AN-359 Monitoring EtherCAT telegram using WIRESHARK
EtherCAT uses a standard Ethernet telegram and the EtherCAT protocol type is recognized by most Ethernet monitoring software. When connecting a system together, it is often necessary to monitor the telegram traffic and see how the EtherCAT master and slaves are interacting.
