OPC UA excels at structured industrial data models with strong typing and security. MQTT excels at lightweight pub/sub across sites, brokers, and cloud services.
Connected operations require both: OPC UA to speak with PLCs and MES systems, MQTT to fan out normalized events to analytics, dashboards, and digital twins.
Auvetra's integration layer maps OT semantics to governed topics, enforces access control, and preserves lineage so operations teams trust the data crossing IT boundaries. See our Connected Operations and Industrial Connectivity services for how we deliver this in production.
