: Provides a free library of graphic objects divided by category (motors, pumps, pipes, tanks, etc.) . These are designed for use in WinForm, WPF, or web-based HMI applications .
Siemens frequently releases free "HMI Template Suite" packages. These include optimized layouts, icons, and navigation elements designed around modern UI guidelines.
: Offers free Add-On Instructions (AOIs) paired with corresponding faceplates and graphic displays for FactoryTalk View. Key Formats: SVG vs. PNG in Industrial UI
The built-in symbols libraries and associated communities (like OpenClipart) feature extensive collections of industrial symbols, including pipes, valves, motors, and instruments compliant with ISA/ANSI standards. 3. Native Free Packages in Modern SCADA Platforms
For unique, non-industrial-specific icons, general vector sites are excellent.
Some free SVGs contain excess metadata from graphic software. Open them in a free editor like Inkscape, clean up the layers, and save them as "Optimized SVG." Import to SCADA:
: Offers resizable SVGs for high-resolution displays and static PNG equivalents for legacy systems.
If you tell me which SCADA software you are using (e.g., , AdvancedHMI , Opto22 ), I can recommend the exact library format that works best for you. Alternatively,
Most major automation software providers offer free, downloadable graphics packages to supplement their base software.
For more general interface elements, these platforms provide thousands of royalty-free options:
If you need modern UI elements rather than specific industrial hardware, these sites offer high-quality HMI-compatible graphics: Hmi Vector Art, Icons, and Graphics for Free Download
Modern HMI design leans toward minimalist flat icons rather than realistic 3D renderings. General web design repositories are incredibly useful for modern High-Performance HMI styles.
Inkscape is a free, open-source vector graphics editor widely used by automation engineers.
The Ignition Exchange is a free, community-driven marketplace. Developers share templates, custom SVGs, and entire HMI project screens. While optimized for Ignition, the underlying graphic assets and SVGs can often be exported and repurposed.
