Industrial IoT (IIoT) platforms connect physical machinery, sensors, and equipment to centralized software for real-time monitoring, data collection, and operational intelligence across the production floor. Core capabilities include sensor and device connectivity (OPC-UA, MQTT, Modbus), edge computing for local data processing, real-time equipment dashboards, predictive maintenance analytics, asset utilization and downtime tracking, digital thread traceability, and integration with SCADA, MES, and ERP systems. The category spans enterprise IIoT platforms (PTC ThingWorx, Siemens MindSphere, GE Vernova, Honeywell Forge) and focused industrial data platforms (Tulip, Sight Machine, MachineMetrics) that emphasize shop-floor connectivity and rapid deployment.
