The status signals can be assigned to digital outputs. 4Congure digital outputs ^ 263
①
PID control is deacvated: a change-over is iniated from the congured PID control to speed-controlled operaon.
②
PID control is acvated again: a change-over is iniated from speed-controlled operaon back to the congured PID control.
7.3.5 Process controller diagnoscs
The following parameters serve to diagnose the process controller.
Parameter
Address Name / seng range / [default seng] Info
0x401F:001
(P121.01)
Current setpoint
(PID setpoint)
•
Read only: x.xx PID unit
Display of the current reference value (setpoint) for the process control-
ler.
0x401F:002
(P121.02)
Current process variable
(PID process var.)
•
Read only: x.xx PID unit
Display of the current controlled variable (actual value) fed back for the
process controller.

(P121.03)
Status
(PID status)
