OPC UA PubSub over TSN: Deterministic Fieldbus Replacement for Multi-Vendor Robotics

The future of vendor-agnostic real-time deterministic communication: combining OPC UA Publish/Subscribe (Part 14) with IEEE Time-Sensitive Networking (TSN) for sub-millisecond control.

  • Traditional OPC UA uses TCP request-response client-server architecture, which has variable network latency.
  • OPC UA PubSub broadcasts UDP multicast or raw Layer 2 Ethernet frames with guaranteed deterministic delivery.
  • Combined with TSN switches, OPC UA PubSub achieves sub-millisecond cycle times with jitter below 1 microsecond.
