Design of EtherCAT Slave System Based on Zynq-7020 Chip

EtherCAT provides clear advantages of fast speed, flexible topology, accurate synchronization and efficient communication. To meet the needs of high-speed and real-time communication of servo motors, a Zynq-7020 chip from Xilinx and an ET1100 chip from Beckhoff are used to establish a new slave system. Hardware, software and design process are analyzed. Through a series of tests on the slave station, it has been proved that the I/O communication between the master and the slave is fast, the synchronization performance is good, and the slave system works stably under the EtherCAT protocol.
