Property Description
You can select one of four parameters to change the alarm status
entered in the log:
• MANUAL_CLEAR : Alarm will be acknowledged and removed
from the active list.
• MANUAL_ACK: Alarm will be acknowledged, but not removed
from the active list.
• NACK: Alarm will not be acknowledged or removed from the
active list. However, the comment entered for the
property will be entered into the log.
• AUTO_ACK: If the status of an alarm reads AUTO_ACK, it
indicates that the alarm was automatically acknowledged by the
Alarm Notifier when it occurred. You can cause an Alarm Notifier to
automatically acknowledge all alarms for a data point by setting
Byte 5 of the property for the data point to 1
when you create your Alarm Notifier with AlarmNotifierSet. You
can still enter comments for the log file using this function if an
alarm was automatically acknowledged. For more information on
the property, see Input Data Points on page 8-
10.
The following example acknowledges an alarm caused by the NVL_AlarmGenIn1 data point.
