MODBUS RS485 Communication Between Client and Server Using Arduino Board

MODBUS RS485 Communication Between Client and Server Using Arduino Board

Use the Simulink® Support Package for Arduino® Hardware to implement a MODBUS® RS485 asynchronous, serial communication between MODBUS client and server. It also shows the four modes of operation: Client Read, Client Write, Server Read, and Server Write.
