Digital Twin is a key enabling technology of Industry 4.0, Smart Manufacturing and Made in China 2025, and a broad literature emerged. But existing literature tends to focus on large-scale equipment or large products, often in a fixed position layout. This study argues that this is due to the use of centralized data and system models. It proposes new architectures for digital twins based on local product and resource twins that use digital encapsulated information to create higher level system twins. Using Action Design Research, a first tentative to develop a prototype of this new architecture is presented. A main learning outcome is that the Programmable Logic Controller (PLC) is an essential part of a digital twin implementation, which receives insufficient research attention. The capability of the PLC largely determines the architecture of a digital twin.
