The QElectroTech Siemens Library enhancement focuses on standardizing and integrating high-quality Siemens PLC symbols directly into the official element collection. Recent updates have addressed long-standing issues with symbol scaling, terminal spacing, and duplicated entries to provide a more "fixed" and professional library for industrial automation design. Key Improvements in the Siemens Library
Standardized Scaling: New Siemens PLC symbols follow a consistent grid size, ensuring that complex modules—like the S7-1200 or S7-1500 series—align perfectly with standard wire connections in a diagram.
Optimized Terminal Spacing: To improve legibility in dense PLC I/O diagrams, terminal spacing for Siemens elements is now set to a minimum of 40 (with a preference for 60), compared to the standard 20 used for simpler components like contactors.
Library De-duplication: Developers have worked to remove redundant or triple-listed elements in the official collection, keeping only the most accurate version in the designated Siemens folder.
Automatic Project Integration: Elements used from the Siemens collection are automatically copied to the Project Collection. This ensures the diagram remains functional and editable even if the file is shared with a user who doesn't have the same external libraries installed. How to Access and Use the Fixed Elements
Open the Collections Panel: Navigate to Settings > Display > Collections to ensure the panel is visible.
Locate Siemens Elements: Browse the QET Collection tree (typically under Automation > PLC > Siemens). Deployment in Projects:
Drag and Drop: Simply pull the desired PLC module into your workspace.
Overwrite Existing: If you have an older, "broken" version of a symbol, you can drag the updated one over it. A popup will ask if you want to overwrite the symbol, which updates all instances of that element throughout your project.
Shared Company Libraries: For professional environments, sysadmins can host a "fixed" common Siemens collection on a network share. Launch QElectroTech with the --common-elements-dir= option to point all workstations to this centralized, verified library.

To update your QElectroTech (QET) library with Siemens-specific elements or resolve "fixed" issues with missing components, you should focus on using the latest official releases and the community-maintained repositories. ** Siemens Elements in QElectroTech**
Recent versions of QElectroTech have integrated a significant number of industrial automation symbols, including Siemens-specific PLCs and logic modules. Integrated Library : Check the Automation > PLC
folder in your QET element panel. This section typically contains common Siemens S7 series (S7-1200, S7-1500) components and LOGO! modules. Official Downloads
: If your local library is missing specific Siemens parts, you can download the latest collection directly from the official QElectroTech download page External Repositories
: For specific, high-detail Siemens panel layouts that might not be in the default package, users often share "fixed" or expanded collections on the QElectroTech forum Updating and Fixing the Library
If you are experiencing issues with "broken" or missing Siemens symbols, follow these steps to "fix" your local library: Normalization & Cleanup qelectrotech siemens library fixed
: Recent updates to the QET source mirror included a cleanup of element metadata, including article numbers and descriptions for manufacturer-specific fields like Siemens. Updating your software version often fixes these metadata gaps. Import Custom Elements Once you download a
file (element) or a folder of elements, drag and drop them into the "Imported" collection in your QET interface.
This creates a duplicate copy that you can edit or customize using the built-in Element Editor
if the default terminal spacing or labelling needs adjustment. Terminal Spacing Fixes
: For Siemens PLCs or I/O modules, the community recommends a terminal step of at least 40 to 60 units

"QElectroTech Siemens Library – Fixed"
If you need more context or a slightly expanded version for a release note or forum post:
The "fixed" Siemens library for QElectroTech (QET) typically refers to community-driven efforts to standardise and correct the official collection's Siemens PLC symbols, which previously suffered from scaling and terminal alignment issues. Recent Fixes and Library Status
As of early 2026, significant updates have been integrated into the QElectroTech 0.100 release and development versions to address long-standing library inconsistencies:
Standardised Grid Alignment: Key fixes ensure that terminal X,Y positions follow a multiple of 10, with a 20-unit step for common elements and 40–60 units for complex PLC I/O symbols.
Scale Adjustments: Recent patches (January 2024 and onwards) resized various graphic components to reflect scale changes, specifically targeting industrial automation workflows including Siemens and Arduino components.
Metadata Cleanup: Article numbers, manufacturer fields (like "Siemens"), and descriptions were normalised during import to ensure consistent search results. S7-1200 Specific Updates
: Community contributors have released "fixed" .elmt files for popular Siemens hardware, such as the The "fixed" Siemens library for QElectroTech (QET) typically
(1212 and 1214 DC/DC/DC models) and associated digital I/O modules. Where to Find the Fixed Elements
Users looking for the most stable and "fixed" versions of Siemens symbols should check these primary sources:
Official QET Elements Collection: Managed on GitHub (qelectrotech-elements), this repo receives the most vetted updates.
User-Contributed Collection: The qelectrotech-element-contrib repository contains many manufacturer-specific fixes that may not yet be in the main stable branch.
QET Community Forum: The Siemens S7-1200 PLC topic is a major hub for sharing individually "fixed" symbols for specific Siemens modules. Manual Fixes for Users
If you encounter older symbols that are not yet updated, the community recommends the following "manual fixes" via the Element Editor:
Terminal Spacing: Ensure PLC I/O terminals are at least 40 units apart for better readability.
Remove Duplicates: The official library sometimes contains triple-duplicated Siemens elements; users are advised to delete redundant versions to avoid confusion.
Generic Templates: Instead of maintaining separate symbols for every Siemens amperage (e.g., 5A, 10A), use one master symbol and edit the reference field manually. Official elements collection for QElectroTech. - GitHub
QElectroTech Siemens element library is a community-driven collection of symbols for Siemens PLCs (like the S7-1200 and S7-1500) and other industrial components. Recent reviews and user discussions highlight its value as a free alternative to expensive proprietary software like EPLAN, though it requires some manual management. Helpful Review & Insights
Users generally praise the library for its breadth but note that "out-of-the-box" perfection varies. QElectroTech Breadth of Symbols : The library includes specific Siemens hardware like the 6ES7-214-2AD23-0XB8 and various PLC I/O modules. Accuracy and Fixes
: Some users have reported issues with "wrong names" or duplicated elements in the official collection. A common "fix" suggested by the community is to clean up your User Collection
by keeping only the reference caliber you actually need rather than every variation (e.g., 5A, 10A, 20A). Workflow Tips Grid Alignment
: For terminals, ensure the X,Y position is a multiple of 10 to snap correctly to the grid.
: Use a terminal step of 20 for standard components (breakers, contactors) and 40–60 for more complex PLC I/O to avoid overcrowding. Importing Elements it fails to resolve element references.
: While QET doesn't have a one-click "sync" for unofficial libraries, you can manually download files from the elements_contrib repository and copy them into your local User Collection QElectroTech Key Resources Official Elements Collection : You can browse or contribute to the main library on the QElectroTech GitHub Repository Community Forums QElectroTech Forum

The QElectroTech community has responded enthusiastically to the Siemens library fix. Forums on LinuxCNC, Elektroda, and Reddit r/PLC are filled with relieved users.
The official QET collection relies on community contributions. Siemens libraries from different authors use varying naming schemes (e.g., "SIEMENS_S7-1200" vs "Siemens_S7_1200"). When QET loads the collection, it fails to resolve element references.
