I need help with the steps to implement Modbus RTU on the OPTA using ladder or FBD programming. I haven't found any information about this on the forum, the internet, or anywhere else.
Please, maybe someone can help with it, so what would help is an example of how Modbus master and Modbus slave would be implemented.

I suggest to give a look at this tutorial: https://docs.arduino.cc/tutorials/opta/pmc-opta-temp-ctrl
Have a good day,
