Qelectrotech Siemens Library Instant
To effectively use the QElectroTech Siemens library, users can leverage both the built-in official elements and a wide array of community-contributed symbols to design complex industrial automation diagrams. Understanding QElectroTech Symbol Collections
QElectroTech (QET) organizes its components into three distinct types of collections to manage different manufacturers like Siemens:
Official QET Collection: A read-only database provided with the software. It contains thousands of standardized symbols, including essential electrical and logic components.
User Collection: A personal space where you can create, edit, or import custom Siemens elements.
Project Collection: Automatically stores any element used within a specific project file, ensuring portability even if the original library is missing on another computer. Accessing Siemens Elements in QElectroTech
While the Official QElectroTech Repository includes generic electrical symbols, specific manufacturer libraries like Siemens are often expanded through community efforts: qelectrotech siemens library
Check Built-in Categories: Look under the "Electric" and "Logic" folders in the standard collection for common PLC, motor, and converter symbols.
Community Contributions: The QElectroTech Forum hosts specific threads dedicated to Siemens elements where users share custom-made PLC I/O modules and contactors.
Third-Party Repositories: Sites like GitHub often host "contrib" libraries containing Siemens S7-1200 or S7-1500 symbols. How to Import Custom Siemens Libraries
If you find a Siemens library folder (containing .elmt files), you can add it to your setup: Official elements collection for QElectroTech. - GitHub
6. Embedding Wiring and Addressing Conventions
- Include default wiring connection points with clear anchor nodes so wires snap reliably.
- Predefine addressing placeholders using token syntax (e.g., %ADDR%) so users can run find/replace or scripts to fill addresses.
- Provide example wiring snippets:
- PLC digital input wiring with sensor, fuse, and terminal block.
- Motor starter wiring with overload, contactor, and FWD/REV wiring options.
- Offer standard terminal numbering templates that map to Siemens terminal block conventions (e.g., X1.1–X1.8).
17. Example Project Checklist
- Choose library version and copy to project folder.
- Set project tag/addressing scheme.
- Place core hardware symbols (PLC, PSU, I/O).
- Wire signals through terminal blocks and mark wire numbers.
- Populate symbol metadata (Tag, PartNumber).
- Generate BOM and perform review.
- Produce final PDF and panel layout exports.
18. Conclusion
A Siemens-focused QElectroTech library, properly organized and maintained, streamlines automation design, improves consistency, and supports downstream processes (procurement, panel building, PLC programming). Prioritize clear metadata, consistent naming and addressing, and lightweight, well-tested symbols to maximize effectiveness. To effectively use the QElectroTech Siemens library ,
Appendix (suggested next steps)
- Build a minimal starter library with a CPU, one DI module, one DO module, power supply, and a contactor, then expand iteratively.
- Create a sample project demonstrating complete I/O mapping and BOM export to validate workflows.
Developing a Siemens library QElectroTech (QET) involves integrating high-quality, standardized symbols for industrial automation components. While QET includes a massive Official Elements Collection
, specialized Siemens-specific libraries often need to be custom-built or imported to match technical manuals. 1. Structure the Siemens Library
Organize your Siemens content into logical subcategories within the User Collection to simplify navigation: PLCs & Modules : S7-1200, S7-1500, and ET 200SP distributed I/O. HMI Panels : Comfort and Basic panels. Drives & Starters : SINAMICS G120 series and SIRIUS motor starters. Switchgear : SENTRON circuit breakers and contactors. 2. Element Creation Workflow To develop specific Siemens components like the SIMATIC S7-1200 Base Template : Right-click an existing PLC element and select Edit element to use it as a foundation. SVG Import
: For "fancy" or highly detailed elements, you can create the visual base in external SVG editors and import them into the QET Element Editor Pin Mapping Include default wiring connection points with clear anchor
: Ensure terminal numbers (e.g., L+, M, I0.0) match the official Siemens Technical Documentation
: While QET doesn't have a traditional "group" function, unselecting "Maintain visual rotation" for text fields keeps labels aligned during rotation. 3. Management and Sharing Storage Location : In Windows, your custom Siemens elements are stored in %APPDATA%\qet Collaboration : Use GIT to manage your library. You can clone the official repository
to keep basic elements updated while maintaining your Siemens additions in a separate branch. Project Specifics : Note that once an element is used, it is copied into the Project Collection
, making the project file portable even if the recipient lacks your Siemens library. 4.
