Activate monitoring control values
Options: No
Yes
This parameter sets the monitoring for the control value input(s). Any remaining telegrams on the
communication object(s) are detected.

No : Control value monitoring is deactivated.

Yes : Control value monitoring is activated.
Dependent parameters:
Monitoring time
in s [30…65,535]
Options: 30...120...65,535
This parameter sets the maximum time allowed between two control value telegrams. An error is
reported if this time is exceeded.
Note
The monitoring time should be at least twice as long as the cyclical transmission time of the
control value, so that the absence of a signal, e.g. due to a high bus load, does not immediately
trigger an error.
Where there are two control value inputs, the following additional parameter appears:
Function of monitoring
Options: Monitoring current control values
Monitoring active and inactive
control values
This parameter determines the scope of monitoring.

Monitoring current control values : Only the currently selected control value input is monitored
for incoming telegram continuity. After a switchover (via Communication object "Toggle control
value A/B" or Largest value ), monitoring restarts.

Monitoring active and inactive control values : Both control value inputs are always monitored
independently of each other. An error is reported if an object's time is exceeded.
Note
The fault is reset if both control values are received within the monitoring time.
