5.8.3 Priority concept
Possible priorities for alarms and messages are --, 0, 1, 2 to 99. This priority range is divided into 10 alarm
groups (decades 0..9):
Priorities Function
-- No message is generated, no alarm is signalled
0, 10, 20,...90 Lowest priority, message entry only in the message list, no alarm is signalled
1, 11, 21,...91 High priority alarm - entry in alarm and message lists, remote alarm is signalled, local
alarm is signalled (horn),
triggering of the alarm relay PRIO1, e.g. in the event of potential stock loss
2, 12, 22,...92 High priority alarm - entry in alarm and message lists, remote alarm is signalled, local
alarm is signalled (horn),
triggering of the alarm relay PRIO2, e.g. for faults that Customer Service can rectify on
the next day
3, 13, 23,...93
4,14,34,…94
5,15,25,…95
6,16,26,…96
7,17,27,…97
8, 18, 28,...98
Low priority entry in alarm and message lists, remote alarm is signalled, local alarm is
signalled (horn),
triggering of the multi-function relay AUX (ONLY for one decade, e.g. X3)
9, 19, 29,...99 Low priority entry in alarm and message lists, local alarm is signalled (horn),
triggering of the multi-function relay AUX (ONLY for one decade, e.g. X3)
This division into alarm groups (decades) facilitates maintenance group oriented alarm management. For more
information, see chapter Extended alarm destinations 4..15, page 24 Extended alarm destinations 4..15.
