Based Arduino Ethernet shield the Mega 2560 working as Modbus TCP server. My Project configure Mega 2560 as follow:
- Respond to Modbus Master for 100 data including Hold and Input Register (100 x 100)
- Exchange data by I2C Protocol to I2C master from PIC18F4620 (Universal board)
- Support CCSC compiler for bootloader over telnet
I will post full code, schematics and some mod in the arduino library soon.
I am sorry because postpone for Lunar Newyear
