The library is extensive, but focuses heavily on automation components: A. Siemens S7 PLC Modules
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 availability of Siemens components in QET can be categorized into three main areas: official releases, community contributions, and user-created libraries. Your access to these resources will depend on your version of QET and your engagement with the community.
| Component Series | Specific Examples / Variants Found | Key Notes | | :--- | :--- | :--- | | | Basic Module, digital expansion modules | Available as "Master" elements | | S7-1200 PLC | S7-1214C DC/DC/DC, S7-1215C DC/DC/RLY | EPLAN-style elements available | | S7-1500 PLC | S7-1500 modules | Requested by users for creation | | ET 200SP | 6ES7 155-6AR00-0AN0 (ET 200SP interface module) | Manual creation guide available | | SIMATIC Power Supplies | 6EP3436-8SB00-0AY0 (24V DC power supply) | Manually created by users | | Siemens LOGO! | LOGO! with expansion modules | Limited "realistic" symbols, recommended for panel views, not wiring diagrams | i--- Qelectrotech Siemens Library -
Enhancing Electrical Schematics with the QElectroTech Siemens Library
Once you've populated your library, placing and connecting Siemens components is straightforward. However, it's important to understand the two types of representations you might encounter in the community collections:
For engineers, electricians, and automation professionals, few names carry the weight of Siemens. As a global leader in industrial automation, Siemens provides the backbone for countless control systems, from simple programmable logic relays (LOGO!) to high-end programmable logic controllers (PLCs) like the S7-1200 and S7-1500. When creating professional electrical documentation, having accurate symbols for these components is not a luxury; it's a necessity. The library is extensive, but focuses heavily on
The library contains not only pure graphical symbols but also intelligent elements that support , dynamic texts and automatic conductor numbering . They are often divided into:
PLC CPUs, digital input/output modules, and analog modules. SIMATIC HMI: Basic and Comfort panels. SINAMICS Drives: Frequency converters.
Here's a step-by-step guide based on a real-world example of creating a Siemens ET 200SP analog input module: Your access to these resources will depend on
The software also stores such as manufacturer, article number, description and a reference to a parts list (Bill of Materials) inside the elements. A complete CSV export of all used components is available, which makes it easy to generate a bill of materials.
Users often share their custom collections on the official QET forum. For example, a collection for the Siemens LOGO! API is provided as a .zip file that can be downloaded and installed. Here's how you can install one:
