After opening the azure digital twin data simulator, In the simulator type dropdown, only 2 demo models are available, how can I add new models.

Question

Answer 1

Hello Mudavath,

The Azure Digital Twins Explorer is a tool with multiple features:

1. Modelling the twin graph of your ADT envrionment
2. Access to the 3D Scenes studio to visualize your twins
3. ADT Data Simulator
4. A demonstration based on International Space Station data

You are looking at the data simulator.

Tes, there are two kinds of simulatons.

Here I run the robot arm simulation, next to a model I created myself:

In the graph explorer, it looks like this:

As you can see, both new models and twins are preset. The twins are even updated with new property values.

As you can see, I can add a new twin:

This twin will not be updates ofcourse, no logic is executed behind it.

This robotarm demo is also available as ADT tutorial.

You can also add the other demo, a dairy factory:

The models are uploaded too.

This one is also documented so you can try out the creation yourself.

Now, you are able to check out the demos and dive into the logic behind it.

Thank you @Sander van de Velde for your inputs on this.

@Mudavath Sairaj , in addition to the two out of the box simulation types available, here is a GitHub repository Manufacturing Ontologies that explains the creation and usage of new ontologies. The repository focuses on two of these ontologies, namely ISA95 to describe a factory ontology and IEC 63278 Asset Administration Shell to describe a manufacturing supply chain. Furthermore, it includes a factory simulation and an end-to-end solution architecture for you to try out the ontologies, leveraging IEC 62541 OPC UA and the Microsoft Azure Cloud.

If you scroll down to "Installation of Production Line Simulation and Cloud Services" you will see a full deployment of the architecture and a set of simulated factories.

Hope this answers your question. Please let us know if you still need any clarification or have any further questions on this.

Hello Mudavath Sairaj

We are checking on the thread!

To add new models to the Azure Digital Twins Data Simulator, you need to follow these steps:

1. Create a new digital twin model using the Azure Digital Twins API or Azure Digital Twins Explorer.
2. Export the model as a Digital Twins Definition Language (DTDL) file.
3. Import the DTDL file into the Azure Digital Twins Data Simulator by selecting "Import Models" from the "Models" menu.
4. Select the DTDL file from your local file system and click "Import."
5. After the import process completes, the new model should be available in the simulator's "Type" dropdown.

Note that the Azure Digital Twins Data Simulator supports only a subset of the Azure Digital Twins API's functionality and may not be suitable for all use cases. If you require a more feature-rich environment for testing your digital twins models, you may want to consider using the full Azure Digital Twins service instead.
