Gets or sets how the LO alarm for a shared variable is acknowledged. To use this property, you must install the LabVIEW Datalogging and Supervisory Control Module.

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

This property is similar to the Ack Type option on the Alarming page of the Shared Variable Properties dialog box.

Values
0 Auto (default)—indicates that LabVIEW acknowledges the alarm when the shared variable value returns to a normal state.
1 User—indicates that LabVIEW does not acknowledge the alarm until you acknowledge the alarm, regardless of the alarm state.
2 None—is obsolete.
3 Each Occurrence—indicates that LabVIEW does not acknowledge the alarm until you acknowledge the alarm. LabVIEW generates a new alarm instance whenever the alarm changes from a normal state to an abnormal state.

If you specify Each Occurrence for this property, LabVIEW may generate a large number of alarm instances before you acknowledge them.
