Acknowledge Alarm (Single)

Last Modified: July 9, 2021

Acknowledges an active alarm instance on the server.

An alarm instance remains active until you acknowledge and clear it. Typically, the application that sets the alarm clears it when the condition(s) that triggered the alarm no longer exist. An operator must acknowledge the alarm in the user interface or call this VI.

Use Query Alarms to find alarm instances you want to acknowledge.


SystemLink Cloud does not support this VI.
