Reply To: Modbus communication via Controllino

I’ve also tried the simple_master Code from GitHub – smarmengol/Modbus-Master-Slave-for-Arduino: Modbus Master-Slave library for Arduino but the response I get is are weird signs and question marks. I’ve changed the address etc. in the Code to the numbers I have (in DEC) but it won’t work and I don’t know what the problem is.
