Hi all, I would like to understand how to use properly the EoE functionality. If I am not wrong the EtherCAT Master could act as a bridge between an Ethernet Network (let’s say connected to NIC_1) and the EtherCAT one (let’s say connected to NIC_2).
My doubt is about the procedure that the Master has to perform. Basically I don't understand how the Master decides to forward a certain Ethernet frame to a certain EtherCAT slave. Example: 1) An application (used for commissioning) running on an external PC wants to communicate with a certain slave. 2) The application send the Ethernet frame to the NIC_1 of the EtherCAT Master 3) The Master has to "split" the Ethernet frame into one or more EoE frames and send them (through NIC_2) to the right slave. How the Master knows to which slave it has to send the EtherCAT datagrams containing the EoE fragments? Reading the code I see that inside the function ec_master_eoe_thread() the Master runs the EoE state machine of the EoE handler of each slave but I am a bit in trouble understanding how and why the data are forwarded properly, as explained previoulsy. Thanks in advance, Regards Luca
