Single Loop Process Controller Instruction Manual
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).
