Remote Setpoint (RSP)
The DPRSOO can be configured to receive an externally generated
signal and use it as a remote setpoint (RSP). The controller receives
the RSP value via analog input Al2 and uses this, or the extra internal
setpoint, as the setpoint value when the user pressed the R button.
The user may condition the incoming remote signal using the
following functions:

An arithmetic expression (or calculation), can be selected using
FCODE 108. The result is used as the RSP input. The values of
Ration and Bias are determined by FCODE 1 and 2.
