OPC Tunneller from MatrikonOPC (with encryption and data compression) provides an easy, reliable and secure way to communicate between networked computers. It does away with the headaches typically associated with DCOM configuration.
While DCOM requires a reliable communication network, OPC Tunneller operates under poor initial network setup, widespread networks, and unreliable network infrastructures such as satellite or wireless networks. OPC Tunneller even allows for user configurable time-outs, thus giving you complete control.
