alarms. The state of all the active alarms changes to
<ALARM_IN
-
ACTIVE>
and a new alarm log item is created.
To reset all alarms through hardware, the entity
[I/O binding alarm reset input]
must be configured accordingly. This allows you to reset all alarms on a
particular arm.
A special function key can be assigned to the “F” key on the LAD to re-
enable the device. This function
<Re-enable device>
clears all the alarms
on the device.
