7.7.2
Cyclical monitoring
Options:
Deactivated
Activated
The cyclical monitoring is used to monitor specific, selected group objects for the correct function
of the device. For each group object monitored it is possible to define a monitoring time during
which the group object monitored must be received.
If the group object is received in the defined time, the monitoring time starts again immediately af-
ter the reception of the group object. If the group object is not received in this time, it can be speci-
fied how the device is to behave.
•
Deactivated
: The cyclical monitoring is deactivated.
•
Activated
: The cyclical monitoring is activated. The dependent parameters for monitoring the in-
dividual group objects are displayed. For each group object it is possible to decide separately
whether it is to be monitored or not.
Note
For all cyclically monitored group objects it is important to set the behavior of the sending device
correctly. The group objects must be sent cyclically and the cycle time must be less (= more fre-
quent) than the receive time monitored.
Recommendation: Monitoring time = 2 × sending cycle time
Do not select times that are too low because this configuration can cause a high bus load and the
probability of an error increases.
