IIoT gateways enable data routing beyond network boundaries. They establish secure connections of data sources and systems in the field via the Industrial Internet of Things (IIoT).
This allows for communication between separate process levels.
Their key tasks are to collect, pre-process, buffer and transfer sensor data to make them available for other networks and systems,
both horizontally within the Operational Technology (OT) layer and vertically for the connection to cloud platforms and IIoT systems.
