Schema Generator

The Schema Generator is called at the completion of every process of creating a data type. In addition, it is possible to start directly with the Schema Generator if Start from scratch is selected.

1. Data Type Explorer: The Data Type Explorer displays the structure of the data type in a tree view.
2. Name: Name of the data type.
3. Title: Title of the data type.
4. Description: Description of the data type.
5. Base Type: Base data type of the data type.
• Scheme Type: JSON base data types.
• Existing Type: Arbitrary TwinCAT HMI data type.
• Multiple: Arbitrary data types with restrictions: AnyOf, AllOf or OneOf (see JSON documentation).
• Not Set: Do not set a data type. This necessitates a manual restriction of the data type.
6. Define Subtypes: Enables the definition of subtypes within the schema. A subtype is a user-specific data type within the user-specific data type.
7. Additional Properties: Adds optional properties to the data type. Optional properties enable the addition of further properties that are not required, but are validated (see JSON documentation).
8. Required Properties: Defines all properties that are required. One property is entered per row. The data type is not valid if it is lacking a required property.
9. Subschema Preview: Provides a preview of the generated schema of the selected node in the Data Type Explorer.
