DeltaV Alarm Ranking

DeltaVAlarms are prioritized in the following manner:

Unacknowledged alarms are more important than acknowledged alarms

Alarms with equal acknowledgment status Active alarms are more

important than inactive alarms

Alarms with equal acknowledgement status and active status alarms

with higher priority (numeric) values have the greatest importance.

Alarms with equal acknowledgement status, active status and priority

valueNEWERalarms (i.e., alarms with more recent time stamps) are

more important than OLDERalarms

EveryAlarm parameteris part of aModule

EveryModule is assigned to a Plant Area

Each Workstation informs each controllerof the list ofPlant Areas in

which it is listening for alarms

Every state change detected in an alarm parameter generates an event

occurrence recordwhich is sent to Workstations which are listening for

alarms in that specific plant area

Workstations maintain a list of active alarms, ordered by importance,

from the event occurrence records they receive
