If you cannot find a specific Siemens component, QET provides tools to create or adapt your own:
QElectroTech is a free, open-source application for creating electrical, electronic, automation and control circuit diagrams. Many users look for component libraries — especially manufacturer libraries like Siemens — to speed up diagram creation. This post explains what to expect when seeking a “Siemens library” for QElectroTech, how to find and install available resources, legal and compatibility considerations, and practical alternatives.
This is the primary hub for shared components. Users frequently post .elmt files for Siemens hardware in the Elements Forum . Specifically, a dedicated thread for Siemens Elements has existed for years and continues to be updated by specialists.
Open a Siemens contactor element ( 3RT2017-1AB01 ). Go to . You will see fields like reference and manufacturer . Add your internal stock codes here. This allows QET to generate automatic Bill of Materials (BOM) reports.

(S7-1200, S7-1500, etc.) were originally hard to find in a standardized format. Community Contribution
If you find a .elmt file or a folder of Siemens symbols online, follow these steps to use them: : Windows : %APPDATA%\qet\elements Linux/Mac : ~/.qet/elements
. This open-source electrical CAD software relies on an extensive network of automation professionals who actively contribute pre-built component files ( .elmt ). These files cover popular hardware lines like the Siemens S7-1200, S7-1500, LOGO! Modules, Sirius contactors, and SITOP power supplies .
Because QElectroTech is fully open-source (GNU/GPL), components are not locked behind corporate paywalls. You can source official and community-built Siemens libraries from three primary hubs: 1. The Official QET Elements Submodule Share the elements library (Page 1) - QElectroTech
To utilize a "free" Siemens library in QElectroTech, two primary methods are available:
To unlock the full potential of these tools, follow these steps:
(developed by DMC, Inc. and Siemens Industry), released open-source blocks and documentation for public use. Integration
Pre-made symbols adhere to standard sizing conventions, keeping your electrical schematics organized and easily readable by panel builders.
The standard QElectroTech installation includes a "User Collection" and a "QElectroTech Collection." Over the years, the core development team has integrated hundreds of standard Siemens components directly into the default software download.
