Modbus

Modbus プロトコルを使用した通信

Modbus® はクライアント/サーバー アーキテクチャを使用して実装されるリクエスト/レスポンス プロトコルで、これにより Arduino® ハードウェアと周辺デバイスの間の通信が容易になります。

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.
