How is Time-Sensitive Networking (TSN) applied in industrial automation?

TSN for industrial automation: IEEE 802.1 standards providing deterministic Ethernet communication. Key features: time synchronization (802.1AS), scheduled traffic (802.1Qbv time-aware shaper), frame preemption (802.1Qbu), stream reservation (802.1Qcc), and redundancy (802.1CB). Applications: converged networks (control, safety, and IT on single infrastructure), motion control (sub-millisecond determinism), and OT/IT convergence. Implementation: TSN-capable switches and end devices, centralized network configuration (CNC/CUC), and traffic engineering. Benefits: reduced network infrastructure, guaranteed latency for critical traffic, and flexibility for mixed traffic types. Challenges: ecosystem maturity, interoperability testing, and migration from legacy protocols. TSN is foundation for Industry 4.0 communications.
