Industrial IoT & Edge

Industrial IoT architecture and edge computing: OPC UA and MQTT, unified namespace, gateways and protocol translation, digital twins, time-series data, industrial wireless, sensors, data acquisition and device lifecycle.

Where AiVibe comes in

AiAmbA IoT is AiVibe's edge protocol layer: it discovers devices and normalises industrial signals, with supported protocols including Siemens S7, Mitsubishi MC, Delta Modbus, OPC UA and MQTT, and driver availability confirmed per installation. Writes to machines are deny-by-default.
