking of Process Variable when the controller is not in Auto mode. We will assume that the PV comes from Analog input 0

• Disable Remote setpoint on closure of Contact input 0. We will assume that the remote setpoint input comes from Analog Input 1.

9.4.2 Part 2 - F-CIM Programming from Micro-Tools In Part 1, we learnt how to program F-CIM from the front keypad. In this Part, we will learn how to program F-CIM from Micro-Tools. We will use the same control strategy and the same worksheet (Table 9-3) for doing this F-CIM program using Micro-Tools.

1. Create a new F-CIM program:

• Select the Project Manager in Micro-Tools. From the Project Manager, select the Project folder and then the controller that we will create the FCIM strategy for.

• When the controller tag name is highlighted, the right side window will list the functions that can be performed for this controller (refer to figure below).

Figure 9.23. Project Explorer

• The third item in the list is the FCIM. Right mouse click on the editor and select

edit from the pull-down menu.

• Two new windows will appear on the screen, one large window work area and second smaller window containing a function block selection list. See the next figure


9 - 26

Figure 9.24. FCIM Editor

In the Function block selection list, the modules are organized by their function. As an example all the inputs are grouped together. If you left mouse click on the Input grouping the list will include ANI and CCI. No attempt is made to distinguish ANI 0 from ANI1 or ANI2, etc. The module number is assigned after the module is dropped.

2. Place an ANI module on the editor screen:

• Select the ANI module by left mouse clicking on ANI. Once selected, you do not have to hold down on the mouse. As you move the cursor away from the selection list you will see a change in the cursor indicating a module is being moved around.

• Find a spot on the drawing area and left mouse click to drop the module. You will notice that a module has been placed on the drawing and that the ANI is ready to drop another copy of the ANI. See the next figure. To deselect the ANI module selection, right mouse click.

Figure 9.25. FCIM BUILD 2

If the size of your work area is not large enough, you can zoom out to view more area in your work area. The zoom command can be selected from the tool bar at the top of the window. The zoom out will appear as a magnifying lens with a “-“ sign in the center. The zoom in is a magnifying glass with a “+” in the center. If you need to reposition the

module on the worksheet, left mouse click on the module. The module will be outlined in red when selected. If you left mouse click on the module and hold the button down you can drag the module to its new position.

3. Configure the Analog Input 0:

• Double-click on the block to popup the module parameterization screen as shown in the next figure. This will allow you to modify the parameters associated with the module.

• Change the module to make sure that the configuration reference is the proper module ID. To do this, click on the UP/DOWN arrows next to the Channel field on the Analog Input Parameter Configuration menu and change the value to 0.

All modules selected from the function block list are always module zero.

Figure 9.26. ANI Parameter Configuration

• Click on the OK button to save the configuration of ANI0

4. Add the other blocks: Let us continue by creating our single loop control strategy by adding the remaining necessary modules to the editor. We will require the following Control modules:

• Deviation Subroutine module (DEV)

• Setpoint Subroutine Module (SPG)

• PID Subroutine module (PID)

• Auto/Manual Switch Subroutine module.

• Analog output module

• Display module - The display module is used to control the pushbuttons for screen manipulation

• Drag and drop each of these modules onto the worksheet. Your editor (work sheet) will look like the next figure: The position of modules is not important.


9 - 28

Figure 9.27. Blocks in the F-CIM Editor

5. Connect the blocks: Our next step is to link the modules together to form a working control application.

You will notice that the modules have inputs on the left side of the module and outputs on the right side. Inputs are further identified as empty or hollow squares, circles or diamonds, Outputs are filled squares, circles or diamonds. The circles and squares also have meaning. Circles represent analog or floating point type signals while squares represent discrete or logical type signals.

What remains to do is link the modules together to form the final control strategy. Linking the modules requires drawing a line from the output of one module to the input on the next module. The squares, circles and diamonds are an aid in keeping these connections correct, discrete connects to discrete, analog connects to analog.

• From the tool bar, select the Signal wire tool. This is the tool that looks like a black diagonal line with a black dot at each end.

• Select this tool with a left click. The tool is selected when the tool is outlined in red. Begin by connecting the output of ANI0 module with the PV of the DEV module.

• Use the mouse to left click on the output circle of the module. Drag the mouse to the PV input circle on the DEV module and let click the mouse again.

• Micro-Tools will draw the connecting line.

6. Connect the remaining lines:

1. ANI1 module output to RSP input of the SPG module

2. SPG Module SP output to SP input on the DEV module

3. DEV module DV output to the DV input on the PID module

4. PID module CO output to the CO input on the AMS module

5. AMS module OUT output to the ANO module input.

6. AMS module OUT output to the RF input on the PID module

7. AMS module AUT output to the CTC input on the PID module

At this point we have completed a simple strategy but there is a few more step to being complete. When the drawing is complete, close the window.

7. Save the strategy: You will be prompted several times to save the new strategy.

Figure 9.29. F-CIM Save

• Saving changes will overwrite any previous versions. You will next be asked if

you would like to view the step list. Answering Yes will give you the opportunity to view the step list that you would have had to compile by hand before manual entry.
