Include a Contained Type in an Object Type

Before you begin

Create an object type that you want to use as a contained type.

About this task

A contained type is an object type that you can include in another object type. When you do so, you can reuse the variables in the contained type without creating them again manually. These variables are inherited by object instances of the object type in which you include the contained type.

You can include a single contained type in multiple object types and multiple contained types in a single object type.

For more information, refer to About a Historian Model.
