This project demonstrates a Modbus/TCP server that runs STM32H735G-DK evaluation board.

Instructions to run the demo:

- Compile the project and run a debug session
- Connect a terminal (115200 bauds, no parity, no flow control) to the virtual COM port of the ST-Link to output log messages
- Plug Ethernet cable
- The board acquires an IPv4 address (using DHCP), a link-local IPv6 address and a global IPv6 address (using SLAAC)
- Pick up the IP addresses in the logs (the IP addresses are also displayed on the LCD)
- Connect to the Modbus/TCP server using its IP address (using Modbus Poll for example):
	- Coil 0 can be written to change LED2 state
	- Coil 1 can be written to change LED3 state
	- Coil 10000 can be read to retrieve USER button state
	- Register 30000 can be read to retrieve USER button state
	- Register 40000 can be written to change LED2 state
	- Register 40001 can be written to change LED3 state
