    Hi,

    I'm trying to read analog inputs on a Modbus RTU device.

    The COM Port doesn't work.

    I added the SysCom in CODESYSControl_User.cfg.

    Any suggestion?

    Best Regards
    Thanks

    did you try Com Port number 2 in codesys. Because Com port 1 is used for the rs232 console port.

    Hi,

    i fixed the problem.

    In CODESYSControl_User.cfg i setted

    [SysCom]
    Linux.Devicefile=/dev/ttyUSB

    instead of

    [SysCom]
    Linux.Devicefile=/dev/ttyRS485

    and it's working fine.

    Best regards
