Audible Alarm Not Silencing
We are running AC450 controllers with a 800xA 5.1 FP4 system.
We've had an ongoing problem with a particular workstation not being able to silence a process alarm. The Operator can acknowledge the alarm but occassionaly the sound will continue, with no alarm on the Alarm List. We've restarted the Workplace & Workstation and recently replaced the station with a spare. The other stations using the same AS & CS (via Load Balancing) do not share the same issue.
Has anyone else experienced this?
Any guidance would be appreciated.
