6. 5 Operations supervision
6. 5. 1 Event message concept
The system generates an event message every time an event or error occurs. The
event tables in the Fault & Maintenance Manager are used to specify how often an
event message of a particular type may be generated by the system over a given
time period before the event message is sent to the allocated signal destinations.
The Fault & Maintenance Manager has 5 event tables that can be allocated to 5 sig-
nal destinations:
F = Frequency
T = Time period
