Fields
Derivative Source Determines whether a change in process variable or a change in
error (setpoint- process variable) causes derivative action.
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
current process variable. In that case the process is not upset by
the change from manual to local.
Freeze on Bad Value If selected and if the process variable read from the auxiliary input
channel is not a valid reading, the controller output is not changed.
Alarm Status
The alarm status indicates when the process variable is outside of the
user specified range
of upper alarm limit and lower alarm limit .
The alarm can be specified as an absolute range or as a deviation from
setpoint.
