ADT

[rploeg]

Hi,

I see in the documentation that you leverage Azure Digital Twins. In the sample code I can 'only' find:
Simulator --> IoT Hub --> ADX. Is that correct? Is there no 'integration' sample with ADT?

I have found the DTDL models that I can import in ADT, but don't see the flow yet between the other items.

thanks!

There is a built-in extension in ADX to query ADT, see here for two sample queries:
https://github.com/digitaltwinconsortium/ManufacturingDTDLOntologies/blob/main/ADXQueries/GetStationsForLineMunich.kql
https://github.com/digitaltwinconsortium/ManufacturingDTDLOntologies/blob/main/ADXQueries/GetUACloudLibraryURLs.kql

so the flow goes: Simulator --> IoT Hub --> ADX <-- ADT

Thanks, I saw that. But normally you 'store' the latest datapoints also in ADT (to create for example 3D maps). In this solution ADT is 'only' used as ontology if I am correct?

Thanks for the great work!

That's correct. For industrial workloads, you get much better perf sending data from IoT Hub directly to ADX and then querying the ADT graph via ADX, just like this reference implementation does.

Thanks for explaining the choices!
