Generate Digital Product Passports by Integrating Production Data into the Asset Administration Shell

The Digital Product Passport (DPP) is a data set that contains information about the product throughout all stages of its lifecycle. Recently, a wide variety of activities are being undertaken to introduce DPP to the industry. However, putting the DPP into practice is still challenging. In this paper, we propose a method to integrate production data acquired from existing manufacturing systems into elements within the DPP submodel, following the required structure of the AAS. We also validate the feasibility of the proposed method and provide a use case of DPP in a real-world environment. The proposed approach provides the benefit of easily creating and managing DPP without the need to modify existing systems. Additionally, it facilitates flexible updates to the information contained within the DPP.
