Asset Administration Shell
ECLASS in the Asset Administration Shell
Structures and properties at the click of a mouse as the basis for a digital twin
In an application developed by ECLASS members Festo, Phoenix Contact and SICK, users can create a digital representation of their product with just a few clicks.
Particularly noteworthy: Adding any number of properties is conveniently done with the click of a mouse. With the ECLASS classes as a basis, describing a comprehensive and structured digital twin can be done in the blink of an eye.
The Asset Administration Shell is the exchange format for the standardized exchange of IoT data in the Industrie 4.0 platform.
ECLASS members Festo, Phoenix Contact and SICK will provide a first-ever demonstration with the AASX Package Explorer of how this data exchange is implemented with an interface for ECLASS data (also via web service) that enables properties and entire structures to be imported and clearly interpreted.
With the AASX Package Explorer, users can create an exportable file that contains all of a product’s information in a structured and semantically defined form that is easily user-readable and thus contributes significantly to interoperability between product data users.
The AASX Package Explorer is available free of charge via GitHub.
AASX Package Explorer
Importing ECLASS data from a static XML file or through the ECLASS web service
Start the application
Begin import
Import from static XML file
Import via the ECLASS web service
Selection of structural elements: Search and filter for elements or classes (application class, block, aspect)
Import submodels
Internal class structure is being imported
Derived and linked concept descriptions

The figure illustrates two ways to import data via the AASX Package Explorer.
ECLASS is working in cooperation and close coordination with the platform Industrie 4.0 on a soon-to-be published model mapping.
A Webservice certificate can be requested from the Head Office for testing and research purposes related to the AAS.
WHITE PAPER OF PLATTFORM INDUSTRIE 4.0 AND ECLASS „MODELLING THE SEMANTICS OF DATA OF AN ASSET ADMINISTRATION SHELL WITH ELEMENTS OF ECLASS”
Plattform Industrie 4.0 recommends ECLASS as the preferred dictionary of standardized semantic to create meaningful Asset Administration Shells or Digital Twins. The AAS has standardized the structure and ECLASS has standardized the semantics for information elements, which should be used for the definition of digital twins. The structure of the AAS and the ECLASS dictionary complement each other in a perfect manner to achieve this objective.
The objective of this whitepaper is to work out which structures of ECLASS can be used to define the semantics of structures of the AAS. This whitepaper therefore explores element by element how each element of the AAS can be semantically described within the means of the ECLASS Conceptual Data Model.
ECLASS-WHITEPAPER ”DISTRIBUTED LEDGER-BASED INFRASTRUCTURE FOR INDUSTRIAL DIGITAL TWINS”
To master digitalization of industry the comprehensive availability of information is a key requirement. This is why concepts like the asset administration shell (AAS) and digital twins (DT) have been created.
Within this Whitepaper an approach is introduced to realize a decentralized registry for services offered around I4.0 components. How this decentralized registry is applied in practice is explained using five practice-relevant use cases which span the whole lifecycle of the asset.
