Human-Machine Interface (HMI) applications in manufacturing, energy, and building automation rely heavily on visual symbols (motors, pipes, tanks, valves, alarms). Currently, engineers often create, purchase, or import disparate image assets, leading to inconsistency, poor scalability, and increased development time. This paper proposes a – a structured, searchable, multi-format repository of standardized, resolution-independent graphical assets specifically designed for industrial HMIs. The library supports role-based access, version control, and export to common HMI environments (Siemens WinCC, Rockwell FactoryTalk, Ignition, CODESYS).

An HMI image library (sometimes called a picture or symbol library) is a curated collection of digital assets—such as icons, realistic renderings, and animated symbols—used to build graphical user interfaces for industrial control systems. These libraries typically include: Types of HMI Image Libraries Standard Software Libraries

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.
