Communication for the Internet of Things

Easy synchronization of POWERLINK and OPC UA over TSN

At the 2019 Hannover Messe trade fair, the EPSG will be showing how easy it is to synchronize POWERLINK and OPC UA over TSN. Visitors to Booth D33 in Hall 9 will see first-hand how drives in five separate POWERLINK networks run in absolute synchronization. Their network clocks are synchronized via a shared OPC UA over TSN network.
The live demo at the EPSG booth comprises five independent POWERLINK networks with controllers and drives from various vendors. Not only is each POWERLINK network tightly synchronized internally, but interaction between them is also perfectly orchestrated. This is made possible by controllers that are enabled for both POWERLINK and OPC UA over TSN communication.

TSN switches from different vendors
The TSN network is set up using switches from Cisco, TTTech, Kontron, Moxa and Hirschmann Belden. Also connected to the TSN network are an HD camera providing a live stream, as well as OPC UA over TSN bus controllers from B&R to visualize the highly-precise synchronization using connected LEDs.
The demo shows how easy OPC UA over TSN makes it to join multiple existing machine networks into a single real-time network. OPC UA over TSN makes it easy to set up controller to controller communication at the line level. Together, open standards POWERLINK and OPC UA over TSN satisfy all the requirements of Industrial IoT solutions.
