Hiding
Hiding is a way of avoiding alarm situations where numerous sequential alarms
make it hard to determine the root cause of a problem. By using the hiding function
in 800xA, it is possible to hide non-relevant equal alarms. The hiding of alarms is
initiated by hiding rules, which can be process conditions or logical expressions.
All the hiding rules are kept in the Hiding Mask Manager.
Hiding affects the presentation of the alarm list. If an alarm is irrelevant it should
not be shown in an alarm list. An alarm is irrelevant if it does not require an action
from the operator. The Hiding alarm function will help the operator to get the alarm
lists clearer from irrelevant alarms.
