Hassle-free automation?
Checklist: 10 Steps to Digitize Your Plant
Avoid costly implementation errors
🚨 The Automation Pyramid Is Dead
If you are still integrating your plant by connecting PLC → SCADA → MES → ERP in a linear chain, you are building an architecture that was born obsolete. It's time to talk about your factory's neural network.
What is the Unified Namespace (UNS)? #
The Unified Namespace is not software you buy. It is an architecture. It is the idea that all components of your factory (sensors, machines, robots, software) should publish their data to a centralized location accessible in real-time.
Imagine a "Group Chat" (MQTT Broker) where each machine greets and says: "I am Injector #1, running at 180°C and just made a part". Any other system needing that info (ERP, Maintenance, Quality) simply "listens" to that chat.
🆚 The Battle of Architectures
❌ ISA-95 (Old School)
- • Hierarchical Structure (Pyramid)
- • Data trapped in silos
- • "Point-to-Point" Integration (Spaghetti)
- • Expensive and hard to scale
✅ UNS (The Future)
- • Hub & Spoke Structure
- • Single Source of Truth
- • Event-Driven (Real Time)
- • Plug & Play Scalability

The 4 Pillars of UNS #
- MQTT as Protocol: Lightweight, fast, and designed for unstable networks. It is the language of UNS.
- Sparkplug B: The "grammar" of MQTT. Defines HOW machines should speak to understand each other automatically.
- Edge Gateway (iGromi): The translator. Takes data from legacy PLCs (Modbus, Ethernet/IP) and converts to MQTT.
- The Broker: The central server (HiveMQ, Mosquitto, EMQX) that manages data traffic.
Why is iGromi ideal for UNS? #
Most traditional SCADAs (like WinCC or FactoryTalk) hate UNS because it breaks their "walled garden" business model. iGromi OS is UNS native.
When you install an iGromi node on a machine, it automatically:
- Reads local sensors.
- Standardizes data to Sparkplug B.
- Publishes to your central MQTT Broker.
Build Your UNS Today
You don't need to throw away your PLCs. You just need a smart "translator" at the edge.
