How does this help you with QET? QET is compatible with DXF files. You can use the DXF files downloaded from Siemens, along with free conversion tools, to create your own custom QET elements.
The "i" typically refers to a of QElectroTech. While the official QET project is excellent, several community-driven repositories use the "i" (Industrial) prefix to denote a version pre-loaded with industrial automation libraries—specifically Siemens, Schneider, and Allen Bradley.
: Search for "Siemens library" or "S7-1200" on the QET Forum to find threads where users attach zipped libraries.
Pre-labeled input and output points matching real hardware. i qelectrotech siemens library free
Drag-and-drop integration for complex devices like the S7-1200 or S7-1500 PLCs saves hours of manual vector drawing. Where to Find Free Siemens Libraries for QElectroTech
: Once loaded, you can search for "Siemens" in the elements panel and drag the symbols directly onto your schematic. QElectroTech Key Siemens Components Available The community collections frequently include: and S7-1500 series modules : Basic and Comfort Panels (e.g., KTP700, TP700). Networking : Scalance switches and Sinumerik components. Switchgear : Contactors, circuit breakers, and power supplies (SITOP). Share the elements library (Page 1) - QElectroTech
Because QElectroTech is open-source, its ecosystem relies heavily on community contributions and shared repositories. You can access free Siemens symbols through three primary sources. 1. The Official QElectroTech Elements Collection How does this help you with QET
Search GitHub for keywords like qelectrotech-siemens-library or qet-elements-siemens .
Pre-made symbols adhere to standard sizing conventions, keeping your electrical schematics organized and easily readable by panel builders.
| Problem | Solution | | :--- | :--- | | | QET uses SVG graphics. Right-click the symbol → Edit Symbol . The "i" library is vectorized; if bitmap, re-download from a trusted source. | | Cannot find the S7-1500 CPU 1518. | The free library focuses on common CPUs (1511, 1513, 1516). You must edit an existing 1516 element and rename it to 1518. (Right-click → Edit → Save As). | | The terminal numbers on the SIRIUS contactor are wrong. | Lock the element, then use Insert > Text to overlay the correct terminal IDs (A1, A2, 13, 14). | | My library disappeared after an update. | Always backup the folder: C:\Users\[YourName]\QElectroTech\elements . The "i" version does not auto-migrate. Copy your old Siemens folder into the new install. | The "i" typically refers to a of QElectroTech
Using a pre-built Siemens library offers several distinct advantages:
QElectroTech makes it incredibly easy to add custom libraries without overriding your core system files. Follow these steps to import your downloaded Siemens elements: Step 1: Locate Your User Collection Folder
To get the most out of your newly installed library, implement these professional drafting habits: Use Master/Slave Relationships for Contactors
