Auto Acknowledgment of Specific Alarms
There is Customer Requirements that , The Alarms of the Some tags has to be disappeared from Alarm List as soon as the alarm condition become normal without Operator Acknowledgment.
Is there any way to implement this? The System is ABB 800xA Version 5.1 Rev B with Advant Connect.

I assume 800xA for Advant Master?
Have you tested with a custom event treat setting (using the AUDIBLE, AL_TOBLK, AL_FRBLK and PERSISTB flags)? Not all permutations are allowed (AS500 OS supported more permutations than 800xA since it did not have to be OPC AE compliant).
Acknowledgement of an alarm in an alarm list of 800xA is an operator driven function; to have an alarm to transit from "ACT, UNACK" to "RTN" it needs to be acknowledged somehow. Writing FALSE to Alarm Global Properties:IsAlarmUnack will perform acknowledgement. Maybe you can create some PG2 PropertyWriter doing that; but the element needs to be on display for this to work.
