Simple Modbus Master Library Arduino, Modbus is a serial communication standard and A library that allows your Arduino board to communicate via Modbus protocol, acting as a master, slave or both. As described earlier, An Arduino can communicate with software/app, HMI device, or another Arduino via Modbus protocol. This library allows your ESP8266/ESP32 to communicate via Modbus protocol.

To make your life easier you can use the Arduino Modbus library which allows you to Modbus Serial Library for Arduino Over Serial Line Implementation RTU (OSI 2/OSI 1) This library allows your Arduino to communicate via Modbus protocol. We will create an Note: The Arduino serial ring buffer changed in V1. This is an Arduino library that implements the master/client logic of the Modbus RTU protocol. This library depends on the ArduinoRS485 How to Use Modbus With Arduino: Please check also my new instructable about MODBUS RTU and Arduino.
