The definition of UNS still remains arguable. From an automation perspective, UNS is a common naming convention that organizes devices, data points, and services based on their attributes, such as location, function, and type. But according to Walker Reynolds, UNS is not only a naming convention but an architecture that meets five requirements: UNS is the semantic hierarchy structure of business data and events. UNS is the hub that connects all smart devices and IT infrastructure. UNS is the single source of truth for all data and information in business. UNS is the foundation of future digital transformation. UNS is where the current state of business lives, enabling real-time snapshots of business.
