Data handshake method based on EtherCAT protocol

摘要

PROBLEM TO BE SOLVED: To provide a data handshake method based on an EtherCAT protocol applied to an EtherCAT slave device. SOLUTION: The method is to generate a post-processed data packet by receiving a data packet from a immediately preceding device and acquiring self-data or inserting feedback data into the data packet, and immediately after processing the post-processed data packet. Transmitting to the device, receiving the return packet sent back from the device immediately after, transmitting the return packet to the device immediately before, packet distribution to at least one of the data packet, the processed data packet and the return packet. Run the program to generate and analyze backup packets in which at least part of the content is the same as data packets, processed data packets or return packets, and to filter the specified application data of other slave devices from the backup packets. including.
