摘要
EtherCAT是一种新型实时工业以太网总线。研究了EtherCAT工作原理、通信协议、性能和冗余技术。设计了基于EtherCAT冗余技术的多轴网络运动控制系统,采用TwinCAT作为主站,利用ET1100和TMS320F28335开发了EtherCAT从站设备,构建了一主多从的EtherCAT网络结构,并给出了系统硬件和软件的设计方案,以实现伺服控制和实时数据传输。
EtherCAT is a new real-time industrial Ethernet Fieldbus.The EtherCAT＇s architecture,the working principle,communication specification,performance and redundancy are studied.Multi-axis network motion control system are designed base on EtherCAT redundancy,together with a slave device by ET1100 and TMS320F28335,and a master by TwinCAT,which can construction a EtherCAT network structure with one-master and more-slaves.The hardware and software design of the servo system is given,which realizes the real-time data transmission and servo control.
