Edge to Cloud Data Flow

The following diagram depicts the data flow from an industrial asset to Edge and onto Cloud Data Services.

Edge to Cloud Data Flow

The data flows from edge to cloud as follows:

  1. Telemetry data from the asset is retrieved or received from the asset. Depending on the protocol, the data could be broadcast or the protocol adapter would request the data from the asset.
  2. The Protocol Translator transforms data to be sent to Time Series and publishes to the Databus.
  3. The Cloud Gateway subscribes to data from the Protocol Adapter and sends it to Digital-hosted Cloud Applications and Services.
    1. A custom app can also subscribe to data from the Protocol Translator for post-processing.
    2. Data from the Protocol Translator can also be stored locally in Historian.
  4. A custom application can publish data back to the Databus after processing for cloud or local ingestion.
  5. Finally, the Cloud Gateway publishes data to Digital-hosted Cloud Applications and Services. Data is held in a store & forward buffer to handle intermittent connectivity.
