The TSN/A - Conference, a cooperation of the Avnu Alliance and the trade journals Computer & AUTOMATION and Elektronik automotive is now considered one of the knowledge hubs in the field of industrial Ethernet standards. Time Sensitive Networking (TSN) extends standard Ethernet to provide time sensitivity for applications that require robust, deterministic connectivity. TSN has broad impact, particularly in application areas such as industrial manufacturing, automotive, and pro AV / consumer IP networking. The 2019 TSN/A conference covered the technology aspects of standardization as well as application-specific topics in various markets and industries.
Fraunhofer and NXP jointly present TSN interoperability:
In the interoperability demo of the Lemgo researchers, the communication class "Isochronous cyclic communication with bounded low latency" is tested on the basis of "Scheduled Traffic" (maximum QoS - Quality of Service).
The test network is set up with components from different manufacturers (multi-vendor) and with link speeds of 100 MBit/s and 1 GBit/s (mixed link speed). The cooperation partners demonstrated how multiple protocols (PROFINET and OPC UA) can be transmitted over a TSN network without influencing each other (even in the highest QoS class mentioned). The basic TSN mechanisms used in the demonstration are Time Synchronization, Preemption and Time Aware Traffic Shaping. As further partners of the Centrum Industrial IT (CIIT), Phoenix Contact and Weidmüller are involved in the demonstration with their components. Co-developer and researcher at Fraunhofer IOSB-INA, Carsten Pieper, emphasized the importance of the participation of different domains and vendors: "Cross-company cooperation is an important basis for a successful development and market launch of industrial communication systems. Ethernet TSN is a very promising technology. However, sophisticated test and diagnostic concepts are important to master the complexity and interoperability."
