PID technology controller

The technology controller permits all types of simple process controls to be implemented.
You can use the technology controller for e.g. pressure controllers, level controls or flow
controls.

Principle of operation
The technology controller specifies the speed setpoint of the motor in such a way that the
process variable to be controlled corresponds to its setpoint. The technology controller is
designed as a PID controller, which makes it highly flexible.
The technology controller setpoint is entered via an analog input or via the fieldbus.
