I would Like to connect with fornius solar inverter through MODBUS TCP with arduino to READ and WRITE register value only. I want to set Arduino as Master and Inverter as slave and I want to use only two functions "Read Holding Registers" and "Write Single Holding Register" function code '3' and function code '6' respectively. Is there any good and working Library available for these? and also an example.
