Re: Cannot connect to OPC Server

Post by Uauser3456 »

I could not find the way to enclose the message screenshot.
I am using the TPsOPCServer class with C++ Builder
an external OPC UA server is running and operative, I can connect with UA Expert without problem
If I put the correct host name in the host property and try to connect , I have an error message :
Cannot connet to OPC server \\opc.tcp://192.168.10.241\:Server Name cannot be converted to a valid ClassID

Can you help me ?
Thanks
