Digitalization of the Components of a Mini Factory with the Implementation of RAMI 4.0 Asset Administration Shell

In the era of Industry 4.0, characterized by the paradigm shift towards Smart Manufacturing, the traditional hierarchical and rigid control system architectures and information silos are being redefined to realise a vision of dynamic system reconfiguration through the seamless integration of Operational Technology (OT) and Information Technology (IT) systems. This paper explores the implementation of the Asset Administration Shell (AAS), recognized as pivotal in integrating the vertical dimensions of the Reference Architecture Model for Industry 4.0 (RAMI 4.0). The study demonstrates the deployment of AAS across various hierarchical levels, showcasing the digitalization of diverse production facility assets and their standardized representation in a technology-neutral manner. A use-case is presented to illustrate the concept of dynamic process execution facilitated by Manufacturing Execution System (MES) and Manufacturing Operations Management (MOM), leveraging the capabilities offered by digitalized assets. The implementation adheres to current standards and companion specifications, underscoring its scalability for wider adoption across the industry.
