Hello Markus,
could you please be more specific about what exactly is not working? Please check the proper connection of A and B signals. Also please check the RS485 termination resistor – this shall be done externally. Also check the communication speed and all commands.
Sometimes it is good to use some USB-RS485 converter and try it via PC so you are sure that you fully understand the communication and the PoStep is working and then connect the Controllino.
