need to connect an additional analogue amplifier block
between the analogue output of the special function and
the real analogue output. Using this amplifier, you
standardize the output range of the special function to a
value range of 0 to 1000.
PI Controller
Description of function
It is for proportional-action and integral-action controllers.
You can use both types of controller individually or
combined.
Connection
Description
Input A/M
Set the mode of the controller:
1: automatic mode
0: manual mode
Input R ( )
Use the input R to reset the output
AQ. As long as this input is set, the
input A/M is disabled. The output
AQ is set to 0.
Input PV
Analogue value: process value,
