Industrial Internet of Things (IIoT) systems enable the connectivity of numerous devices, which are heterogeneous in terms of their interfaces and supported protocols, into one system to derive more intelligent actions from data. Digital Twins are a key enabler for IIoT systems, which allow the acquisition, access, and exchange of far greater variety of data than today and previously unseen interoperability out of the box. This paper elaborates on the definitions of digital twins, their role in IIoT systems and the necessary architectural decisions that software/system architects have to make to design digital twins.
