This allows you to click on a symbol in QET representing a and instantly see the upstream/downstream wiring—something even expensive software struggles with.
The application relies on an , meaning all component data, terminal nodes, and graphical lines are stored in highly portable text files. Anatomy of the QElectroTech Siemens Library
This means that any fresh installation of QET 0.100 or later comes with a baseline of Siemens symbols built-in. You can typically find these pre-installed elements in the "Siemens" folder, located within the "Articles constructeurs" (Manufacturer Articles) section of your element collection. However, a known limitation is that you may find the standard library lacking specific, modern components like the ET 200SP distributed I/O module or a specific SIMATIC power supply.
The future of Siemens components in QET looks bright, driven by community growth and technical improvements. i--- Qelectrotech Siemens Library -
Elements come with predefined metadata like manufacturer , article number , and order number , which can be exported to a .csv nomenclature for procurement.
This is the built-in, master directory that comes with the software. It contains thousands of standardized European and international symbols organized by category (e.g., Contacts, Protections, Motors). You cannot modify this collection directly.
This specialized library enables electrical engineers, control panel builders, and automation technicians to design precise electrical schematics using free software. Instead of drafting complex Programmable Logic Controllers (PLCs), contactors, or variable frequency drives (VFDs) from scratch, users can drop pre-configured Siemens components straight onto their digital canvas.

Users often share their custom collections on the official QET forum. For example, a collection for the Siemens LOGO! API is provided as a .zip file that can be downloaded and installed. Here's how you can install one:
The official QET library, actively managed and updated, is your first and most reliable source for industrial components. The project's changelog for version (released February 2026) explicitly states: "New elements added for industrial and automation workflows (including Siemens-related elements , logic elements, sensors and Arduino components)".
Once you've populated your library, placing and connecting Siemens components is straightforward. However, it's important to understand the two types of representations you might encounter in the community collections: You can typically find these pre-installed elements in
The QElectroTech Siemens Library provides a specialized collection of over 8,200, mainly community-contributed, electrical symbols for PLC modules like the S7-1200 and LOGO! series to support detailed industrial documentation. Users can expand the default, read-only collection by downloading elements from the QElectroTech community forum or creating custom symbols using the built-in element editor, as discussed on the QElectroTech Forum QElectroTech QElectroTech: Welcome, presentation
