  • Method for the fail-safe operation of a process control system with redundant control devices
    Patent number: 10372095
    Abstract: A process control system is provided which has at least one OPC client and one OPC server which communicate via a standardized OPC interface. Furthermore the process control system has at least two redundantly operated control devices which each communicate with the OPC server by means of a coupling device. Each control device is designed to provide process variables and status information. The status information contains the current role of the respective control device, wherein the current role is either that of a main control device or an auxiliary control device. The OPC server is designed to detect the main control device in response to the status information of at least one control device, to register a list of variables generated by the OPC client at the main control device and/or to transmit to the OPC client only the process variables which have been provided by the main control device.
