Currently, the most requested sub-library is the Siemens S7-1500 line. Here is how to install a high-quality community library.
A pro-tip for advanced users: QElectroTech is not TIA Portal (which generates schematics automatically via HWConfig), but it is incredible for as-built documentation.
The Workflow:
This allows you to click on a symbol in QET representing a Siemens 3RV2 circuit breaker and instantly see the upstream/downstream wiring—something even expensive software struggles with. i--- Qelectrotech Siemens Library -
Siemens provides multiple libraries:
If you meant electrotechnical CAD library (symbols/macros for Siemens devices), the process differs from PLC software libraries.
If your symbols show a red "X" or a missing "i" (interface) icon, the XML pointer is broken. This usually happens if the element was saved with absolute paths. Currently, the most requested sub-library is the Siemens
Fix: Open the .elmt file in Notepad++. Look for <inputs> and <outputs>. Change any full C:\Users... paths to ./ (relative paths).
The library aims to:
QElectroTech is an open-source, cross-platform application designed for drawing electrical schematics. One of its most powerful features is its modular element library system. This allows you to click on a symbol
The Siemens Library within QElectroTech is a dedicated collection of schematic symbols and macro elements representing Siemens AG automation and electrical components. It allows engineers and electricians to rapidly design control panels, PLC systems, and power distribution networks using standardized Siemens equipment.
The library is categorized to streamline the design workflow. While the exact contents may vary based on the version of QElectroTech or custom community contributions, standard inclusions typically feature:
