Description
Shows value of process PID setpoint after source
selection, mathematical function limitation and
ramping.
This parameter is read-only.
Setpoint for process PID controller.
Shows process PID deviation. By default, this
value equals setpoint - feedback, but deviation
can be inverted by parameter
deviation
inversion.
This parameter is read-only.
PID deviation.
Shows status information on process PID
control.
This parameter is read-only.
Value
1 = Process PID control active.
1 = Process PID controller output frozen.
1 = Sleep boost active.
1 = PID output is being limited by par. 40.37.
1 = PID output is being limited by par. 40.36.
0 = Parameter set 1 in use. 1 = Parameter set 2 in use.
1 = Internal setpoint active (see par. 40.16...40.16)
Process PID control status word.
Activates/deactivates process PID control.
Note: Process PID control is only available in
external control; see section
(page 35).
