Hi...

I am new to the OPC subject. I have a couple of questions regarding the communication between OPC client and OPC server.

What is the mode of communication between the OPC server and client? I am writing a C++ application which interacts with the OPC client. What will be the mode of communication between the OPC client and the C++ application?

Thanks in advance...
