Abstrakt

The trend towards individual products and decreasing lot sizes demands more flexible production. One approach is skill-based engineering in which product properties are mapped to machine capabilities. The machine skills require uniform semantics, unique designations, and widespread communication standards. The integration of machines and their capabilities via OPC UA into the Cyber-Physical Production System is an already implemented approach. Until now, skills have been used for simple actions that do not require time consuming calculations or simulations in advance. The paper shows existing OPC UA skill models and extends them by a feasibility and context check. In the future these models will allow to ask a Cyber-Physical Production Module in advance if a skill can be executed with a defined parameter set. This results in an interface to the digital twin of the Cyber-Physical Production Module.
