摘　　要：基于实时以太网的运动控制系统以其高可靠性、快速性和稳定性等优点成为运动控制系统的发展趋势,EtherCAT作为目前最快的工业以太网标准,已经被越来越多的应用在各种实时控制系统当中。提出了一种以NetX500芯片为核心的EtherCAT网络接口模块方案,该接口模块不仅兼容EtherCAT主站和从站通信功能,而且采用并行接口,几乎能与所有主控系统芯片相连。采用netANALYZER实时以太网分析仪和Wireshark软件对接口模块进行了EtherCAT网络通信测试,测试结果表明该接口模块具备良好的EtherCAT网络实时通信能力。The motion control system based on real-time Ethernet has become a trend for its high reliability,speed and stability. As the fastest industrial Ethernet standard,EtherCAT has been more and more applicated in a variety of real-time control systems. This paper presents a EtherCAT network interface module program based on NetX500. The module is not only compatible with the EtherCAT master and slave communication function,but also using a parallel interface,which is suitable for almost all the main control system chips. A Real-time Ethernet analyzer named netANALYZER and the software Wireshark are applied to test the network communication of this module. The test results verify that the module has excellent EtherCAT network real-time communication capabilities.
