I am working on an alarm management project connecting to a GE Workstation OPC AE server to fetch all the alarm and event data.
I noticed that the NewState and the SubCondition alarm attribute from the OPC AE raw does not reflect the actual alarm state from the WorkstationST alarm viewer when we simulated an alarm. The documentation doesn't tell you much. Having said that, I would expect that the OPC AE server comply with OPC AE 1.1 standards but apparently is not.
Appreciate if someone can shed some lights on this.
