What is OPC Tunnelling?

OPC Tunneling means connecting an OPC Server to an OPC Client over a network, using TCP/IP as the transport protocol. This means you can avoid the problems associated with configuring DCOM to work over a network. You also eliminate the long DCOM timeouts that can effectively shutdown your application.
