What is a digital twin? Why every twin starts with data
A digital twin is a live virtual model of a physical asset, process or place. It is only as good as the data that keeps it in sync with reality.
What is a digital twin?
A digital twin combines three things: a model of something real (a machine, a building, a city district, a supply chain), a continuous stream of data from that thing, and the logic to analyse, simulate and predict. Unlike a static 3D model or a dashboard, a twin changes as its real counterpart changes.
Types of digital twins
- Asset twin: a single machine, pump or turbine.
- System twin: a production line, a substation or a hospital ward.
- Process twin: how work, energy or materials flow through an operation.
- Place twin: a building, a campus, a port or an entire city.
Why every digital twin starts with data
Most twin projects spend more time integrating data than building the model. Real assets are monitored by PLCs, SCADA systems, historians, IoT sensors and business systems, each with its own protocol and format.
If that data arrives late, incomplete or in inconsistent units, the twin drifts away from reality, and the simulations and predictions built on it lose their value.
What a twin needs from its data layer
- Coverage: connectors for every relevant source, from field devices to ERP.
- Consistency: one data model, common units and synchronised timestamps.
- Continuity: buffering and resending when connections drop.
- Control: data that stays where your security policy requires.
Common digital twin use cases
- Predictive maintenance in manufacturing.
- Energy optimisation in buildings and grids.
- Flood and emergency planning in cities.
- Patient flow and capacity in hospitals.
- Supply chain simulation in logistics.
How ALLINLET fits in
ALLINLET is the data layer for digital twins. It collects data from 900+ sources across 22 domains, normalises it and delivers one continuous stream to ALLFLOW's Digital Twin and AI simulation platforms, or to any twin you already use.
Frequently asked questions
Is a digital twin the same as a simulation?
No. A simulation models what could happen. A digital twin is connected to live data, so it mirrors what is happening now, and can then run simulations from that real starting point.
How long does it take to build a digital twin?
It depends on the scope. Starting with one asset or one process, and connecting its data first, is usually the fastest route to value.
ALLINLET connects to IoT sensors and industrial systems through 900+ connectors across 22 domains, and delivers one clean data stream, in our cloud or in your own infrastructure.
