The QET Elements Forum is a hub where users share specific Siemens .elmt files they have created. 💡 Best Practices for Use

For Siemens SIRIUS contactors, place the primary coil element on your control circuit page. Link it to its corresponding auxiliary contacts (NO/NC) placed on power or signaling pages using QET’s built-in Element Linker . This automatically tracks cross-references.

, an open-source marvel, but his latest project—a massive automated assembly line—required the precision of components qelectrotech siemens library

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.

Efficient electrical schematic design requires both powerful open-source software and reliable component data. QElectroTech (QET) provides the open-source platform, but manually drawing complex automation components like Programmable Logic Controllers (PLCs), variable frequency drives, and digital I/O modules slows down engineering workflows.

Navigate to your downloaded and extracted Siemens library folder and select the files.

For power users maintaining a large QElectroTech Siemens library, manual creation is too slow. The (a separate Python utility) allows you to: Link it to its corresponding auxiliary contacts (NO/NC)

For the latest additions (like S7-1200 or S7-1500 modules), users often pull directly from the Official Elements GitHub .

All elements follow a consistent grid for clean, professional schematics.

QElectroTech (QET) is a popular open-source software for creating electrical diagrams, and its Siemens-specific library is a vital resource for engineers working with Simatic PLCs, Sinamics drives, and other industrial automation hardware.
