Events and tripping operations
All events (with the exception of tripping operations) are provided with a time stamp and an
incoming (+) or outgoing (–) indicator, and entered in the event log.
In the event log, the last ten events registered on the CubicleBUS are stored in the COM15.
The trip log contains the last five tripping operations. Both can be evaluated via
Switch ES Power.
Events
Tripping operations
The event log has a depth of ten events and works like a FIFO memory, that is, when a new
event arrives, the last event is removed from the event log.
The trip log functions in a similar way to the event log, but only the last five tripping
operations are entered with a time stamp. An incoming or outgoing message is unnecessary
in this case.
Note
The event log and the trip log are only available with the COM15 module.
