In this chapter of the three-part series in the magazine Fluid, it is explained how AAS, OPC UA, and AML can create interoperability together without competing with each other, and how to avoid problems such as double modeling or double development. The Administration Shell, AutomationML, and OPC UA together form a comprehensive digital interoperability solution for devices, software, and assets throughout their entire lifecycle. Recommendations are given to avoid proliferation and to utilize existing formats and information models instead of re-modeling them. It is recommended to use the AAS as a lifecycle document that enables unified access to data and facilitates interoperability throughout the lifecycle. This paper was developed to provide guidance and application recommendations for interoperability. It describes how the technologies AAS, AML, and OPC UA fit together and how interoperability can be achieved across domains. The authors provide specific application recommendations and emphasize that interoperability is not achieved through a single global model, but through a clever combination of different standards. The associations and organizations declare their willingness to collaborate in order to avoid double standardization. [Extracted from the article]

At the Hannover Messe 2023, various companies such as Siemens, Bausch+Ströbel, Bosch Rexroth, Cadenas, Festo, Harting, Sick, Phoenix Contact, and Wago were presented on how the administration shell can be implemented in practice. The administration shell is a manufacturer-independent and industry-neutral standard promoted by the Industrial Digital Twin Association (IDTA). Siemens supported this use case with the help of software solutions from the Siemens-Xcelerator portfolio. The partners jointly evaluated the added value of the administration shell based on a specific use case at Bausch+Ströbel. In addition, various organizations and associations have published a discussion paper on interoperability to provide guidance and recommendations for action. [Extracted from the article]
