I--- Qelectrotech Siemens Library - -
Siemens provides multiple libraries:
If you meant electrotechnical CAD library (symbols/macros for Siemens devices), the process differs from PLC software libraries.
Looking for a Siemens symbols library for QElectroTech? I created a comprehensive, well-organized Siemens component library for QElectroTech that includes PLCs, HMIs, contactors, circuit breakers, power supplies, motors, sensors, and terminal blocks — all labeled to match Siemens naming conventions.

QElectroTech (QET) is a powerful, open-source software used to create electrical, pneumatic, and hydraulic diagrams, featuring a growing community-driven library of Siemens components. While QET does not have a single "official" Siemens-only library, it includes many Siemens elements in its default collection and allows users to import or create custom Siemens PLC and automation symbols. The QElectroTech Siemens Library Ecosystem
QElectroTech organizes its massive collection of over 8,000 symbols into tiered collections that provide access to Siemens hardware.
Official QET Collection: This built-in, read-only library includes standard industrial symbols like motors, switches, and contactors compatible with Siemens specifications.
User & Community Contributions: The QElectroTech Forum is the primary hub for downloading specific Siemens libraries, such as the S7-1200 PLC series, which includes detailed elements for modules like the 1214C and 1215C.
Custom Siemens Element Creation: Users can utilize the built-in Element Editor to design proprietary Siemens components that are not yet in the official database, saving them in the XML-based .elmt format. Key Features for Siemens Projects
QET is designed to handle the complexity of industrial automation projects that frequently use Siemens hardware.
PLC Symbol Precision: Dedicated Siemens PLC symbols often feature standardized terminal spacing (often 40 to 60 units) to ensure clear legibility in high-density schematics. i--- Qelectrotech Siemens Library -
Project Management: You can group multiple Siemens-related schematics into a single project, which automatically generates a Bill of Materials (BOM) in spreadsheet format for easy procurement.
Cross-Platform Flexibility: The software and its libraries are available for Windows, Mac OS, and Linux, ensuring compatibility across different engineering environments. How to Add Siemens Elements to Your Library
To expand your QElectroTech library with Siemens-specific parts, follow these steps:
Search the Forum: Visit the Elements section of the QET Forum to find user-contributed Siemens packages (e.g., S7-1500, LOGO! modules).
Import Elements: Download the .elmt files and place them into your local user_elements folder.
Use the Collections Panel: Open QET and navigate to Settings > Display > Collections to see your newly added Siemens components alongside the default library.
Drag and Drop: Simply drag the Siemens symbol from the collection panel directly onto your drawing workspace. QElectroTech: Welcome, presentation Siemens provides multiple libraries:
In the world of free and open-source electrical CAD software, QElectroTech (QET) stands as a formidable alternative to expensive proprietary tools like EPLAN or AutoCAD Electrical. However, the true power of any ECAD software lies in its component libraries. For automation engineers working with German engineering giants, the phrase "i--- Qelectrotech Siemens Library -" represents a critical search for standardization, efficiency, and precision.
This article serves as the definitive guide to understanding, installing, and utilizing the Siemens library within QElectroTech. Whether you are designing a S7-1200 PLC panel, wiring a Sinamics drive, or laying out a Profibus network, mastering this library will cut your design time in half.
QElectroTech is an open-source, cross-platform application designed for drawing electrical schematics. One of its most powerful features is its modular element library system.
The Siemens Library within QElectroTech is a dedicated collection of schematic symbols and macro elements representing Siemens AG automation and electrical components. It allows engineers and electricians to rapidly design control panels, PLC systems, and power distribution networks using standardized Siemens equipment.
| Error Message | Probable Cause | Solution |
| :--- | :--- | :--- |
| Element not found | You moved the .elmt file after drawing it. | Use File > Replace element to remap to the new library path. |
| Terminal 'X1' missing | The slave element (terminal) was not copied with the master. | Ensure the terminals/ folder is in the same directory. |
| Cannot edit Siemens symbol | The library file is read-only. | Right-click the .elmt file > Properties > Uncheck "Read-only." |
| The 'i' icon is grey | The element lacks conductive dynamic endpoints. | Open Element Editor, add dynamic_text to a conductor node. |
When designing PLC racks using the Siemens library, use the Grid function in QElectroTech.
