PID controller
The display system provides 32 PID controllers DC01 to
DC32. The PID controllers allow you to implement closed-
loop control functions.
Wiring of a PID controller
You integrate a PID controller in your circuit as a contact and
coil.
Figure: 110: Display system circuit diagram with PID controller
Caution!
A knowledge of closed-loop control is required in order to
use the PID controllers.
The control system must be familiar so that the PID
controller can function correctly.
h
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. Three separate manipulated variables can
be output.
Example: Project with 3 devices
Program 1: Controller DC 10, 11
Program 2: Controller DC20, 21 and 22
Program 3: Controller DC30
