Arduino Modbus is a protocol used to communicate between a Modbus master device and a Modbus slave device over a serial communication line. The Arduino board can act as both a master and a slave device, depending on the application.
Modbus is a simple and widely used protocol in the industrial automation sector that enables communication between devices, such as programmable logic controllers (PLCs), sensors, and other industrial equipment. Modbus is designed to be a simple, reliable, and robust communication protocol, making it ideal for use in industrial environments.
The Arduino Modbus library allows users to easily implement Modbus communication on their Arduino board. The library supports several Modbus functions, such as reading and writing digital and analog inputs and outputs, as well as reading and writing holding registers and input registers.
To use the Arduino Modbus library, users need to connect their Arduino board to a Modbus network using a serial communication line. The Arduino board can then be programmed to act as a Modbus master or slave device, depending on the application. The library provides easy-to-use functions to read and write Modbus data, making it simple to implement Modbus communication on an Arduino board.
