ctrlX I/O RS485/422 or RS232 how to use them for serial communication with Node-RED or Bosch Device Bridge or Python?

ctrlX I/O cards XI522001 for RS485/422 or XI521001 for RS232 give a serial communication capability to our ctrlX threw an Ethercat network. How can I use these interfaces to manage a serial communication with Node-RED and other apps like Bosch Device Bridge or a Python application?

For exemple in Node-RED, there are a native serial communication blocks :

These blocks need some parameters like : serialport, serialbaud, databits, parity, stopbits... Usually parameter serialport is something like : /dev/ttyUSB0 but for our ctrlX I/O communication cards, I don't know what to set. Do you have an idea?

Thanks for your help
