      Yes, the order and type of all io-modules is what's needed. At least for a start. Afterwards, with a bit of training and courage, you might be able to modify the configuration yourself.

      Best regards,

        This is my current setup (....with some second hand modules from ebay... 🙂 )

        I also did an export description to XML from the BK9000. At the moment I don't have another bus coupler but as far as I understand the documentation then the BK9000 is also supporting Ethercat.....

          Hi,
          the XML does not contain any information about the individual I/O modules. Can you please try again and export a complete description?

          As for the BK9000 coupler, AFAIK it does not support EtherCAT. Can you provide a link to the documentation which you mentioned?

          Best regards,
          Jaroslav

            Maybe I mixed things up....nevertheless Beckhoff is mentioning that the BK9000 is supporting 'Beckhoff real-time ethernet' which I tought is the same as EtherCAT.

            Also in the documentation of the BK1120 Beckhoff is refering to the BK9000, altough I don't completely understand what they mean with this.....

              I am expecting a BK1120 to arrive by the end of next week. So better to postpone everything until then....

              BTW, the link to the YouTube video isn't working for me....

                Hi,
                the video link should work now, thanks for reporting it.

                As for the BK9000, "Beckhoff real-time Ethernet" is not EtherCAT, therefore it is not EtherCAT compatible. You need the mentioned BK1120 for that so you are on the right track.

                Once it arrives, import the whole setup into TwinCAT and upload the project here.

                In the meantime, you can make the I/Os work in REXYGEN via BK9000 and Modbus TCP.

                Best regards,
                Jaroslav

                  Modbus TCP I already managed , it only took me quite some time before I figured out how the addressing is working.

                  To use Ethercat on the RasPi I will need a dedicated ethernet port I guess, correct?

                  Grtz,

                  Kris

                      Hi Kris,
                      thanks for the Twincat file. My colleagues are neck-deep in other ongoing projects at the moment so the preparation of REXYGEN project will take some time. Hopefully in the next week. I'll get back to you.

                      Kind regards,
                      Jaroslav

                        No problem, it is only for some hobby-related stuff so no rush.

                        Grtz,

                        Kris
