QElectroTech + Siemens Library — Making Industrial Schematics Smarter

When you’re designing electrical schematics for industrial automation, clarity and reuse matter. QElectroTech is a lightweight, open-source diagram editor built for electrical, electronic and automation schematics. Pairing it with a curated Siemens-style library (symbols, function blocks, device templates) brings professional polish, speeds design, and reduces errors. Here’s an engaging, practical blog post you can publish.

Conclusion: Build, Share, Automate

The qelectrotech siemens library is not a product you can buy – it is a resource you cultivate. By investing time in creating accurate, well-organized Siemens elements, you transform QElectroTech from a generic drawing tool into a professional-grade automation design suite.

Final Action Plan:

  1. Download QElectroTech 0.9 or later.
  2. Visit the official QET forum to download any community Siemens elements.
  3. Create a folder called Siemens_Industrial in your user library.
  4. Spend 1 hour creating three critical components (e.g., S7-1200 CPU, a 3RV breaker, a G120 drive).
  5. Save these as your "Base Template."
  6. Share your creations back to the community!

With a robust Siemens library, you can produce error-free, professional electrical schematics faster than ever – all with zero software licensing cost.

Visuals are key: Attach a screenshot of a completed S7-1500 rack or a detailed schematic page using these elements.

Source Verification: If you are looking for existing libraries, check the QElectroTech Forum where users frequently share "S7-1200" and "S7-1500" collections.

Compatibility: Remind users that QET elements are saved in XML format, making them easy to edit in the built-in Element Editor if they need to tweak a specific part. Elements (Page 1) - QElectroTech

The story of the QElectroTech (QET) Siemens library is a prime example of open-source collaboration, where a community-driven project rose to meet the needs of industrial professionals seeking free alternatives to expensive proprietary software. The Genesis of QElectroTech

The journey began in 2007 when two French students, Xavier and Benoit, founded QElectroTech as a tool for creating complex electrical schematics. Although the original founders left in 2013, a global community of developers and electrical engineers took over, evolving the software into a robust CAD/CAE editor. Bridging the Industrial Gap

As QET grew, users working with high-end industrial hardware—particularly from Siemens—needed standardized symbols to document their systems.

A Massive Collection: Today, the official collection exceeds 8,000 symbols, covering electrical, logic, pneumatic, and hydraulic systems.

Vendor-Specific Additions: Recent updates (such as version 0.100) specifically highlighted the addition of Siemens-related elements, logic sensors, and Arduino components to better support industrial automation workflows. The User-Driven Library

What makes the "Siemens library" unique in QET is its community-curated nature:

Contributions: Many Siemens-specific symbols are created by professional electricians and shared via the QET Official Elements Collection on GitHub.

Customization: Because Siemens hardware varies greatly, users often use the built-in Element Editor to draw their own specific PLC or drive symbols. Once dropped into a project, these symbols can be edited and saved to a personal "User Collection".

Open Standards: Symbols are saved in XML format, allowing for easy modification and sharing across different operating systems (Windows, Linux, and macOS). How to Use the Library Download QElectroTech 0

Engineers typically integrate Siemens components into their projects by:

Searching the Collection: Using the integrated search engine to find "Siemens" or specific part types in the elements panel.

Drag and Drop: Dragging the symbol onto the workspace where it automatically connects to aligned conductors.

Generating Reports: Once the schematic is finished, the Export Nomenclature tool can generate a CSV parts list for ordering the actual Siemens hardware.

Today, the QElectroTech Siemens library continues to grow through an active Forum where users exchange new symbols, ensuring the software remains a viable, professional-quality choice for industrial documentation. Quality of the elements II (Page 1) - QElectroTech

Here’s a helpful overview of the QElectroTech Siemens Library — what it is, where to find it, how to use it, and tips for getting the most out of it.


Part 5: Working with Siemens PLCs – Dynamic Function Blocks

The most powerful feature of qelectrotech siemens library is the ability to create "Intelligent Elements" that mirror TIA Portal addressing.

Example: Simulating an S7-1200 digital input card.

Create a Master element (the card) with n child elements (input channels). In QET, use the "Conductors" linking feature.

  1. Draw the SM1221 8x 24V DC module.
  2. For each input (I0.0 to I0.7), create a terminal link to a generic input symbol placed elsewhere in the schematic.
  3. Add dynamic formula: %autotext to auto-increment tags (I0.0, I0.1...).
  4. Save the library.

Now, dragging one SM1221 from your library instantly places 8 connected inputs on your drawing, with correct Siemens DB/bit addressing.


The Verdict

The QElectroTech Siemens Library is **essential

QElectroTech (QET) is a popular open-source software for creating electrical diagrams, and its Siemens-specific library is a vital resource for engineers working with Simatic PLCs, Sinamics drives, and other industrial automation hardware.

The library is primarily a community-driven collection of .elmt files (XML-based symbol formats) that represent Siemens components according to international standards like IEC 60617. 🛠️ Accessing the Siemens Library

The Siemens elements are not always bundled in the "out-of-the-box" base installation but are readily available through the Official QElectroTech Elements Collection. With a robust Siemens library, you can produce

Integrated Collection: Check the "Common Collection" tab in your QET panel. Look under Automation > PLC > Siemens.

GitHub Repository: For the latest additions (like S7-1200 or S7-1500 modules), users often pull directly from the Official Elements GitHub.

User Contribs: Many niche Siemens parts (e.g., specific Sinamics V90 drives) are found in the User Contribution Repository. 🧩 Key Library Categories

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

PLC Modules: Includes CPUs, Digital Input/Output (DI/DO), and Analog modules for S7-300, S7-400, S7-1200, and S7-1500.

Motor Control: Symbols for Sirius soft starters, contactors, and thermal overloads.

Drives & Inverters: High-detail symbols for Sinamics G120 and S120 series. Power Supplies: Common Sitop power modules. HMI Panels: Graphics for Comfort and Basic touch panels. 📥 How to Add Custom Siemens Symbols

If you have a specific Siemens part not in the default list, you can import it using several methods supported by QElectroTech Documentation:

DXF to ELMT Conversion: Siemens provides .dxf drawings for most parts on their SiePortal (formerly Industry Support). Use the "Import DXF" feature in QET to convert these into editable symbols.

Manual Creation: Use the built-in Element Editor to draw a custom footprint. You can set terminal points (power, signal, ground) so that the "Auto-Link" feature works when you draw wires.

Community Forums: The QET Elements Forum is a hub where users share specific Siemens .elmt files they have created. 💡 Best Practices for Use

Use Project Collections: To ensure your project remains portable, QET copies used elements into a "Project Collection." This prevents broken links if you send the file to someone else.

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

Layer Management: When using complex Siemens PLCs, utilize the "Folio" system to separate power distribution from I/O signal logic.
