Creating a new "Digital Twin Template"

The Digital Twin Template allows you to connect the virtual simulation model to the onboarded asset in MindSphere. This mapping allows the link between the signal/parameter in the virtual model and the measurable variable from the aspect of the asset type. The mapping also saves the data type and units for the both virtual and physical models.

Digital Twin Template establishes the relationship between physical model and virtual models. The physical model is captured from Data Model in the Platform. The virtual model comes from different enterprise Applications.

The Digital Twin template and the instance can then be used to set up the configuration for a simulation run. Once the simulation is executed, the foundation provides services to establish the traceability between the simulation and the simulation result.

Creating a Digital Twin Template

To create and configure a new Digital Twin Template, proceed with the following steps:

  1. In "Closed Loop System Simulation", click "New Digital Twin Template" in the "Home" screen.

  2. In the "Details" page,

    • In the "Enterprise Application" field, choose the enterprise application from the dropdown

    • In the "Search for Model" field, click "Search" and select the Enterprise model definition file from the existing list. Based on the selected model, the Description, Selected Enterprise Model and Sampling Time fields are automatically populated

    • Enter the Name

    • Click "choose" to upload an icon for the Digital Twin Template

    • Click "Proceed to next step"

  3. In the "Desigin Constants" page, the details are displayed.

  4. In the "Variables and Thresholds" page, enter the Lower Limit, Upper Limt values for the variables. Select the "Use as KPI" checkbox if necessary. Click "Proceed to next step".

  5. In the "Mappings" page,

    • Click "Add a mapping"

    • Choose the Asset type from the dropdown

    • Choose a variable from the dropdown

    • Choose the virtual variable from the dropdown

    • Click "Add Mapping"
      The created mapping is displayed on the screen.
      To delete the mapping, click the "delete" icon next to the mapping in the "Mapping Overview" section.

    NOTE

    • The assets shared from other tenants(shared assets) are visible in the "Asset type" dropdown, and support the creation of Digital Twin Templates, Digital Twin Instances. It is also possible to run simulation on shared assets.

    • A physical variable can be mapped to a single virtual variable.

    • A virtual variable can be mapped to a single physical variable in a given Asset and Aspect.

    • Duplicate mappings are not allowed.

  6. Click "Save".
