Import and export logic components Chapter 1
Configure component references
In addition to determining how the component is imported, you must configure
how references are imported. The references are all other components used by the
exported component at the time it was exported. For example, a program .l5x file
contains the definition of all controller-scoped tags, user-defined data types, user-
defined string types, and Add-On Instructions referenced by the program at the
time the program was exported. During import configuration, you determine what
the references from the imported component connect to after import. You can
connect a reference to an existing component in the project and not import the
referenced component from the import file. Or, you can use the referenced
component in the import file either by creating a new component in the project
from the definition in the import file or by overwriting an existing component of
the same type in the project.
As with imported components, if the Final Name of a referenced component
(such as a tag) matches a component of the same type and scope in the project,
these components collide. If there is no collision, the component is identified as
needing to be created (Operation is Create).
