When Show Active Alarms is selected from the State Filter
drop-down list, inactive alarms (State = '0") will be hidden
on the list, and only active alarms (State = "1") will appear.
For example: High Pressure switch alarm records before
filter is applied.
High Pressure switch alarm records after filter is applied.
Status Filter applies to Alarm Status.
When Show Alarm Event is selected from the Status Filter
drop-down list, any non-alarm events pertaining to user
action (acknowledgement and reset) is filtered off the list.
Only alarm-related events appear.
For example: High Pressure switch alarm records before
filter is applied.
High Pressure switch alarm records after filter is applied.
Any alarm events pertaining to user action
(acknowledgement and reset)is filtered off the list.
Combining both State Filter and Status Filter can
enhance alarms viewing even more.
For instance, one needs to view only events when alarms
occurred and hide all other ones (aka one alarm event for
each alarm).
