Rockwell Automation 20D-DL2-CKS1 Import/Export Project Components - Manual (Page 18)

Chapter 1 Import and export logic components
collision or other situations, for example, project security privileges, may affect
what Operations are permitted for a component.
The following table describes the configuration options.
Configuration Description
Import Name The Import Name is read-only and shows the name of the component as read from the
import file.
Operation The Operation determines whether the component from the import file is imported. Not
all operations are applicable to a given component in all situations. Sometimes there is
only one possible operation permitted in a particular situation.
Choose from these options:
• Use Existing (collisions) to use the existing component in the project. The component
definition in the import file is not imported. If the component collides and there is no
definition for the component in the import file, then this is the only Operation
available.
• Overwrite (collisions) to import the component definition from the import file and
overwrite the existing component definition in the project.
Important: If you select Overwrite for a reference tag, the tag data that is different is
written to the offline project only, even if you are online with the controller.
• Create (non-collisions) to import the component from the import file creating a new
component in the project.
• Discard (non-collisions) to discard the component and abort import. If the main
component from the import file (the program during a program import, for example) is
discarded, the references can still be imported. If a referenced component is discarded,
any imported logic references are not defined in the project and might not verify after
import.
• Undefined (non-collision) is the only Operation available if the component does not
collide and there is no definition for the component in the import file. The imported
logic is not verified after import.
• Delete (non-collision) indicates that this component will be deleted from the project
on import.
Final Name The Final Name determines the name of the component that shows in the project after
the import (except in the case of a Delete Operation).
You can create or avoid collisions by changing the Final Name. If you change the Final
Name to differ from the Import Name, all logic references in the import content are
updated.
If you change the Final Name of a component during configuration so that it collides with a
different existing component after it was colliding with another, any changes you made to
the Operation are preserved.
Description The Description shown depends on the Operation. If the Operation is:
• Overwrite or Create, the description is initially the description from the import file.
You can edit it during import configuration.
• Discard, the description is initially the description from the import file. It is read-only
and may not be edited.
• Use Existing or Delete, the description is the existing component description. It is
read-only and may not be edited.
• Undefined, no description is shown.
The description for members of an expanded tag follow the same rule the tag follows. Only
members of the tag that have descriptions are shown when the tag is expanded.
