QElectroTech, or QET in short, is a free software to create industrial complex electric diagrams. QElectroTech Open Project — QElectroTech 2020 documentation
In the humming quiet of a small industrial workshop, Elias sat hunched over his workstation. The glowing screen of his computer reflected in his glasses, displaying the open interface of QElectroTech, the open-source electrical diagram software he had championed for his small team. Open a Siemens contactor element ( 3RT2017-1AB01 )
For weeks, Elias had been meticulously designing a complex control system for a new manufacturing line. The heart of the system was built around Siemens components—S7-1200 PLCs, SITOP power supplies, and SIRIUS motor starters. He knew the hardware inside out, but representing them accurately in his schematics was a different story.
"There has to be a better way than drawing every contactor from scratch," he muttered, rubbing his eyes.
He spent an afternoon scouring the internet, his search queries growing more specific. Finally, he hit the jackpot: "QElectroTech Siemens Library Free."
His search led him to a vibrant community forum where a veteran automation engineer had shared a comprehensive collection of free Siemens symbols tailored specifically for QElectroTech. With a few clicks, Elias downloaded the .elmt files.
As he imported the new library, the "Siemens" folder appeared in his workspace. He dragged and dropped a detailed S7-1200 PLC symbol onto his canvas. It wasn't just a box; it had the correct terminal markings, the status LEDs, and even the subtle Siemens branding. "Perfect," Elias whispered.
The library transformed his workflow. Instead of hours of tedious drafting, he was now "building" his schematics. The integrated cross-referencing in QElectroTech automatically linked his Siemens contactors to their auxiliary blocks. The automatic wire numbering kept the complex I/O mapping organized.
By Friday, the project that should have taken two weeks was finished in four days. Elias exported the final PDF—a professional, industry-standard set of schematics that looked like they had been produced by a multi-thousand-dollar software suite.
When the lead technician arrived on Monday to start the wiring, he looked at the printed drawings and whistled. "New software, Elias? This looks like a pro-level Siemens job."
Elias smiled, glancing back at his screen where the QElectroTech logo sat alongside his free library. "Just the power of the community, Mike. Just the power of the community."
If you'd like to make this more technical or specific, let me know:
Which Siemens series should be the focus (e.g., LOGO!, S7-1500, or ET 200SP)?
Should the story focus more on the installation process of the library or the design phase?
QElectroTech (QET) is a powerful open-source tool for creating electrical diagrams, and while it includes a massive official collection of over 8,000 symbols, Siemens-specific libraries are often found through community contributions rather than a single "official" installer.
