Acknowledge Alarm (Single) (G Dataflow)
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 node.
Use Query Alarms to find alarm instances you want to acknowledge.

alarm in
Active alarm instance you need to acknowledge.
note
Information you want to include about the alarm acknowledgement.
clear alarm
A Boolean that determines whether to clear an alarm without waiting for the application that set the alarm to do it.
Default: False
error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
alarm out
Active alarm instance you acknowledged.
acknowledged?
An array of Booleans that determine whether your team acknowledged the alarm instances.
error out
Error information.
The node produces this output according to standard error behavior.
