A Unified Namespace (UNS) is a central real-time data architecture where all production and enterprise data is published into a single structured MQTT-based data space. Instead of point-to-point integrations, all OT and IT systems publish and consume from one shared namespace.
It becomes the operational “single source of truth” for connected manufacturing.
Real-time visibility across plants, lines and machines
Reduced integration complexity through publish/subscribe architecture
Cleaner OT/IT convergence with a shared data model
Stronger analytics for OEE, quality and energy
1. Cross-plant OEE reporting
Standardized machine events feed a central dashboard with comparable KPIs.
2. Process & quality analytics
Process parameters and QC data share the same namespace → faster root-cause analysis.
3. Digital transformation alignment
UNS acts as the reference model for all new OT/IT projects.
Treating UNS as a product instead of an architectural pattern
Missing contextual data (orders, quality states)
No governed topic model
Seeing MES only as a consumer instead of a data provider
A Cloud MES leverages the UNS by:
Consuming machine and process data
Publishing context (orders, shifts, quality states)
Calculating KPIs
Enabling scalable integrations without custom connectors
