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: The sensor/actuator twinning control loop can involve automated devices (SensorDevice and/or ActuatorDevice) and or humans (SensorHuman and/or ActuatorHuman).

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)

An actuator is a device that is responsible for moving or controlling a mechanism or system. It is controlled by a signal from a control system or manual control. Source Wikipedia
A sensor is a transducer that receives and responds to a signal or stimulus from a physical system. It produces a signal, which represents information about the system Source Wikipedia
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.
