In order to cope with variable external influences, these systems need to become more flexible. One basic building block to achieve more flexible automation systems from the software perspective are modular real-time architectures which are realized as distributed real-time systems. The improved modularity and flexibility come at the price of greater complexity. In order to enable developers to design robust systems regarding real-time properties, a domain specific language is proposed, which allows reasoning and validation of modules and composed distributed real-time systems.}, address = {Cham}, author = {Walker, Moritz and Fischer, Marc and Neubauer, Michael and Lechler, Armin and Verl, Alexander}, booktitle = {Production at the Leading Edge of Technology}, editor = {Bauernhansl, Thomas and Verl, Alexander and Liewald, Mathias and M{\"o}hring, Hans-Christian}, isbn = {978-3-031-47394-4}, pages = {268--279}, publisher = {Springer Nature Switzerland}, title = {Towards a Domain Specific Language for the Development of Distributed Real-Time Systems}, url = {https://link.springer.com/chapter/10.1007/978-3-031-47394-4_27}, year = 2024 }

  @inproceedings{10540878, abstract = {Distributed real-time applications perform deterministic tasks across multiple connected compute platforms, referred to as endpoints. Deterministic behavior of the communication and the compute are prerequisites, but coordinating and managing both in a holistic way is a significant challenge. Converged real-time networks based on Time-Sensitive Networking (TSN) are considered the key enabler across industries for the required connectivity. To date, the potential of TSN cannot be exploited due to many sub-standards still being under development, gaps in the management and configuration functions, lack of best practices and unresolved integration with higher application layers and domain specific engineering. Previous work, focusing on a modular open source framework for the engineering and management of distributed real-time applications, identified a unified approach for TSN-based endpoints as a key gap. This paper presents a novel endpoint architecture to operate, engineer and manage distributed real-time applications by seamlessly integrating real-time networking and compute. The architecture provides interfaces to a central engineering, allows to integrate centralized as well as distributed network management and offers a unified data management. An abstraction layer for applications allows the efficient use and complements existing open source solutions.}, author = {Oechsle, Stefan and Frick, Florian and Walker, Moritz and Lechler, Armin and Verl, Alexander}, booktitle = {2024 IEEE 20th International Conference on Factory Communication Systems (WFCS)}, doi = {10.1109/WFCS60972.2024.10540878}, issn = {2835-8414}, month = {04}, pages = {41-48}, title = {Endpoint Architecture for Distributed Real-Time Applications Based on TSN}, url = {https://doi.org/10.1109/WFCS60972.2024.10540878}, year = 2024 }
