External alarm references not working
Hey
I'm using the external alarm service in 5.1 and cannot get the "acknowledged" digital output in external alarm configuration to work.
The "audible alarm" output works fine and can write to a variable but the acknowledged cannot write to any variable.

Try writing to a General Property as a test - if this works you have an issue with the destination OPC server. Try checking the [Workplace Structure]Web System Workplace:Operator Message List for OPC server write issues, eg lack of permission or data type incompatibility.
If the GP remain stable you have most likely missed something in the configuration or misunderstood when the system write to the acknowledged signal.
