have you tried the
official Arduino Modbus TCP library ? We do not need to write our own library, because the CONTROLLINO is compatible with the Arduino boards – in this case CONTROLLINO MAXI/MEGA = Arduino Mega/Mega2560 + Ethernet Shield (the first version with Wiznet W5100).
Please, share with us the results!
