    Hi,

    so far I have only used one com port - built-in interface in RPi - RS232 (dev/serial0) as COM1 in Codesys, and my CODESYControl_User.cfg have congiuration like below:

    [SysCom]
Linux.Devicefile=/dev/serial
portnum := COM.SysCom.SYS_COMPORT1

    Actually I added to my Rpi Hat with 2xRS232 (SPI). - /dev/spidev0.0 and /dev/spidev0.1

    How I should change my CODESYControl_User.cfg file to use added porta as COM2 and COM3 in Codesys ?

    /dev/spidev0.0 and /dev/spidev0.1 are SPI interfaces - so you could not map them to
    serial ports that way.

    The serial port:

    [SysCom]
    Linux.DeviceFile.1=/dev/serial0

    for Com1
