Fraunhofer technology from Lemgo at the CES in Las Vegas

TSN research results from OWL go around the world

The Consumer Electronics Show (CES) is considered the largest trade show for innovations in the consumer technology markets. The trade show in Las Vegas in the USA has been a testing ground for highly innovative technologies for 50 years and presents them on a stage with global attention. Fraunhofer IOSB-INA holds up the flag for the technology region as one of the leading research institutions in the top cluster it's OWL and provided its know-how for a demonstrator of the business partner NXP. The presentation of research activities in an international context is not new for the Lemgo team - however, the presence at the CES illustrates how far-reaching the effects of innovations from East Westphalia-Lippe already are today: The Ethernet TSN technology on display offers a new level of performance in industrial communication that makes Industry 4.0 possible in the first place.

An Ethernet TSN technology exhibit from Fraunhofer IOSB-INA in Lemgo will be presented at CES from January 7 to 10, 2020. With the exhibit, Fraunhofer partner NXP Semiconductor shows the new level of possibilities and interoperability in industrial communication, which is achieved by TSN technology. 

Fraunhofer project manager Carsten Pieper is pleased about the international visibility of the technology from OWL: "Ethernet TSN enables continuous, scalable and flexible communication from the field level to the Internet, in which different protocols can be used simultaneously."

The TSN technology exhibit shows the communication class "Isochronous cyclic communication with bounded low latency" based on "Scheduled Traffic" (maximum QoS - Quality of Service). Components from different vendors (multi-vendor) and with link speeds of 100 MBit/s and 1 GBit/s (mixed link speed) are networked. It is shown how several protocols (PROFINET and OPC UA) can be transmitted over a TSN network without influencing each other (even in the mentioned highest QoS class). The basic TSN mechanisms used are time synchronization, preemption and time aware traffic shaping.

Fraunhofer scientist Mario Schoppmeier reports from his project experience: "Interoperability has always been a key success criterion for industrial communication systems. The introduction of Industry 4.0 and the high level of networking it requires increases the importance and the challenge even further."
