  • Method and device for exchanging data on the basis of the OPC communications protocol between redundant process automation components
    Patent number: 8132042
    Abstract: The invention relates to a method and a device for exchanging data on the basis of the OPC communications protocol, wherein at least one OPC-ready server is connected parallel to a master OPC server. An OPC client is connected to the master OPC server over a first communications link and to at least one OPC-ready server via at least one second communications link. The OPC client exchanges data over the first communications link and the master OPC server, and over at least the second communications link and at least one OPC-ready server with automatic devices, and evaluates the data transmitted by the master OPC server and at least one OCT-ready server. In the event of failure, the master OPC server is at least partially switched over from the OPC client to at least one OPC-ready server such that the program continues to run smoothly in the same place.
