Simulated industrial control system with Modbus TCP/IP and web HMI to manage air conditioning units.

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

Golang Modbus Server (Slave)

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

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

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.
