Active
Read-only. Shows the status of the alarm as ‘Yes’ if it is active, or No, if inactive. The
active/inactive state depends on the Latch type (above) and acknowledgment status of the
alarm. Always shows ‘No’ if the alarm is inhibited (below).
Inactive
As for ‘Active’ above, but shows ‘Yes’ if the alarm in inactive and ‘No’ if the alarm is active.
Always shows ‘Yes’ if the alarm is inhibited (below).
N.acknowledged
As for ‘Active’ above but shows ‘Yes’ for as long as the alarm is unacknowledged, and ‘No’
as soon as it is acknowledged. Always shows ‘No’ if the alarm is inhibited (below).
Acknowledgement
Fleetingly goes ‘Yes’ on alarm acknowledgement, and then returns to ‘No’.
Inhibit
When ‘Inhibit’ is enabled, (tick symbol), the alarm is inhibited. Status is set to ‘Off’; ‘Active’
and ‘N.acknowledged’ are set to ‘No’, and ‘Inactive’ is set to ‘Yes’. If the alarm is active
when inhibit is enabled, then it becomes inactive until inhibit is disabled, when its status
depends on its configuration. Similarly if the alarm trigger becomes active when the alarm
is inhibited, the alarm remains ‘off’ until inhibit is disabled, when its status depends on its
configuration.
