Azure Digital Twins Microsoft Learn - Learning Pathway
The goal of the new learn path is to take the learner on a journey of creating an end-to-end industry based solution using ADT. The hands-on exercises leverage a manufacturing scenario, where learners will be using the Chocolate Manufacturing Factory example to complete the practical units and accomplish e2e solution building.Microsoft Azure learning path for developers: Develop with Azure Digital Twins.
Digital Twin Definition for device with multiple ports
Hi there, I am attempting to write an IoT Central device template for a NetIO PowerPDU 4C power distribution unit. The device has four metered & switched power ports, and ships with Azure IoT Hub connectivity. I am attempting to use Azure IoT Central to track the power usage of each four ports individually over time. I am struggling to understand how to write a device template for a device with "many" outputs, as each power port has its own set of telemetry/properties that can be set individually, and it's unclear from the documentation if DTML or IoT Central can support this kind of device, or if the PDU would need to be set up as a "gateway" with each of the ports functioning as an individual device. The following is an example of a raw/unmodelled telemetry payload sent via MQTT from the PDU: { "_unmodeleddata": { "Outputs": [ { "ID": 1, "Name": "output_1", "State": 1, "Current": 38, "PowerFactor": 0.58, "Load": 5, "Energy": 3894 }, { "ID": 2, "Name": "output_2", "State": 1, "Current": 79, "PowerFactor": 0.57, "Load": 11, "Energy": 4343 } ] }, "_eventtype": "Telemetry", "_timestamp": "2022-03-13T22:31:52.62Z" } Is it possible to codify a "has-many" relationship such as the above in DTML, or is IoT Central not compatible with the device? Please let me know if you need further information!
Cannot provision instances in Digital Twins
Hi, I am trying to create a Digital Twins resource, yet I always get the error in the attached image ("Cannot provision more instances"). I have tried to run an example in all sites (West US, East US, etc...), and I always got the same error. I don't have any instance, as far as I know. I searched the internet to know how to solve this problem, but I couldn't find a similar one. Why I get this error, and how can I solve this problem?The Azure Digital Twins team needs your input!
Here is an opportunity to help our engineering team shape the Azure Digital Twins service. This time Anil Kumar (aanik), PM in the Digital Twins team is seeking for input on access control needs in the context of Digital Twins scenarios and applications. If you are planning to or are already working on a project involving Digital Twins, help us make sure we ship what you need, filling in the following survey.
