    Is it possible to get CodeSys working with Beckhoff IO cards connected directly to the CX9240 running Linux?

    yes, you need to install Control RTE CX.
    In that package there is the Internal EthercatMaster / EthercatMasterSoftmotion which you could add then.

    Control RTE is for Windows. @arj3090 specified Linux.

    I installed Linux ARM SL and it recognizes the RJ45 ethernet ports, but I cannot get it to recognize the internal port for the IO cards.

    Now I understand. I always thought this was not supported. I might test it later. Thanks.
