(*1) Priority:
0 = the associated alert will never occur.
1 = the associated alert is not sent as a notification. If the priority is above 1, then the alert must be reported.
2 = Block alarm and update event have a fixed priority of 2.
3-7 = advisory alarms (PV.STATUS = Active Advisory Alarm)
8-15 = critical alarms (PV.STATUS = Active Critical Alarm)
