Mastering QElectroTech: How to Integrate the Free Siemens Library (i QElectroTech Siemens Library Free)

By [Your Name/Team] | Updated: October 2024

In the world of electrical engineering and automation, two names command respect on opposite ends of the budget spectrum: Siemens, the premium industrial automation giant, and QElectroTech (QET), the open-source, community-driven schematic software.

For years, a gap existed between professional-grade Siemens component libraries and free software. Engineers using QElectroTech often found themselves manually drawing PLCs, contactors, and drives. That stops today.

If you have searched for "i qelectrotech siemens library free" , you are looking for the holy grail of open-source automation design: a ready-to-use, comprehensive collection of Siemens symbols, footprints, and elements for QElectroTech. This article provides exactly that—a complete guide to downloading, installing, and optimizing the free Siemens library for QElectroTech.

How to Install the Siemens Library in QElectroTech

Once you download the file (usually a .qet or .elmt file or a compressed .7z folder), follow these steps:

Open QElectroTech.
Go to File > Open Collection (or press Ctrl+Shift+O).
Navigate to the downloaded folder. Do not unzip individual elements unless specified.
Select the collection file (e.g., Siemens_S7_Collection.qet).
The library will appear in your left-side "Elements" panel under a new tab.

Step 5: Adding the "i" Touch – Custom Toolbars

The "i" version is famous for a custom toolbar. Replicate this:

Right-click the top menu bar → Configure Toolbars.
Create a new toolbar called "Siemens iQET" .
Drag your most-used Siemens elements (S7-1200 CPU, 3RT contactor, Sinamics G120) from the collection panel into the new toolbar.
Save the configuration.

Tip 2: Creating Dynamic Labels

Standard Siemens library elements often have generic text. Use QET’s dynamic text feature:

Click on the Siemens PLC symbol.
Insert %folio for page number and %position for element coordinates.
This mimics the behavior of EPLAN. (The "i" version often pre-configures this.)

3.1. Siemens S7 PLCs (The Crown Jewel)

S7-1200 series (CPU 1211C, 1212C, 1214C) with all digital and analog expansion modules (SM 1221, SM 1222, etc.).
S7-1500 series (CPU 1511, 1513, 1516) including interface modules and technology modules.
ET 200SP distributed I/O stations (IM155-6 PN ST, BaseUnits, IO modules).

Final Verdict

Functional but flawed. The free Siemens library for QElectroTech keeps the software usable for low-budget Siemens projects, but lack of official maintenance means you will spend time fixing or creating symbols yourself. For serious Siemens design, invest in dedicated tools.

DRAFT REPORT

Title: Assessment and Acquisition of Siemens Library for QElectroTech (Open Source)

1. Executive Summary This report investigates the availability, licensing, and installation methods for Siemens symbols and libraries compatible with QElectroTech, a free and open-source computer-aided design (CAD) software. As QElectroTech does not include a native, comprehensive Siemens library by default, users requiring Siemens-specific schematics must utilize community-sourced collections or create custom elements. This report outlines the current status of free Siemens libraries and provides a roadmap for implementation.

2. Introduction QElectroTech is widely used for creating electrical schematics due to its zero-cost nature and cross-platform compatibility. However, industrial users often require manufacturer-specific symbols (e.g., Siemens PLCs, HMIs, Motor Starters) to streamline the design process. This report addresses the common query regarding the existence of a "free Siemens library" and evaluates the feasibility of integrating these assets into the QElectroTech workflow. i qelectrotech siemens library free

3. Findings

3.1. Native Availability

The standard installation of QElectroTech includes a generic IEC library.
While these generic blocks can represent Siemens hardware, they do not possess specific pinouts, part numbers, or visual fidelity to Siemens products (e.g., specific shapes of LOGO! modules or S7-1500 PLCs).

3.2. Community and Open Source Libraries

GitHub Repositories: Several open-source repositories contain user-generated Siemens symbols. These are generally free to download but vary in quality and adherence to standards.
QElectroTech Forum/Wiki: The official community forums host threads where users share custom collections.
Licensing: Most community-generated libraries are released under Creative Commons or GPL, making them free for commercial and private use, provided attribution is given where required.

3.3. Official Siemens Resources

Siemens provides CAx data (CAD files) for their products via the Siemens Industry Mall or "SIRIUS" download centers.
Compatibility: These files are typically exported in formats like DXF, DWG, or specific formats for commercial software (e.g., EPLAN, TIA Portal). They are not natively formatted for QElectroTech (.elmt format). Conversion is required.

4. Technical Implementation

To utilize a "free" Siemens library in QElectroTech, two primary methods are available:

Method A: Importing Community Collections (Recommended)

Locate a trusted repository (e.g., via GitHub or the QElectroTech community "Elements" download section).
Download the collection folder (usually a .zip file).
In QElectroTech, open the Panel (left side) and right-click the root folder or a sub-folder.
Select Import -> Import a directory.
Navigate to the extracted Siemens library folder to integrate it into the local collection.

Method B: Creating Custom Elements from DXF/DWG

Download the 2D CAD footprint (DXF format) from the official Siemens support site.
In QElectroTech, open the Element Editor.
Use the Import DXF function (if available in the version) or copy/paste vector lines from a CAD viewer.
Add electrical connection points (terminals) manually.
Save the new element as a .elmt file in a custom "Siemens" folder.

5. Limitations and Risks

Accuracy: Community libraries may contain errors in pin numbering or spacing. Verification against official datasheets is mandatory.
Metadata: Free libraries often lack embedded metadata (manufacturer info, article numbers), requiring manual data entry in the project's parts list.
Versioning: QElectroTech file formats evolve; very old community libraries may require updating to function correctly with newer QElectroTech versions (0.8+ or 0.9+).

6. Conclusion A direct, official "Siemens Library" plugin for QElectroTech does not exist. However, "free" resources are available through the open-source community. The most efficient workflow involves importing community-verified collections as a baseline and supplementing them with manually created elements derived from official Siemens DXF drawings for specific, non-standard components.

7. Recommendations

Audit Existing Assets: Check the QElectroTech "Download" page on the official website first, as it aggregates user contributions.
Standardization: Establish a dedicated "Siemens" folder within the QElectroTech collections directory to house imported and custom elements.
Contribution: If high-quality custom Siemens elements are created, contribute them back to the QElectroTech repository to improve the ecosystem for future users.

Disclaimer: This report is for informational purposes. Users must verify the licensing of any downloaded CAD assets to ensure compliance with open-source and copyright regulations.
