4. If the project file exists, select it.
If the project to controller match is enabled, the Logix Designer
application checks whether the serial number of the open project and the
serial number of the controller match.
If the controller serial numbers do not match, you can do one of the
following:
• Cancel the upload and connect to a matching controller. Then, start the
upload procedure again.
• Select a new project to upload into or select another project by
choosing Select File.
• Update the project serial number to match the controller by checking
the Update Project Serial Number checkbox and choosing Upload.
5. The Logix Designer application checks whether the open project matches
the controller project.
a. If the projects do not match, you must select a matching file or cancel
the upload process.
b. If the projects match, the software checks for changes in the offline
(open) project.
6. The Logix Designer application 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.
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.
