OriginalThe unified namespace, explained
One broker, one topic tree, every producer and consumer decoupled. What a UNS is, what it demands, and where it goes wrong.
Industrial IoT / IIoT
Industrial IoT platforms, devices, and architectures.
OriginalSparkplug B in one page
The topic namespace, birth certificates, and state awareness that turn MQTT from a transport into a plug-and-play OT data fabric.
From vibration sensor to work order: sensing, transport, context, models, and the analytics layer where predictions become decisions.
Three technologies that get compared as rivals but usually work as layers. What each one owns, and how to stop choosing between them.
Adapters, agents, and streams — how the open machine-tool connectivity standard works and where it fits beside OPC UA.
The three MQTT features that decide whether your telemetry is lossy, stale, or exactly-once — and when each setting is correct.
Protocol conversion, buffering, and context at the edge — the four gateway patterns that connect legacy equipment to modern platforms.
