Determines the direction of action, i.e. how the reference variable is assigned to the controlled variable.
Mode of operation of the positioner
Positioning value
This positioning value is calculated by the Function Block from the SETPOINT for the Transducer Block in [mm],
[degrees] or [%]

Travel range or rotational angle range
Top and bottom values of the actual working range in [mm] or [degrees]. A non-linear characteristic is adapted
to the reduced travel.
Maximum value for the top value = Rated travel
