7.6.55 Process controller (PCTRL1)
Purpose
TheFBis used,for instance,as ahigher-levelcontroller(dancerposition controller, tensioncontroller,
pressure controller etc.).
The control characteristic is according to 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).
