Tier 2 – Edge Gateway and cloud connectivity 

Sensor data from various sensors, such as temperature or pressure sensors, starts as analog data and then gets converted into digital streams. It is then aggregated and sent downstream to systems for in-depth processing. Data Acquisition Systems (DAS) typically do these conversation and aggregation functions on-board the Edge Gateways. The DAS connects to the sensor network using various industrial protocols such as ModBus and OPCUA, aggregates data, converts the data from analog into digital streams and then forwards it to data processing systems. The Edge Gateway receives the data from the DAS and then, using a cloud connector, sends the data to Tier 3 cloud systems for further processing.
