Property of Variable.

Gets or sets how the CUSTOM alarm for a shared variable is acknowledged. To use this property, you must install the LabVIEW Datalogging and Supervisory Control Module. A value of 0 indicates that LabVIEW acknowledges the alarm when the shared variable value returns to a normal state. A value of 1 indicates that LabVIEW does not acknowledge the alarm until the user acknowledges the alarm, regardless of the alarm state. A value of 2 indicates that LabVIEW never acknowledges the alarm.

Note  You can enable alarming only for network-published shared variables.

This property is similar to the Ack Mode option on the Configure Alarms dialog box.
