The control of multi-component groups often requires real-time communication and a communication architecture that is adapted to the distributed control concept.We present applicable communication concepts for distributed interpolation, where the distributed interpolation use case in particular demonstrates challenges caused by the synchronous execution of skills.}, keywords = {distributed interpolation, deterministic real-time communication, time-Sensitive Networking, IEC 61499}, language = {english}, } @inproceedings{SchneiderMaMo2018, author = {Schneider, Ben and Voss, Sebastian and Wenger, Monika and Zoitl, Alois}, title = {Using IEC 61499 Models for Automatic Network Configuration of Distributed Automation Systems}, booktitle = {9th Vienna International Conference on Mathmatical Modelling (MATHMOD2018)}, year = {2018}, month = feb, timestamp = 2018.02.21, abstract = {The new Ethernet standard Time-Sensitive Networking is an enabler for Industrial Internet of Things (IIoT) but gets more and more difficult to configure with a continuous rising number of network nodes, because each node has to be set up separately.

We discuss this trend in the context of automotive and medical systems. The goal of this paper is to elaborate the research challenges of new platforms for such open systems. A main problem is that such CPS apps shall be able to access and modify safety critical device internals. We present results of the TAPPS (Trusted Apps for open CPS) project, which develops an end-to-end solution for development and deployment of trusted apps. The main approach is to devise different execution environments for highly-trusted CPS apps.

Recently, several approaches to include timing aspects have been suggested.However, these approaches focus predominantly on later development phases. Models specifyingthe requirements with respect to timing without focusing on a specific solution are missing.For example, few models allow the specification of the allowed jitter of a system.In this paper, we identify requirements that are necessary to express the desired timingbehavior of hard and soft real-time systems by analyzing different application domains.Based on these results, we evaluate existing approaches with respect to their suitabilityto model timing requirements and present an suitable approach.
