AC800M Events Problem: Unlegal AssocDescription in EventEnrollment
the AE OPC Server suddenly doesn't forward any Events anymore for one AC800M Controller, and the Controller Log is filled with the following Error:
Unlegal AssocDescription in EventEnrollment
can anyone give me a Hint what could be the Problem?
"Unlegal AssocDescription in EventEnrollment" indicates that there is a corrupt pointer to an AssocDescription in the server side of an event subscription or a corrupt heap element.
Please collect the controller logs and contact the local support organization for further help.
