QElectroTech (often shortened to QET) is a free software application designed for creating complex electrical diagrams for various industries. Built on the Qt framework, it supports the creation of schematics for hydraulics, pneumatics, building automation (domotics), and, most importantly for this guide, industrial automation. Elements and diagrams are stored using the XML format, making them highly portable and easy to manage. qelectrotech siemens library

Always verify the terminal numbering against the official Siemens datasheet, as community-made symbols may occasionally have variations in terminal spacing.

A: Yes. QET is free and open-source software (FOSS) distributed under the GNU General Public License (GPL) . All official and community libraries are also typically free to use and share. : Unzip the contents to access the element folders (e

The library is organized to mirror real-world industrial panels:

Using detailed Siemens-specific element collections—ranging from to SIRIUS motor starters —helps you bridge the gap between open-source drafting software and proprietary industrial hardware ecosystems. The Importance of the Siemens Element Library Built on the Qt framework, it supports the

Drawing each input/output channel group or terminal module as a separate element. This is the preferred method for high-density systems like the Siemens S7-1500. It allows you to distribute input and output cards across different pages of your schematic document. Utilizing Master/Slave Links

To maintain a well-organized library, the community often discusses guidelines for structuring symbols. Key considerations include:

Use the to add the branding and part number (e.g., "SIEMENS" and "6ES7214-1AG40-0XB0").

When symbols are pre-configured with Siemens part numbers, descriptions, and manufacturing data, QElectroTech can automatically generate a flawless, production-ready BOM.
