EtherCAT Raspberry Pi

    Hi all,

    I am working on etherCAT communication and have just started using CODESYS. I would like to know if it is possible to create a ethercat master using CODESYS on the PC and configure a raspberry PI as a slave device and setup a communication system between them. If yes, please guide me on how it can be realized.

    Hi Aron,
    without additional hardware it is not possble to have an EtherCAT Slave on Raspberry PI.

    There are manufacturers specific Ethernet/EtherCAT adaptors, as for example the EK1100 from Beckhoff, which and at least with me worked fine. However you should be aware that since Raspberry PI has just 1 Ehternet port, you need an additional Ethernet port in order to have your PI-PLC connected with the LAN, and an USB/ETH adaptor did the job for me.
