【摘要】：EtherCAT是一种实时工业以太网协议,使用链路冗余技术是实现链路稳定性和可靠性的重要手段。介绍了基于FPGA的EtherCAT链路冗余原理,设计通过FPGA实现主站与从站、从站与从站之间的通信链路与冗余链路的自动切换,从而实现EtherCAT的链路冗余。通过测试验证了此方法的可行性,增加了EtherCAT系统的可靠性与可维护性。
[Abstract]:EtherCAT is a real-time industrial Ethernet protocol. Using link redundancy technology is an important means to achieve link stability and reliability. This paper introduces the principle of EtherCAT link redundancy based on FPGA, and designs the automatic switching of communication link and redundant link between master station and slave station, slave station and slave station through FPGA, so as to realize the link redundancy of EtherCAT. The feasibility of this method is verified by testing, and the reliability and maintainability of EtherCAT system are increased.
