Webel Twin Pattern: An ActualPhysicalAsset is an asset that is also a «physical» PhysicalEntity.

Webel Twin Pattern: A DigitalTwin and PhysicalEntity must both be 'attached' to Sensors and/or Actuators under management of the DigitalTwin before the twinning control loop is fully entered.

Webel Twin Pattern: Not every twinnable PhysicalEntity is worth treating as an asset.

'Origins of the Digital Twin Concept', August 2016, Dr Michael Grieves

Webel Twin Pattern: A DigitalTwin (even a "process twin" or "finance twin"), always, without exception, BY DEFINITION HERE either directly or indirectly involves at least one existing or anticipated PhysicalEntity (even if only via another DigitalTwin)!

Today this process can occur in reverse, with the digital model developed first followed by the physical asset.

Traditionally, industry has created digital twins by retrospectively mapping, scanning, surveying, digitising or developing a digital copy of a real world object.

Webel Twin Pattern: A DigitalEntity (a.k.a. «digital» @Entity) used as a digital variant must not be directly bound to a «physical» PhysicalEntity (may not directly actuate/sense/affect)

Webel Twin Pattern: Communication between the ControlSystem of a DigitalTwin and its digitalEntity:@Entity is via a dedicated protocol (ReadTwin, WriteTwin) distinct from the sensor reading or actuator driving signals.

In contrast to traditional digital models, digital twins can connect with the physical ‘twin’ they model, changing alongside the physical system via real-time sensors and actuators.
