Digital Twin – Modeling Interrelated Devices Figure 6 Advanced Modeling of the pump station digital twin The proposed model includes a digital twin representation that encapsulates the behavior of the physical components and their relationships. Typically this complex modeling requires proprietary cloud back end support beyond the basic IoT framework but we hope that in the near future cloud Platform as a Service (PaaS) infrastructure would support this natively. Next we take a look at existing plant floor standards that already have semantics of the things/devices and how they could be leveraged to expedite the creation of digital twin representation for a factory. P UTTING I T A LL T OGETHER For Smart Factory applications, data comes from Programmable Logic Controllers (PLCs), drives, historians, etc. Historically, data collection took place using a list of ‘atomic’ data points or tags.
