I4AAS – Industrie 4.0 Asset Administration Shell


The joint ZVEI, VDMA and OPC Foundation “I4AAS OPC UA” Working Group will develop an OPC UA Information Model for the Industrie 4.0 Asset Administration Shell (I4AAS).

Under the moderation of the OPC Foundation, the concept of the I4AAS, defined in a technology independent manner so far, should be transferred into the technology of OPC UA. The conceptual input of the I4AAS is a result of the Plattform Industrie 4.0 Working Group 1 “Norms, Standards and Reference Architecture”, the ZVEI Mirror Group “SG Standards and Models” and the ZVEI sub working group “Administration shell in detail”. To ensure the interoperability of the I4AAS with the OPC UA Companion Specifications (developed with the VDMA), the VDMA is included in addition (beside the ZVEI) as a member of the joint working group.

The OPC Foundation aspires to define the Industrie 4.0 Asset Administration Shell (I4AAS) technically as “OPC UA companion specification I4AAS”. Right now, on their own, many (7 are known) groups are currently working on prototypically implementations of the I4AAS based on OPC UA. This joint working group I4AAS should harmonize all these activities, but also coordinate with other stakeholders (like the VDMA) to synchronize the I4AAS with e. g. the initiative “VDMA Mechanical Engineering CS Type A” – which specifies the basic properties and functionalities in the mechanical engineering industry.


The implicit and explicit information model for the AAS should be specified conceptually by the ZVEI “SG Models & Standards” and aligned with the bottom-up Companion Specifications development with the VDMA. The I4AAS information model will be defined in OPC UA notation, using OPC UA constructs for the purpose of exposing I4AAS information to OPC UA applications and to exchange asset information between Industrie 4.0 components.
