The Application and Research of EtherCAT redundancy in Multi-axis Network Motion Control System
Weiguang Li · Modular Machine Tool & Automatic Manufacturing Technique · 2012
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.
