Situations When You Cannot Go Online with a Controller Possible Recovery
• More than 1000 controller edits were made.
• A download of another project copy with identical creation stamps occurred.
• Changes were made to the offline project, excluding documentation and tag
value changes.
• A controller nonvolatile storage load occurred and the loaded image has the
same creation stamp but a different download stamp.
• A controller nonvolatile storage load occurred and the loaded image has the
same creation and download stamps but the change log is dated earlier than
the project file.
• Full download to the controller
• Upload from the controller to a new project
• Upload from the controller and merge with
an existing project.
• The project was exported and then reimported. In this case, the software
considers it a different project and it has its own unique stamps.
• A different project, with different stamps, was downloaded.
• A controller nonvolatile storage load occurred, and the image was generated
from a completely different project file, with different stamps.
• Full download to the controller
• Upload from the controller to a new project.
An upload/merge of documentation is not
possible in these cases.
The .L5X import/export file consists of the components listed in the table. The
