The story of the QElectroTech Siemens Library is one of community collaboration meeting industrial engineering. It highlights how open-source enthusiasts and professionals have made high-end Siemens PLC (Programmable Logic Controller) components accessible to everyone for free. 1. The Open-Source Foundation In 2007, two French students founded QElectroTech
(QET) to create a free, professional-grade tool for electrical diagrams. Unlike expensive proprietary software, QET was built on the GNU/GPL license
, meaning the software and its vast collection of symbols are free to download, use, and modify. 2. Bridging the Gap to Siemens i qelectrotech siemens library free
While QET grew to include over 8,000 symbols, specialized industrial parts like Siemens PLCs
(S7-1200, S7-1500, etc.) were originally hard to find in a standardized format. Community Contribution
: Users and partner companies began creating and sharing custom Siemens elements. The Siemens Open Library : Collaborations, such as the Siemens Open Library
(developed by DMC, Inc. and Siemens Industry), released open-source blocks and documentation for public use. Integration
: Dedicated contributors now maintain repositories on platforms like
where users can download specifically formatted Siemens components to drop directly into their QET projects. 3. How the "Free" Library Works Today
For a modern engineer, using the Siemens library within QElectroTech typically follows this path: Official elements collection for QElectroTech. - GitHub
Finding a dedicated Siemens library for QElectroTech (QET) is straightforward because the software is free and open-source, and many Siemens-specific symbols are already integrated into the standard installation. 1. Built-in Siemens Collection
Most users do not need to download a separate library. Recent versions of QElectroTech (such as v0.8 and higher) have significantly expanded their manufacturer-specific folders.
Location: Open the Elements Panel on the left. Navigate to the Electric folder, then look for subfolders labeled by manufacturer or specific automation types.
Included Elements: You can find Siemens-related symbols for S7-1200 PLCs, sensors, and logic elements directly in the default collection. 2. Community and Official Repositories
If the specific component you need isn't in the default list, the community maintains expanded libraries on GitHub:
Official Elements Collection: This is the primary source for all elements included in the software. You can "git pull" this to your local folder to ensure you have the latest updates.
User Contributions (Contrib): This repository contains additional manufacturer references that might have been excluded from the main distribution to keep it lightweight.
Forum Downloads: The QElectroTech Elements Forum is a goldmine for specific part numbers. For instance, users have shared dedicated collections for Siemens S7-1200 PLCs and Sinamics V90 drives. 3. How to Install New Siemens Elements
If you download a .elmt file (the XML-based format used by QET) or a folder of symbols, follow these steps to use them: Finding free Siemens libraries for QElectroTech (QET) is
Locate the User Collection: Go to your computer's user directory for QET (usually Documents/QElectroTech/UserCollection on Windows).
Copy and Paste: Drop the new Siemens folders or files into this directory.

The fluorescent lights of the university computer lab hummed in a frequency that always gave Elias a headache. It was 2:00 AM, three hours before his final capstone project was due.
On his screen, the schematic for an automated bottling plant lay dormant, a mess of unconnected lines and generic blocks. His professor, Dr. Aris, had been notoriously vague about the requirements, but one thing was clear: the simulation had to run on the Siemens PLC platform, and it had to use specific library blocks for motor drives and safety interlocks.
Elias clicked on the "Libraries" tab in his TIA Portal software. Empty.
He cursed under his breath. He had spent weeks designing the logic, assuming the university computers would have the full suite of Siemens add-ons. They didn't. He was missing the qelectrotech integration pack—a specific set of macros and function blocks that allowed the PLC logic to interface with the electrical schematic drawings he had painstakingly created in QElectroTech, an open-source CAD tool.
Without that library, his schematics were just pretty pictures, and his PLC code was a brain without a body. The simulation would fail.
Elias pulled out his phone, his thumbs flying across the screen in a desperate fugue state. Search: "i qelectrotech siemens library free"
The results were a mess of dead forums, broken links to Russian file-hosting sites, and paywalls. The official Siemens mall wanted $200 for the integration pack—money a student who ate instant noodles for dinner didn't have.
He clicked through pages of forum posts from 2014. "Does anyone have the backup for the QET integration DLLs?" "Link dead." "Try the Siemens support portal." "Just buy the license, pirate."
