FA³ST Service

The Fraunhofer Advanced Asset Administration Shell Tools (FA³ST) Service enables creation of Digital Twins (DTs) in accordance to the Asset Administration Shell (AAS) specification . FA³ST Service is a software that, when started, offers one or more AAS-compliant APIs to interact with a DT. Optionally, it can be started given an existing AAS model file and/or a configuration file. FA³ST Service also allows synchronizing a DT with the asset(s) it represent via so-called AssetConnection.

FA³ST Service: Non-Technical View.

Implemented AAS Specifications

  • Details of the Asset Administration Shell - Part 1: Metamodel v3.0 (specification)

  • Details of the Asset Administration Shell - Part 2: Application Programming Interfaces v3.0.1 (specification) (OpenAPI)

Features

  • Easy to use even for non-developers via command-line interface (CLI), docker container, or embedded library

  • Configuration via a single JSON file

  • Open Architecture: easily extendable and configurable

  • Asset Synchronization: synchronize your assets and DTs using arbitrary communication protocols

  • Allows accessing your DT using multiple endpoints at the same time, e.g., HTTPS and OPC UA

  • Uses existing open source implementation of AAS datamodel and de-/serializers Eclipse AAS4J

  • Supports several dataformats for the Asset Administration Shell Environment: AASX, JSON, XML

Caution

At the moment there is no security specification available for the AAS. Therefore FA³ST does not implement any security mechanisms. They will be implemented as soon as a security specification is available. We strongly recommend to be careful when using external AAS models or submodels.
