Digital Twin – Modeling Interrelated Devices
M ODELING C OMPLEX D IGITAL T WIN R ELATIONSHIPS
Let’s work with a use case that illustrates how the digital twin plays a central role in an Industrial
IoT (IIoT) solution implementation. The figure below depicts a simplified representation of a
water pump station. We follow the same color scheme to indicate static, commands and reported
telemetry values.
Figure 1 Gen Set Digital Twin
Static property that seldom changes (i.e., height of the tank)
Dynamic property (i.e., tank level)
Command to device
From a device standpoint we distinguish at least two devices as part of the pump station:
Pump station device = Tank Device + Pump Device
