Setpoint Tracking If setpoint tracking is selected, when the controller is changed from
the manual mode to local mode, the setpoint is set to equal the cur-
rent process variable. In that case, the process will not be upset by
the change from manual to local mode (operating mode).
Derivative Source Determines whether the derivation action is done on a change in
process variable or a change in error (setpoint - process variable).
Alarm Type Determines whether the alarms are absolute or deviation.
Controller Action Determines whether the controller is direct or reverse acting.
