ISEL Function Block
February 2017
Alarms are grouped into five levels of priority, as shown in table E‐11.
Table E‐11. ISEL Function Block Alarm Priorities
Priority Number
0 The priority of an alarm condition changes to 0 after the condition that caused the alarm is corrected.
An alarm condition with a priority of 1 can be recognized by the system. The device monitors the alarm but does not report it
1
until requested by the host system.
An alarm condition with a priority of 2 is reported to the operator, but generally does not require operator attention (such as
2
diagnostics and system alerts).
3-7 Alarm conditions of priority 3 to 7 are advisory alarms of increasing priority.
8-15 Alarm conditions of priority 8 to 15 are critical alarms of increasing priority.
1. The priority classes "advise" and "critical" have no relationship to Plant Web Alerts.
