Settings; Setting The Setpoint - gefran GFX4 Configuration And Programming Manual

The controller has the following setpoint controls.

SETTING THE SETPOINT

The active (control) setpoint (SPA) can be set by means of the local setpoint (_SP) or the remote setpoint (SP.rS). A
remote setpoint can assume the value of an auxiliary input or one set via serial line (SP.r).
The remote setpoint can be defined in absolute value or relative to the local setpoint; in the latter case, the control
setpoint will be given by the algebraic sum of the set local and the remote setpoint.
