Micromod Micro-DCI: 53MC5000 Multi-Loop Process Controller CUSTOMIZATION GUIDE - Manual (Page 53)

3.0 F-CIM (CONTROL INTERCONNECTION MODULES)
Control Interconnection Modules provide a method of customizing the 53MC5000 (Extended Func-
tionality) controller that is more flexible than the FIX 1 Flexible Control Strategy but not as flexible as
F-TRAN programming.
F-CIM loop generation is a building block method for implementing control configurations. F-CIM
programing does not require knowledge of computer languages or programming experience. Control
Strategies are implemented by choosing prewritten modules from the module library and intercon-
necting them to perform the desired function.
When the Function Index B00 is set to 99 a sequence of up to 100 modules is continuously executed
at the rate specified by SCAN B03.
Each F-CIM is defined in the Module Library in this chapter. The modules include:
• General Modules:
read
write
display
• Numerical Operations:
pre-written selectable equations
add, subtract, multiply, divide
square root
log (base2)
X to the power Y
absolute value
• Logical Operations:
AND
OR
EXCLUSIVE OR
• Control Modules:
setpoint generator
process variable deviation
PID algorithm
auto/manual switching
There is a page in this chapter for each F-CIM; these pages list the inputs and outputs available, as
well as allowable associated database parameters. A function block diagram is also shown.
To use F-CIM programming:
1. Define the process control function to be implemented.
2. Become familiar with the capabilities of the function blocks in the Module Library in this
chapter.
3. Draw a function block diagram using these function blocks.
4. Enter data on a work sheet. (Blank worksheets are provided in the back of the manual.)
5. Enter the function block input values and parameters into the database.
A sample F-CIM program is shown in Section 3.4.
