In distributed process control systems, sensor-t o-control room connections is inevitable as networking technologies advance and several network protocols are proposed for plant floor control systems. Therefore, we analysis protocols such as ARCnet, CAN, MAP, Field Bus and SCRAMnet + in terms of real - time capability and guarantee of high reliability. Although these protocols adapt protocol schemes for real - time and deterministic communication characteristic in nature, one needs thoughtful selecting criteria for high reliable applications such as nuclear power plant and time critical manufacturing plants.
