Industrial IoT (IIoT) integrates OPC UA (standard protocol), MQTT (lightweight pub/sub), IO-Link (smart sensing), 5G/LoRa/NB-IoT (wireless), edge computing (real-time local processing) and cloud platforms. Siemens MindSphere, PTC ThingWorx, AWS IoT, Microsoft Azure IoT and Bosch IoT Suite are mainstream platforms; use cases include predictive maintenance, energy management, remote monitoring and digital twin.

FAQ
Q OPC UA advantages?
A
Open, cross-platform, built-in security (X.509 certificates, encryption), information modeling (device + industry semantics), native PubSub (no broker needed). Industry 4.0 and ISO/IEC 62541 standard.
Q Edge vs cloud?
A
Edge (PLC + industrial PC): real-time (< 10 ms), available offline, low bandwidth. Cloud: bulk historical analysis, cross-plant benchmarking, AI training. Hybrid (edge pre-processing + cloud analytics) is mainstream.
Q IIoT security?
A
IEC 62443 OT security standard; network segmentation (OT/IT separation), zero-trust (verify every access), encrypted communication (TLS/MQTTS), device identity (X.509). Siemens and Phoenix Contact offer mature solutions.
