Screen
Use screens to group objects that comprise a specific interface.
Screen types and instances
For optimal project maintainability, create screen object types and then use them with panel loaders or navigation panels. This allows you to modify all screen instances by editing the parent screen type.
Screens folder
Rockwell Automation recommends creating screen types in the folder in Project view. You can also create screen types in different nodes of your project, for example in the UI folder.
Each new project contains an empty Screens folder.
