MQTT Sparkplug B: The Standard for OT-to-Cloud Telemetry & Unified Namespace (UNS)

Why vanilla MQTT is not enough for industrial automation: how Sparkplug B provides explicit OT topic namespaces, state management (NBIRTH/NDEATH), Protobuf payloads, and auto-discovery.

  • Standard MQTT has no data structure rules; Sparkplug B defines an exact topic hierarchy and data modeling specification.
  • Sparkplug B introduces state management (NBIRTH/NDEATH) so subscribers know with certainty if an edge node is alive or dead.
  • Binary Protobuf encoding reduces telemetry payload sizes by up to 80% compared to verbose JSON strings.
