6. The software checks for changes in the offline project.
a. If there are no changes in the offline project, you can go online without
uploading. Click Go Online.
b. If there are changes in the open project that are not present in the
controller, you can choose to upload the project, cancel the upload, or
select another file.
If you choose Upload, the standard and safety applications are uploaded. If
a safety task signature exists, it is also uploaded. The safety-lock status of
the project reflects the original status of the online (controller) project.

The software checks for the following:
• Do the offline project and controller serial numbers match (if Project to
Controller Match is selected)?
• Does the offline project contain changes that are not in the controller
project?
• Do the revisions of the offline project and controller firmware match?
• Are either the offline project or the controller safety-locked?
• Do the offline project and the controller have compatible safety task
signatures?
TIP Prior to the upload, if an offline safety task signature exists, or the offline
project is safety-locked but the controller is safety-unlocked or has no safety
task signature, the offline safety task signature and safety-locked state are
replaced by the online values (safety-unlocked with no safety task signature).
If you do not want to make these changes permanent, do not save the offline
project following the upload.
