A Unified Namespace (UNS) is a structured, centralized data architecture that enables seamless integration and communication between various industrial systems, providing real-time, contextualized data in a scalable and organized manner. This session will explore how AVEVA PI System, a leading industrial data historian, can be connected to Manufacturing Execution Systems (MES) via a UNS, ensuring streamlined and optimized data flow. The UNS acts as a digital backbone, serving as a single source of truth across the enterprise. It enables AVEVA PI System to publish operational data—such as equipment performance metrics, process variables, and historical trends—in real time. By making this data accessible to MES systems, organizations can enhance decision-making, production tracking, and process optimization.
