IEDExplorer
IEC61850 IED Explorer in .net
IEDExplorer is an IEC 61850 client tool written for testing and educational purposes. IEDExplorer can connect to an IEC61850 device (also called an IED) over MMS (ISO/IEC9506-1 and ISO/IEC 9506-2) communication protocol. The tool is written in pure C# including the MMS ASN.1 parser (based on BinaryNotes ASN.1 tool) and runs in .net environment, on Windows. Linux/Mono support has been lost on the way (volunteers welcome). See Features for what the tool can do for you. I will appreciate your help in testing and extending the tool! -

OSHMI - Open Substation HMI
SCADA HMI for substations, IoT and automation applications
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 a toy project! It's been actually used in dozens of substations up to 230kV level and also in control centers with configurations up to 70.000 tags. Feel free to ask questions in the "Discussion" section.

JQM Java Quine McCluskey
JQM - Java Quine McCluskey for minimization of Boolean functions.
Java Quine McCluskey (JQM) implements the Quine-McCluskey algorithm with Petrick’s Method for minimizing Boolean functions. Designed for both education and industrial application, it handles up to 16 variables and functions. Uniquely, JQM bridges the gap between theory and practice: it visualizes the solution process with generated Karnaugh Maps for students, while supporting PLC engineers by exporting results to Structured Text (ST) and Ladder Diagram (LD). The software includes a GUI for managing truth tables and supports diverse file formats for import and export.
