3.2.48 Process controller (PCTRL1)
Purpose
The FB is used, for instance, as a higher−level controller (dancer position controller, tension controller,
pressure controller etc.).
The control characteristic follows the ideal PID algorithm, but it can also be changed over to a PI or
P characteristic.

Function
Setpoint and actual value are sent to the process controller via the corresponding inputs and
processed according to the selected control algorithm (control chararacteristic).
