Good morning,
I am performing model changes at runtime on my Prosys SDK (v3.1.2) based OPC UA server (adding/deleting reference in this case) and trigger a custom subtype of a GeneralModelChangeEvent after the change has been applied.
—–
Edit: I removed the original problem description (the client received the modelChangeEvent but didn’t see the actual addressSpace changes) as the problem was found to be with the OPC UA client.
—–
Occasionally, the modelChangeEvent is missing the subscriptionId, which causes some problems at the client side. The missing subscriptionId has been confirmed using WireShark for monitoring the communication.
Regards,
Hans-Uwe

Hi,
Just to be sure, by “subscriptionId” do you mean the PublishResponse.subscriptionId (in the spec v.1.04 Part 4 Table 95 “Publish Service Parameters”) or something else?
If that is the case I assume “missing” means 0. Does the ResponseHeader.serviceResult of the PublishResponse show a Good StatusCode?
