Most complete Modbus library for Arduino. A library that allows your Arduino board to communicate via Modbus protocol, acting as a master, slave or both. Supports network transport (Modbus TCP) and Serial line/RS-485 (Modbus RTU). Supports Modbus TCP Security for ESP8266/ESP32.

ModbusTools are cross-platform (Windows, Linux) Modbus simulator tools (client and server) with GUI to work with Modbus protocol (TCP,RTU,ASCII)

Open ModSim is a Free Modbus Slave (Server) Utility

This is an Arduino library that implements the slave/server logic of the Modbus RTU protocol.

Modbus TCP client library to interact with Modbus servers such as PLCs.

Modbus master and slave implementation in C++

Modbus TCP/IP server that translates incoming requests to RTU and relays them to configured serial device.

A basic Modbus TCP Master example written in C++ on the ESP32 hardware using the CAS Modbus Stack

Modbus TCP implementation based on FreeRTOS and LwIP

modbus client and server library for kotlin

Modbus TCP Client/Server

ModbusBridge is a simple cross-platform (Windows, Linux) Modbus converter/gateway application that provides interconvertions between different types of Modbus protocol: TCP, RTU, ASC

Modbus simulator CLI is a high-performance modbus TCP server with customizable simulation. Available as CLI tool or as docker image
