n PID Feedback Input Methods
Input one feedback signal for normal PID control or input two feedback signals can for controlling a differential process value.
Normal PID Feedback
Input the PID feedback signal from one of the sources listed in
PID Feedback Source
Analog Input A1
Analog Input A2
Analog Input A3
Pulse Input RP
Note: A duplicate allocation of the PID feedback input will cause an oPE07 (Multi-Function Analog Input Selection Error) alarm.
Differential Feedback
The second PID feedback signal for differential feedback can come from the sources listed in
feedback function is automatically enabled when a differential feedback input is assigned.
PID Differential Feedback Source
Analog Input A1
Analog Input A2
Analog Input A3
Note: A duplicate allocation of the PID differential feedback input will cause an oPE07 (Multi-Function Analog Input Selection Error) alarm.
