Designing Your UNS Topic Hierarchy with ISA-95
The article discusses designing a Unified Namespace (UNS) topic hierarchy using ISA-95 and ISA-88 standards. It emphasizes that each segment describes a data location, not its type, ensuring predictability in topic paths. Five anti-patterns are identified, highlighting common pitfalls in topic structuring. The goal is a clear, consistent tree for efficient data flow in industrial… Read →

Why Point-to-Point Integration Fails at Scale
Point-to-point integration becomes problematic as the number of systems increases, leading to a combinatorial explosion of interfaces and heightened fragility at ISA-95 level boundaries. This method incurs significant costs, including ongoing support and operational risks, making it unsuitable for larger plants. A unified namespace presents a scalable alternative for integration.

What Is a Unified Namespace? A Ground-Up Definition
A unified namespace (UNS) is an event-driven architecture in which every system in a plant publishes its current state to one central broker, organized in a semantic hierarchy that mirrors the business. Any producer writes to it. Any consumer reads from it. Nothing integrates point-to-point. The result is a single, live source of truth: at… Read →
