OPC UA over TSN Technology Description

This document provides a technology description for implementing OPC UA (Unified Architecture) over TSN (Time-Sensitive Networking), focusing on Publisher/Subscriber (PubSub) communication and real-time extensions for industrial automation. It covers supported scenarios such as communication between B&R controllers and third-party devices, time synchronization via PTP, and key TSN mechanisms like IEEE 802.1Qbv, Qav, Qci, and Qcc for deterministic networking.
