A demonstrator with a 2-node network using embedded 4-core Intel Apollo Lake Linux systems with Intel I210 controllers was setup in order to demonstrate the real-time performance of OPC UA PubSub over TSN. Technical and configuration data of the main components of the demonstrator can be obtained through the standard OSADL QA Farm interfaces where they are integrated as virtual rack "d". For a larger image of the demonstrator click on the image on the right, for an even larger image click here, and for a very, very large image click here.
