Mapping an aspect to a data source

Data mapping means matching variables of an aspect with the respective data points of a data source.

  • Variables of an aspect represent the MindSphere data.

  • Data points of a data source represent the data of the MindConnect Element.

To use the data of your MindConnect Element you have to map them to the respective variables of an aspect.

Requirement

You have created an asset based on your desired aspect and asset type.

Procedure

To map a variable to a data point, e. g. "RotationSpeed", follow these steps:

  1. Click on the asset in the "Assets" tab, e. g. "Wind turbine1".

  2. Click on the MindConnect Element Plugin icon, e. g. "MindConnect Nano".

  3. Click "View data mapping".

  4. Select the aspect, e. g. "Generator".

  5. Select the variable you want to map to the data point, e. g. "RotationSpeed".

  6. Select the data point you want to map and click "Link Variable".
    The following graphic shows the "Link Variable" option:

  7. Select the previously created asset type and click "Accept", e. g. "Wind turbine".

    NOTE

    You can find additional information on asset types in the chapter Creating a type in Asset Manager.

    NOTE

    Only units and data types that match exactly with the aspects and variables are available. If they are different, the aspect can’t be connected to the data point (also case sensitive).

  9. To link the variable click "Accept".

Result

The data point is now mapped to the variable.
