Signalling an event message to an external signal destination
Fig. 91 Flowchart of the signalling of an event message to an external signal destination
The following principles govern the way event messages are signalled to an external
signal destination:
• Individual event messages are not signalled if they occur at short intervals. The
event messages are stored temporarily for 5 minutes and then sent together to the
external signal destination.
• If over a period of one hour an attempt is made unsuccessfully to send the event
messages to the external signal destination, the signalling period is extended from 5
