Hi, 

    I am using Simatic WinCC V7.5 SP1 with SCC V9.08 and facing an issue with acknowledging alarms from the Alarm List. The behavior is inconsistent. Attached video for your reference.

If you have any solution to solve above problem then please let me know.

Thanks,

Hello Bye Murof,

   Thanks for your reply.

single acknowledgement button also not working.

I inserted new Alarm control and tried to acknowledge from that new Alarm control list but its not working. Attached video for your reference.

Does it have worked in the past? - When I start the SCC runtime, I am able to acknowledge a few alarms, but after some time it stops working. The behavior is inconsistent.

Thanks,
