An asset administration shell (AAS), as a key concept of the Industry 4.0, provides a machine accessible interface to any kind of asset. An application implementing the devices functionality should be able to interact with different AASs. In this work, we specify the function blocks (FBs) for accessing properties and invoking operations of AASs. We analyzed the nature and requirements of such FBs while focusing on REST/HTTP- and OPC UA-based AASs and provided IEC 61499-based implementation. The expected outcome of this paper will ease an interaction with the complex AAS structure from the low-level devices.
