My issue is that I only have one usb port and thus only one config node can connect to it at any given time both my serial node and modbus node need their config node to be connected to the usb port for the node to work.
I do know a easy fix is to have 2 usb to rs485 converter so I have 2 usb port that both config node can be connected to but the whole point of RS485 is that I can have 1 port to control 255 devices over some distant using wires. I am using less than 255 devices so if I have more than 1 usb to rs485 converter it seems strange.
This is my flow

I also asked this qn on this topic but I repost this qn using the modbus tag
