Alarm Properties for Status Points
You can define the following types of alarms for a status point:
• State alarms
• Alarms on transition
• Control failure alarms
• External change alarms
State Alarms for Status Points
Any of the PV states of a status point can be defined to be an alarm state. For
example, you might define an alarm for the FAILED state of a valve so that the
operator can be alerted as soon as there is a problem.
As well as defining which state(s) should generate an alarm, you can also define
the priority of each alarm.
To associate a PV state with an alarm:
1 Select the Enable checkbox for each PV state that is to be used in
generating an alarm.
2 For each state that is to generate an alarm, select an alarm priority from the
Priority selection list, and specify an alarm sub-priority in the Sub-Priority
field.
Alarm priorities and sub-priorities are described in “Defining Events, Alarms,
and Alarm Priorities” on page 162.
