Websites like or The Noun Project have industrial icons, but you must filter for "SVG" and "attribution-free for commercial use." Never use a free icon found on Google Images inside a commercial HMI—license violations are costly.
A growing trend is , which moves away from overly complex 3D renderings. HPG symbols are simplified, abstract representations that prioritize operator effectiveness, reduce cognitive load, and convey state changes with minimal distraction.
: Using a unified library ensures that every screen in a facility follows the same visual language, which is essential for training and safety.
Inconsistent graphical components and varying tag naming conventions can negatively affect process reliability and plant safety. A well-structured image library eliminates ambiguity, ensuring that alarms, warnings, and critical status indicators are instantly recognized. hmi image library
More specialized platforms distinguish between (traditional SCADA symbols with multiple visual states for motors, pumps, valves, and tanks) and HPG Collections (High Performance Graphics designed to meet ISA-101 standards for effective operator interfaces).

Colors should support pattern recognition and highlight the most important information for the operator, not simply create a stylish display. A good practice is to use embedded trends for key parameters and reserve bright colors like red exclusively for alarm conditions. The ISA-101 standard advises using strong colors, blinking, or flashing except in special situations to alert operators to critical conditions. Websites like or The Noun Project have industrial
To actually roll out a new HMI image library across your facility, follow this 7-step checklist:
Modern HMI image libraries come in several forms, each serving different needs and development environments.
have become the gold standard for HMI libraries. Unlike traditional bitmaps, SVGs can be resized without losing quality. This flexibility allows engineers to build interfaces that look professional on everything from a 4-inch handheld device to a 60-inch control room monitor. Conclusion : Using a unified library ensures that every
AVEVA InTouch offers a powerful situational awareness graphics library that provides contextualized information to operators. A key feature is the ability to import externally created SVG graphics, whether saved as image files or converted to the AVEVA Industrial Graphics format.
An image that looks beautiful on a 27" 4K monitor might be un-tappable on a 7" resistive touchscreen. Ensure your "hit target" (touch area) is at least 1 cm².
