Using Ignition , perspective 8.3.9  
Split Gateways front end and backend.

I have UDT with an alarm defined on one of its members,  
I have set the alarm ack mode to Auto , and have a script on Alarm Acknowledged Event to send the reset back to the PLC.  
However it looks like that Alarm Acknowledged Event is never triggered .  
My understanding was that when an alarm gets acknowledged , manually or automatically , the Alarm Acknowledge script should be triggered regardless.  
Is this working as designed or is this kind of a bug?  
( I even tested to just do a log print in the Alarm Acknowledged script but it never got triggered)  
( If I move the code to the end of the Alarm Active Event , the reset is sent to the PLC)

I think there's understandable confusion here, I'll bring this up as a discussion point internally. At the very least I think we could call this out in the docs.

To answer your question: if you move your script to the `Alarm Cleared` Alarm Event script, it will function as you're expecting.

Essentially, what happens internally is the alarm is being Acknowledged as a part of the Clear transition. Meaning when the alarm is no longer active and a Clear event is generated, the `auto` ack mode is automatically acknowledging that alarm and is included on the Clear event. But, as you ran into, no separate acknowledge event is generated.

thanks for the clarification .  
I can't move the script to the alarm cleared , since in our system the alarm remains latched in the plc until we send the reset back from the hmi . so I have to keep the script for resetting the plc in the Alarm Active Event.

Do you think you guys are going to add a separate Alarm Acked Event sometime in future? for Auto Ack alarms ?
