Data Extraction and Storage Unit (DESU)

AmbiPower’s DESU (Data Extraction and Storage Unit) is the middle-layer of IoT stack that connects the on-field devices to the IoT Software Platform. The DESU shall collect data from field devices via a large variety of communication buses at regular intervals and push the data to a SCADA cloud server over a LAN or a Cellular connectivity platform.
