5.1. functions

Type 8692 - Position controller
The position of the actuator (stroke) is regulated according to the
position set-point value. The position set-point value can be spec-
ified by an external unit signal (or via field bus).
Type 8693 - Process controller
The process controller is integrated into a control loop. The stroke
of the valve is calculated from the process set-point value and the
process actual value via the control parameters (PID controller). The
process set-point value can be set by an external signal.
