Short Name: Alarming.HiHi.AckType
Requires: Base Development System
Class: Variable Properties
To Use: Create a property.
Gets or sets how the HI_HI 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.
|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.|
|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.
