Practical Steps Integrating HMI and SCADA into a Unified Namespace

This white paper outlines the integration of Human Machine Interface (HMI) and Supervisory Control and Data Acquisition (SCADA) systems into a Unified Namespace (UNS) architecture. It begins by explaining the necessity for businesses to access operational data sets that vary across departments, emphasizing the importance of tailored data structures for accurate analysis and efficiency. The paper details how HMI and SCADA systems facilitate data collection and integration, adhering to open standards such as ISA-95 and IEC 62264 to bridge operational technology and information technology. The document further discusses the challenges of traditional point-to-point data integration and the resulting data fragmentation, which complicates data accessibility. It presents UNS as a solution that enhances transparency and democratizes information across enterprise systems. The paper concludes by addressing the scalability and flexibility of HMI and SCADA architectures, which adapt to new technologies and standards, thus supporting future digital transformation efforts.
