KRC4 EtherCAT Bus with two or more devices

  • Greetings


    I am currently designing a fieldbus architecture and would like to know if I have no inconvenience in using two or more remote I/O modules under the EtherCAT bus using a small industrial switch for it. I have worked in the past with only one Weidmüeller module. Currently I have one Weidmüeller remote I/O module and another one from a welding system manufacturer that also has its configuration file. I intend to use the EtherCAT bus of the KRC4 and connect it to a switch where the two mentioned devices are located. Is there any restriction for this?


    Thanks in advance

  • don't use ethernet switch. that will save few $$.

    connect nodes according to manufacturer recommendations.

    in case of EtherCat, this means daisy chaining nodes. the physical connections must match topology in WoV

    1) read pinned topic: READ FIRST...

    2) if you have an issue with robot, post question in the correct forum section... do NOT contact me directly

    3) read 1 and 2
