Now with IEC61850 support! This project combines existing open source projects and tools to create a very capable, mobile and cloud-friendly HMI system that can rival proprietary software. This approach makes it possible to join forces of each project (Chromium, SVG/HTML5, PHP, Lua, SQLite, Inkscape, Lib61850, OpenDNP3, Nginx, Vega, PostgreSQL, Grafana,…) to achieve a great set of open, evergreen, modular and customizable tools for building great HMIs for automation projects. This is not...

Note: The project has moved to https://github.com/pyhys/minimalmodbus The files available here are very old, download from Github instead. MinimalModbus is an easy-to-use Python module for talking to instruments (slaves) from a computer (master) using the Modbus protocol, and is intended to be running on the master. Example code includes drivers for Eurotherm and Omega process controllers. The only dependence is the pySerial module (also pure Python). This software supports the ‘Modbus RTU’ and ‘Modbus ASCII’ serial communication versions of the protocol, and is intended for use on Linux, OS X and Windows platforms. ...

Logo2Modbus is a C# Modbus/TCP Slave for Logo, a mini PLC manufactured by Siemens. You can use it to built a visualisation of your home automation application. Over the Modbus/TCP protocol you can use the process values in many HMI/SCADA systems.
