    Hello,

    I've noticed a problem with ethercat devices scan.
    The system can't find all the devices really present.
    Using twincat, the same group of beckhoff I/Os is recognized and complete.
    In Codesys 3.15.20 I've loaded all the beckhoff XML, but some terminal in codesys are ignored.
    Someone can help me?

    Thanks
    Cosimo

    Hello Edwin,

    the PLC is based on Raspberry Compute module 3, with Codesys Control for Raspberry PI MC SL.
    I've tryed with different ethernet usb dongle and with the onboard ethernet but unsuccessful.
    I've loaded all the updated XMLs files.
    And I haven't found any error from the PLC logger.
    Also I've re-installed the OS, but the problem is the same.
    Using a PC with twincat I can see all the modules.

    I'm loosing my hair...

    Thanks
    Cosimo

    Hello Edwin,

    I've found the problem.
    One terminal was defective.
    Sorry for the inconvenient.

    Thanks
