Modbus.Net was open sourced two years ago when I graduated. The first target of this project was to implement remote PLC communication using Modbus TCP. Half a year later the company decide to use a IoT hardware, then a more universal architecture was required. The main platform changed to a universal communication platform. Despite all these changes the name "Modbus.Net" stuck.

The real Modbus Implementation has been moved to Modbus.Net.Modbus. If you want a real Modbus C# implementation, please download Modbus.Net and Modbus.Net.Modbus at the same time.

There is also Modbus.Net.Siemens that can communicate with Siemens S7-200, S7-200 Smart, S7-300, S7-400, S7-1200 and S7-1500 using PPI or TCP/IP.

Supported Platforms
