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

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
