Hi Team,

Will the data flow in Cognite is Uni-directional or Bi-directional?

Thank you,

Navyasri,

Thank you for the clarification. The typical data flow path is, for example: OPC UA (source) → CDF. Once the data is in CDF, you analyze it there and/or create an application. Depending on the nature of the application, you could optionally send data you query from CDF back to the same or other OPC UA destination. An HMI is an example of an application where you could make CDF API calls to extract data. It would natively be able to write back to an OPC UA device.

Navyasri,

Can you provide examples of data sources, destinations, and data flow direction as a simplified use case? I think I know, but I do not want to assume what you mean.

To clarify further, do you mean data flow within a model, or between physical sources, through CDF, and back to the same or other physical things?

Hi Jon,

Thanks for replying to my question.

Yes, want to know about the data flow between physical sources to CDF and vice-versa will be possible (data flow is uni-directional or bi-directional) ?

Thank you,
