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.
