User-contributed Siemens PLC element libraries for QElectroTech are primarily sourced through community forums and specialized GitHub repositories, supplementing the software's built-in collection. These libraries, often featuring Siemens S7-1200 or Sinamics V90 components, can be integrated into the software by placing the downloaded .elmt files into the User Collection directory.

QElectroTech offers a free, open-source library with extensive Siemens components for industrial automation, though users report issues with inconsistent symbol sizing and metadata duplication. While the software enables professional documentation, managing its large, community-driven collection often requires manual organization and custom element creation.

The QElectroTech Siemens Library is a specialized collection of digital symbols and elements used within QElectroTech (QET), a free and open-source CAD software for creating industrial electrical diagrams. This library specifically provides standardized components for Siemens industrial automation products, allowing engineers and students to design professional-grade schematics including PLCs, motor starters, and HMI displays. Core Components of the Siemens Library
The library is part of the broader QET Elements Collection, which contains over 8,000 symbols. Siemens-specific elements typically found in this library include:
PLCs and Controllers: Symbols for the S7-1200, S7-1500, and Logo! series, including input/output modules.
Protection Devices: Circuit breakers, thermal relays, and residual current devices like the Siemens Sirius line.
Control & Signaling: HMI touch screens (ecran IHM tactile) and pilot lights.
Switchgear: Disconnecting switches and contactors essential for motor control circuits. Key Features for Professional Design
Using the Siemens library in QElectroTech offers several technical advantages for industrial documentation:
Cross-References: Automatically updated links between related elements (e.g., a contactor coil and its associated contacts). i--- Qelectrotech Siemens Library -
Bill of Materials (BOM): Elements come with predefined metadata like manufacturer, article number, and order number, which can be exported to a .csv nomenclature for procurement.
Open XML Standard: All elements are stored in a human-readable XML format, making it possible to create or modify custom Siemens symbols using the built-in Element Editor.
Multi-Platform Support: The library works seamlessly across Windows, Linux, and macOS versions of the software. How to Install and Use the Library Share the elements library (Page 1) - QElectroTech
The "story" of the QElectroTech Siemens Library is one of community-driven engineering and open-source collaboration. It isn't a single official product, but rather a collection of contributions from engineers worldwide who use QElectroTech
—a free, open-source CAD software—to document industrial automation projects involving The Evolution of the Library
The project began as a way to provide a libre alternative to expensive proprietary software for creating electrical, hydraulic, and pneumatic schematics. Over time, the library has grown to include over 8,000 symbols, with a significant portion dedicated to major manufacturers like Siemens. Community Origins : The Siemens-specific elements, such as S7 PLC modules HMI panels , were largely developed by users on the QElectroTech Forum Standardization
: Engineers within the community, such as users Bernard Andre and scorpio810, have worked to standardize the size and connection points of Siemens PLC symbols to ensure consistency across different projects.
: While the official collection is read-only, users can create and share their own custom "User Collections" for specific Siemens components that might not be in the base software yet. How the Library is Used Today
Today, the Siemens library within QElectroTech allows professionals and students to build complex technical manuals with automated features: QElectroTech Tutorial 01 Introduction Standardized function blocks : The library provides a
Integrating Siemens components into QElectroTech (QET) involves sourcing .elmt files from the QET community, importing CAD data via DXF/SVG, or using the Element Editor to create custom symbols. The process involves copying element files into the QET configuration directory, which can be managed directly through the QET Element Editor and library collection system. You can find more information on the QElectroTech Gallery, the Siemens Image Database, and the Siemens CAx Download Manager.
Introduction
In the realm of industrial automation and process control, the need for standardized communication protocols and libraries has become increasingly important. One such library that has gained significant attention in recent years is the IEC 61804, also known as the Electrotech Siemens Library. This library is a comprehensive collection of function blocks and data types designed to facilitate communication between devices and systems from different manufacturers. In this essay, we will explore the IEC 61804 library, its significance, and its applications in the field of industrial automation.
Background and Development
The IEC 61804 library was developed by the International Electrotechnical Commission (IEC) as part of its efforts to standardize communication protocols for industrial automation and process control. The library is based on the IEC 61131-3 standard, which defines the programming languages and data types for programmable logic controllers (PLCs). The IEC 61804 library provides a set of standardized function blocks and data types that enable devices and systems from different manufacturers to communicate with each other seamlessly.
Key Features and Benefits
The IEC 61804 library offers several key features and benefits that make it an attractive solution for industrial automation and process control applications. Some of the key features include:
The benefits of using the IEC 61804 library include:
Siemens Library
Siemens, a leading manufacturer of industrial automation and process control systems, has implemented the IEC 61804 library in its products. The Siemens Library provides a comprehensive set of function blocks and data types that are compatible with the IEC 61804 standard. The library is designed to facilitate communication between Siemens devices and systems, as well as with devices and systems from other manufacturers that also support the IEC 61804 standard.
Applications and Future Directions
The IEC 61804 library has a wide range of applications in industrial automation and process control, including:
In the future, the IEC 61804 library is expected to play an increasingly important role in the development of industrial automation and process control systems. As the library continues to evolve, it is likely to include new function blocks and data types, enabling even greater levels of interoperability and system flexibility.
Conclusion
In conclusion, the IEC 61804 library, also known as the Electrotech Siemens Library, is a comprehensive collection of function blocks and data types designed to facilitate communication between devices and systems from different manufacturers. The library offers several key features and benefits, including standardized function blocks, data types, and device and system interoperability. As the library continues to evolve, it is likely to play an increasingly important role in the development of industrial automation and process control systems.
Unlike commercial software, QET does not auto-install a massive vendor library. The community maintains it. To access the Qelectrotech Siemens Library, follow these protocols:
