Qelectrotech Siemens Library Jun 2026

In the world of electrical engineering, schematic design software is often expensive, cluttered, and locked behind proprietary formats. Enter —a free, open-source solution for creating electrical diagrams, wiring plans, and control panel layouts.

The QElectroTech Siemens library is a specialized collection of symbols ( .elmt files) that conform to Siemens’ industrial component designs. While QET comes with a comprehensive base library, a Siemens-specific collection ensures that your schematics look professional, adhere to standards, and represent the actual hardware being installed. These libraries generally include symbols for:

Integrating Siemens Components into QElectroTech: A Complete Guide

Instead of drawing custom symbols for a SIMATIC S7-1200 CPU, you can drag and drop it from the library. qelectrotech siemens library

Start small. Build your top 10 Siemens components this week (a CPU, a contactor, a breaker). Within one month, you will have a reusable asset that pays back exponentially.

Default QET installations come with generic symbols (relays, fuses, motors). However, Siemens uses specific part numbers (MLFB), proprietary PLC addresses (I/Q/M memory), and specific graphical styles for their S7-1200, S7-1500, and LOGO! devices. Manually creating these 200+ symbols is tedious.

: Rather than creating unique elements for every amperage (e.g., 5A, 10A, 20A), create one generic element and use the Element Editor to change properties or labels as needed. Organization : Store custom Siemens symbols in your User Collection

Using accurate, manufacturer-specific symbols makes wiring diagrams easier for technicians to read on the shop floor.

To keep your Siemens library clean and functional, follow these "proper post" guidelines from the QET community: QElectroTech Grid Alignment While QET comes with a comprehensive base library,

The Siemens library in QElectroTech is a specialized subset of the larger QET elements collection , which contains over 8,000 symbols in its latest versions. It primarily includes:
