Future production systems demand for a standardized digital representation of I4.0 components including their capabilities. Many concepts of such a digital representation have been published under the term administration shell. However, these concepts do not explicitly cover the use of administration shells to orchestrate real-time capable I4.0 components. In this paper, we recap an existing I4.0 framework that enables the dynamic orchestration of non-real-time I4.0 components. As main contribution, we integrate real-time capable I4.0 components into this framework. Thereby, the entire communication is standard-compliant to the new real-time technology Time-Sensitive Networking (IEEE 802.1). The advantages of our approach are demonstrated by a dynamic plug-and-produce scenario in which real-time axes are controlled based on G-code.
