76 Ratio PID Controller

As illustrated in Figure 7-2, Ratio (PID) Controller Block Diagram, when a 3 is loaded into System Module

datapoint B00 to indicate CS3, the signal designators are as follows:

1. ANI0 = Controlled Variable

2. ANI1 = Wild Variable

3. ANO0 = Controller Output

4. CCO0 = Process Alarm

✎ Procedure

Note

To minimize sudden process changes, adjust the local setpoint

value to cause the setpoint pointer to cover the ratio tick bar before

switching to ratio control (Ratio).
