Acknowledging Alarms with Signature Required

You can use the SignedAlarmAck( ) script function in Industrial Graphics to require a signature to acknowledge alarms. Add the script function to a symbol as described in the Creating and Managing Industrial Graphics User Guide, and then embed the symbol in the WindowMaker window.

When you acknowledge the alarms at run time, 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 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 ArchestrA alarms.

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