A digital twin is a digital representation of a physical asset, process or system kept in sync with reality through live operating data. It shows the current state, supports analysis of past behaviour and allows what-if simulation without touching the physical installation.
What a digital twin is
Unlike a static 3D model, a digital twin is live: it is continuously fed by the data the real asset generates and mirrors its present situation. What defines the twin is not visual realism but synchronisation with the real asset. The foundation is OT/IT data capture through an industrial IoT layer; on top of it come three staged uses: state visualisation, historical analysis and what-if simulation.
For an SME the right question is which decision the twin should support: testing production sequences, sizing an expansion, training operators. The common failure is the showcase twin: an impressive 3D replica that feeds no decision. See the industrial digital twin solution.
Frequently asked questions
- What is the difference between a digital twin and a simulation?
- A simulation runs with inputs defined by its user and can exist disconnected from reality. A digital twin is synchronised with the physical asset through live operating data and mirrors its present state. A twin may include simulation, but simulation alone is not a twin.
- Is a 3D model required for a digital twin?
- No. The essential part is the data model synchronised with the asset: variables, states and plant structure. 3D rendering is an optional visualisation layer; a useful twin can be a well-built data hierarchy without any 3D graphics.
- What does an SME use a digital twin for?
- The clearest returns are bounded: testing production sequences without stopping the line, evaluating an expansion or process change before investing, and giving state visibility over critical assets. Start from a concrete decision the twin must support.
- What is needed before building a digital twin?
- Reliable live data from the asset: connectivity with plant PLCs and sensors, a common structure for those variables and enough history. Without that OT/IT integration base, the twin is a mock-up disconnected from reality.
