FED:high performance industrial fieldbus based on Ethernet devices

  • Received Date: 29 Feb 2012

  • A kind of high-speed real-time fieldbus used in automation equipment named fieldbus based on Ethernet devices(FED) was studied. FED is based on Ethernet components and FPGA chip. System on chip(SOC) technology was used to develop a kind of practical FED device. Without complex driver, media access control layer communication was realized. The application layer protocol can be designed for different control tasks. FED performs at 100 Mbit/s on summation frame and employs "data operation on fly" technology. Master-slave structure is used in FED which supports one master and 255 slaves. The prototype system proves that FED can meet the high-speed and real-time requirement of industrial automation equipment.
