AUMA ACV 01.2 User Manual

The process controller [2] receives the process setpoint E7 and the actual process
value E4 (e.g. from a sensor). On the basis of both values, the process controller
calculates the position setpoint E1 for positioner [3]. In turn, the positioner [3]
compares this target setpoint with the actual position value E2 of the valve and issues
the operation commands (OPEN - CLOSE) for the actuator.
