Architecture of the Future

Flatten the Pyramid.
Build the Network.

The traditional automation pyramid is a bottleneck. Proxus UNS democratizes data, making every sensor, machine, and application a first-class citizen in your digital ecosystem.

The Old Way: The Bottleneck

Data must travel up through rigid layers (Sensor > PLC > SCADA > MES > ERP). Adding a sensor requires configuring 5 different systems, creating latency and cost.

ERP (L4)
MES (L3)
SCADA (L2)
PLC / Sensors (L1)

The Proxus Way: Unified Namespace

A central event-driven Data Broker where every system publishes and subscribes. Data is available to everyone, instantly. Single Source of Truth.

What is a Unified Namespace?

A Unified Namespace (UNS) is a single, well-structured topic hierarchy where all operational data lives: events, metrics, states, alarms. Instead of every system talking directly to every other system, each one:

  • Publishes what it knows to the UNS once
  • Subscribes to what it needs from the UNS when required

This eliminates point-to-point integrations, breaks data silos, and gives IT and OT teams a shared, real-time view of the factory. In Proxus, the UNS is not a slide in a presentation – it is the core runtime architecture.

From Spaghetti to Single Source of Truth

  • Publish once, consume everywhere
    Devices, SCADA, MES, ERP and analytics all connect to the same hub.
  • Security by design
    Edge Gateways initiate outbound connections; no inbound PLC ports.
  • Real-time, event-driven
    MQTT + NATS JetStream ensure low-latency streams with guaranteed delivery.

Structured Data, Not Chaos

Proxus enforces the ISA-95 standard hierarchy. This ensures that any application, AI model, or human knows exactly where to find data without asking the original integrator.

  • Self-aware Data Topics
  • Sparkplug B Payload Compression
  • Automatic Birth/Death Certificates

How Proxus Implements UNS

Proxus is built from the ground up around the UNS concept. Instead of bolting MQTT on top of a legacy platform, Proxus uses an actor-based architecture where every major component speaks the same language.

  • Edge Gateways
    Stateless Gateways collect data from PLCs and fieldbuses, normalise tags and publish them into the UNS. If connectivity drops, NATS JetStream buffers every event.
  • Central UNS Broker
    A highly-available MQTT broker becomes the Single Source of Truth for all plants, sites and applications.
  • Central Data Pipeline & Storage
    On the central server, the data pipeline consumes UNS streams and persists telemetry to PostgreSQL and ClickHouse without impacting the broker.
  • UNS Tree & Dashboards
    The UNS Tree Monitor and Blazor dashboards read from a high-performance in-memory cache, not directly from PLCs, ensuring real-time UI without extra load on the plant network.

All of this is configured from a single place: the Proxus central server. Gateways remain stateless and can be redeployed or replaced without losing their role in the UNS.

Why UNS with Proxus?

Whether you are modernizing a single line or rolling out across multiple plants, a Unified Namespace dramatically reduces integration cost and accelerates digital projects.

1. Real-Time Visibility

Operators, maintenance and management all see the same live data set: OEE, alarms, energy metrics and more – without building yet another custom dashboard per system.

2. Lower Integration Cost

New applications (MES, CMMS, AI platforms) subscribe to existing topics instead of requiring new point-to-point connectors. Projects move from months to weeks.

3. Future-Proof Data Model

A clean, ISA-95-aligned topic structure means AI, digital twins and analytics teams can explore data without constantly touching production systems.
