Analysis of the Round Trip Time of OPC UA and TSN based Peer-to-Peer Communication

At the SPS IPC Drives in Germany a joint working group between the leading automation manufacturers announced to work together on a set of vendor independent standards for the next generation of industrial communication products. This set of standards is based on OPC UA and Time Sensitive Networking (TSN) and shall be used throughout the automation pyramid. This work contributes to analyze the performance of OPC UA and TSN. Therefore, a test framework is implemented to measure the round trip time of a peer-to-peer communication. The round trip time is an important performance indicator for controller-to-controller and controller-to-field device use cases.
