Design and Application of Communication Gateway of EPA and MODBUS on Electric Power System

Through the research of EPA Industrial Ethernet technology, MODBUS fieldbus technology, ARM embedded system and μC/OS-II real-time operating system, this paper discusses how to design and develop communication gateway of EPA and MODBUS. The communication gateway can realize bidirectional data transceiving on EPA protocol and MODBUS protocol. The communication gateway can provide a stable, secure, real-time and flexible solution for process control of the power plant.
