This demonstrator clearly shows the advantage of using Ethernet TSN and its capability to support multiprotocol, multivendor and multirate communication within a single network, offering an excellent platform for converged industrial networking.
The demonstrator showcases Ethernet TSN interoperability, using an isochronous cyclic communication pattern with bounded low latency. It is based on the LS1028ARBD reference design board from NXP, which is built around the QorIQ® Layerscape LS1028A industrial application processor, running Open Industrial Linux (OpenIL). The network implements TSN mechanisms according to the existing draft IEEE/IEC 60802 TSN IA standard (time synchronization, time-aware scheduling and frame preemption). Besides the four LS1028ARDB connected in a daisy-chain topology with the link speed of 1Gbps, the demonstrator includes some additional equipment from other vendors: Phoenix Contact provides PROFINET controller and devices, simulating RT field-level communication at 100Mbps. At the same time, the Weidmüller OPC UA Pub/Sub controller publishes isochronous packets, also at 100Mbps. Finally the communication is visualized on the oscilloscope screen, allowing any timing inconsistencies to be observed.
