Sorry, I don’t speak German language, hope you don’t mind I ask in English.
Since documentation is in German, I still not sure is there support for serial port for Modbus functions… Twincat (don’t know for Codesys) support only physical port on motherboard, which my laptop lack, so I USB-serial which is not supported.
So, my question is network.lib support Modbus serial on usp<>serial driver, and if not, is possible to write that support.
Regards!
