Overview - Peer-to-peer - Star topology - Demonstrator (TSN) - Heterogeneous peer-to-peer - Demonstrator (OPC UA PubSub over TSN)
A demonstrator with a 4-node switched network using embedded 4-core Intel Bay Trail Linux systems with Intel I210 controllers was setup in order to demonstrate the various use cases and system configurations of OPC UA PubSub over TSN. Technical and performance 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".
