Wiring a PID controller
You integrate a PID controller in your circuit as a contact and
coil.

Parameter display and parameter set for PID controller:
J
Three separate manipulated variables can be output. One
manipulated variable can be output via an analog output.
Two manipulated variables can be processed via two pulse-
width modulated outputs. It is therefore useful to run up to
three closed-loop controllers per program simultaneously.
Projects can be structured by selecting the controller
number.
Example: Project with 3 devices
Program 1: Controller DC 10, 11
Program 2: Controller DC20, 21 and 22
Program 3: Controller DC30
