Hello, I'm trying to get Messages and Alarms of a Siemens OPC UA Server (SINUMERIK 840dsl). I've done this with a EVENT-Node of the "node-red-contrib-opcua" library. If I start my flow everything works well and I get my Messages and Alarms. But after this first start my OPC UA Server Crashes and is no longer reachable. I already tried to fix the Problem with the LocaleIds array in the ActivateSessionRequest Method, to send a ["en-us"] back instead of an empty array. But this also changes nothing.
Has anyone the same issue with the Siemens OPC UA Server or does somebody know how to fix it? Or is there any limitation with events? Because I get about 30 Messages at the beginning.
The whole process works with the UaExpert.
