A Reference Model for Common Understanding of Capabilities and Skills in Manufacturing

In manufacturing, many use cases of Industry 4.0 require vendor-neutral and machine-readable information models to describe, implement and execute resource functions. Such models have been researched under the terms capabilities and skills. Standardization of such models is required, but currently not available. This paper presents a reference model developed jointly by members of various organizations in a working group of the Plattform Industrie 4.0. This model covers definitions of most important aspects of capabilities and skills. It can be seen as a basis for further standardization efforts

Automation of an industrial OPC UA FX use case through the usage of proactive Asset Administration Shells

Automation of an industrial OPC UA FX use case through the usage of proactive Asset Administration Shells Katharina Justmann1, Ludwig Leurs2, Jesko Hermann3, Martin Ruskowski4 Abstract: Flexible and order-driven production are essential concepts for smart factories that effectively carry out lot-size-one production. These concepts depend on manufacturer-independent information exchange throughout the production lifecycle. While Open Platform Communication Unified Architecture Field eXchange (OPC UA FX) enables standardized communication between shop floor controllers, its configuration requires additional effort. To achieve flexible communication in changing production environments the configuration needs to be automated. The Asset Administration Shell (AAS) and the associated bidding process offer a potential solution to achieve this automation. The concept of a combination of the AAS and OPC UA FX was already formulated [DWR22a]. In this paper this concept is extended with activities of the Capability, Skill, and Service model to automate the configuration and production planning process of an OPC UA FX demonstrator. This paper shows that the information models and concepts are complementary yet lack generic mappings between the defined structures and semantics
