The ongoing changes in manufacturing require that new information models for industrial computer systems be developed and applied. This paper describes a concept for the material model as a “digital twin” for producing highly customised, smart electronic devices. The scope of the research is the transformation of the models that are typical for the currently used automation pyramid approach to Reference Architecture Models for Industry 4.0 (RAMI4.0). The ISA95 standard is used as the modelling tool and Open Production Connectivity Unified Architecture (OPC UA) as the communication middleware. The presented use case focuses on a rework operation that is performed during the short series production of highly customised electronic devices that are produced by the Aiut company. The paper focuses on the transformation from the static architecture of Manufacturing Execution Systems to flexible and dynamic information models.
