QElectroTech + Siemens Library — Making Industrial Schematics Smarter

When you’re designing electrical schematics for industrial automation, clarity and reuse matter. QElectroTech is a lightweight, open-source diagram editor built for electrical, electronic and automation schematics. Pairing it with a curated Siemens-style library (symbols, function blocks, device templates) brings professional polish, speeds design, and reduces errors. Here’s an engaging, practical blog post you can publish.

: Ensure terminal numbers (e.g., L+, M, I0.0) match the official Siemens Technical Documentation qelectrotech siemens library

Where to find community libraries:

• GitHub & GitLab: Search for "QElectroTech Siemens" or "qet_siemens". Many users share their .qet element files.
• QElectroTech Official Forum (https://qelectrotech.org/forum/): This is the primary hub. Look for threads tagged [Bibliothèque] or [Library] with titles mentioning Siemens, Simatic, or Sinamics.
• The Element Repository (qelectrotech.org/elements/): The official collection. Filter by "Manufacturer" – while limited, you will find basic Siemens contactors and circuit breakers (e.g., Siemens Sirius series).

Modular Design: Symbols often follow standard sizing to allow for easy alignment in cabinet layouts. GitHub & GitLab: Search for "QElectroTech Siemens" or

• Slanted contacts for NO/NC elements (different from IEC standard symbols).
• Integrated terminals (e.g., 3RV motor starters with built-in auxiliary switches).
• PLC I/O cards with unique addressing (Q, I, M, DB).
• HMI templates (KTP panels) with proprietary connection logic.

Integrated Collection: Check the "Common Collection" tab in your QET panel. Look under Automation > PLC > Siemens. Modular Design : Symbols often follow standard sizing

Part 1: What is QElectroTech? (A Quick Primer)

Before diving into the Siemens library, let's establish a baseline. QElectroTech is a Qt-based application used to design electrical control circuits, wiring diagrams, and fluid power schematics.