Desperation began to set in. The cursor blinked on his half-finished code. He was about to fail.
Then, on the third page of results, buried in a thread about legacy automation hardware, he found a comment from a user named PLC_Guru_99.
"If you're looking for the QET legacy libraries for educational purposes, check the Internet Archive. I uploaded a backup of my 2015 image. It's not cracked, it's just the driver files. You'll need to manually path the inclusion folder, but it works for local simulation."
There was a link.
Elias hesitated. Downloading random zip files from the internet onto a university machine was a good way to get expelled for malware distribution. But he had no choice. He clicked the link. The download bar crept across the screen. qelectrotech_siemens_lib_educational.zip. A collection of QET (QElectroTech) symbol files (
He unzipped the folder. It wasn't an installer; it was a raw dump of files. .dll files, .xml descriptors, and a readme text file.
The readme was simple: "Copy to C:\Program Files\Siemens\TIA Portal\Include. Restart TIA. Open the Generic Library Manager and point it to the Include folder. Don't distribute commercially."
Elias’s heart hammered against his ribs. He dragged the folder over. Windows asked for administrator permission. He held his breath and clicked 'Yes'.
He restarted the heavy Siemens software. The splash screen glowed white. The project loaded.
He went to the library manager. He clicked "Add new library." He navigated to the folder he had just pasted. For a second, nothing happened. Then, a new icon appeared in the tree structure: QElectroTech_Integration_V14.
It expanded. Blocks appeared: QET_Motor_Start, QET_Safety_Interlock, QET_Signal_Lighting.
They were there. They were free. And they were exactly what he needed.
For the next two hours, Elias worked in a trance. He dragged the blocks into his ladder logic. He connected the tags to the addresses in his CAD drawing. The QElectroTech software on his second monitor synced up beautifully; as he wrote the code, the CAD software recognized the logic addresses, illuminating the wires in the schematic as if they were live.
By 4:45 AM, the project was complete. He hit "Compile." No errors.
He hit "Start Simulation."
The virtual bottling plant on his screen roared to digital life. Conveyor belts spun. Sensors blinked green. The safety interlocks engaged perfectly, mimicking the safety zones drawn in the CAD schematics.
Elias sat back, exhausted but relieved. He hadn't paid a cent, but he had paid with his sanity.
At 9:00 AM, standing in front of Dr. Aris, he presented the project. "Good," the professor grunted, looking at the simulation. "I see you got the libraries working. Most students give up and hard-code the logic. They fail." "I found a workaround, sir," Elias said carefully. Dr. Aris peered at the screen, looking at the library path. "Internet Archive?" "Yes, sir." The professor cracked a rare, tired smile. "Good man. The 'free' route is usually the hardest path. You learned more doing that than the students who just clicked 'download' on the official store. A-."
Elias walked out into the morning sun, his headache finally fading. He had the library, he had the grade, and he had a valuable lesson in the chaotic, underground economy of industrial automation software.
What “Siemens library for QElectroTech” usually means
- A collection of QET (QElectroTech) symbol files (.qet or within the app’s library structure) representing Siemens products: contactors, circuit breakers, PLC modules (S7-1200/1500), motor starters, sensors, drives (Sinamics), and panel components.
- Often provided as pre-drawn symbolic blocks (single-line or multi-line) with attributes for part numbers, references, technical specs, and footprints for panel layout.
Part 6: Why "Free" Beats Paid (For Prototyping)
You might wonder: Why use a free Siemens library when Siemens provides TIA Selection Tool and EPLAN macros?
Here is the reality for freelance engineers and small panel shops:
- EPLAN costs thousands per year – QET is $0.
- TIA Selection Tool does not generate schematics – It specs parts but doesn't draw wiring.
- AutoCAD Electrical requires subscriptions – QET runs offline, forever.
The "i qelectrotech siemens library free" solution gives you 90% of the functionality for 0% of the price. You can wire a full S7-1500 panel with ET200SP remote I/O and Sinamics drives without ever paying a license fee.
2.2 “Electrotech”
This term likely refers to “electrotechnology” or electrical engineering. Several training institutes and small software vendors use “Electrotech” in their names. There is no Siemens product or official library with this name.
