Acknowledge alarms when signature is required

You can use the SignedAlarmAck( ) script function in Industrial Graphics to require a signature to acknowledge alarms. See "Signature Security for Acknowledging Alarms" in Creating and Managing Industrial Graphics User Guide for information about adding the script function to a graphic. Then, embed the graphic in the WindowMaker window or an AVEVA OMI layout.

When you acknowledge the alarms at runtime, the script function checks for a required signature. If a signature is required, it checks Galaxy security settings and alarm priority. If any alarm in the list falls within the configured conditions, you must provide your signature to acknowledge the alarms. You must sign in to acknowledge the alarms if no user is logged on to the InTouch or OMI application.

If any alarm in the list is requires a signature, then a signature is required for the entire list of alarms.

Note: The SignedAlarmAck( ) script function supports only System Platform alarms.

By inspecting the Alarm Viewer or the Alarm Control client, you can determine if the alarm acknowledgements were successful.
