Abstract
A method for data hand-shaking based on EtherCAT protocol is disclosed, the method is implemented by an EtherCAT slave device, and includes: receiving a data packet from a previous device; obtaining self-related data from or inserting feedback data to the data packet for generating a processed packet; transmitting the processed packet to a next device; receiving a returned packet from the next device; transmitting the returned packet to the previous device; performing a packet diversion procedure to at least one of the data packet, the processed packet and the returned packet for generating a backup packet, wherein at least part of the content of the backup packet is identical to the content of the data packet, the processed packet or the returned packet; analyzing the backup packet; and, filtering the backup packet for obtaining designated application data with respect to other EtherCAT slave devices.
