I--- Qelectrotech Siemens Library - May 2026

The QElectroTech Siemens Library provides a specialized collection of over 8,200, mainly community-contributed, electrical symbols for PLC modules like the S7-1200 and LOGO! series to support detailed industrial documentation. Users can expand the default, read-only collection by downloading elements from the QElectroTech community forum or creating custom symbols using the built-in element editor, as discussed on the QElectroTech Forum QElectroTech QElectroTech: Welcome, presentation

Having a pre-built QElectroTech Siemens Library means you don't have to draw the logo, pin layouts, or connection points for standard hardware like the S7-1200 or ET 200 distributed I/O. Instead, you can simply drag and drop these elements onto your workspace, ensuring: i--- Qelectrotech Siemens Library -

and includes elements for PLCs, HMI panels, and other industrial automation modules. QElectroTech Key Features of the Siemens Library Standardized Construction Standardize Siemens symbol usage across electrical projects

  • Standardize Siemens symbol usage across electrical projects.
  • Speed up schematic design by providing ready-to-use, correctly scaled symbols.
  • Reduce errors by ensuring pin labeling and functional definitions match Siemens documentation.

QElectroTech (QET) is a free, open-source CAD/CAE software designed for creating professional electrical, hydraulic, and pneumatic diagrams. The Siemens Library in QET refers to a collection of pre-made symbols and component representations (elements) specifically modeled after Siemens industrial hardware, such as S7-1200 PLCs, contactors, and power supplies. 1.
