Hello,
I’ve been working without any issue for a few weeks connecting VC with a virtual S7-1500 via OPC-UA but some days ago I started having a connection issue:
“An unexpected error occurred while reading node metadata attributes from the server.”
Since this happen I haven’t been able to add new variables and I can see the main structure of the OPC but not access to the variables.
With an external OPC client I can see those variables without any problem.
I’m using VC 4.3 Premium edition, I’ve tried with VC4.2 and the same issue is reported.
Any ideas?
Regards!
