OPC UA & MQTT FAQs
Why is OPC UA preferred over traditional protocols for connecting OT systems to IT applications?
OPC UA provides platform-independent, self-describing information models. Unlike older protocols that only transmit raw register numbers, OPC UA sends data bundled with metadata (units, data types, and status flags), accompanied by built-in cryptographic security and session management.
What advantage does Eclipse Sparkplug B provide over raw JSON payloads in MQTT?
Raw JSON requires receiver applications to guess or hardcode data structures. Sparkplug B defines a strict, standardized topic namespace and payload structure using Google Protocol Buffers, ensuring that all edge nodes report birth certificates, death certificates, and metric updates in a universally understood format.
