PID controller deviation message OD
The digital output configured as OD is activated when a user defi-
nable PID deviation (actual value versus setpoint value) is
exceeded. The OD output remains active as long as this differential
is exceeded.
X If you want to configure a programmable output as OD, you
must set the threshold under PNU C44 at which the OD signal
should be activated.
X Then, program one or more of the digital outputs 11 or 12 as
the OD output, by setting the value 04 under PNU C21 or C22 .

– 0 to 100% If the deviation between the setpoint and actual value exceeds the
value entered here when the PID controller is active, the OD signal
activates.
