Considerations for Upload from a Safety Controller

For a safety project, the
Studio 5000 Logix Designer®
 application compares the following information in the project and the controller:
  • Controller serial number (if project to controller match is selected)
  • Open project to the controller project
  • Firmware major and minor revisions
  • Safety signature (if one exists)
IMPORTANT:
An upload is allowed regardless of the Safety status and the safety-locked state of the offline project and controller. The locked status follows the state of the uploaded project.
Upload Behavior
Response
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.
  • Connect to the correct controller or verify that this is the correct controller.
  • Select a new project to upload into or select another project by choosing Select File.
  • If it is the correct controller, select the Update project serial number checkbox to allow the download to proceed. The project serial number is modified to match the controller serial number.
The Logix Designer application checks whether the open project matches the controller project.
  • If the projects do not match, you must select a matching file or cancel the upload process.
  • If the projects match, the software checks for changes in the offline (open) project.
The Logix Designer application checks for changes in the offline project.
  • If there are no changes in the offline project, you can go online without uploading. Click Go Online.
  • 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.
Uploading safety signature...
This message appears during the upload only if a safety signature matching the one in the controller does not exist in the offline project.
If you choose Upload, the standard and safety applications are uploaded. If a safety signature exists, it is also uploaded. The safety-lock status of the project reflects the original status of the online (controller) project.
TIP:
Before the upload, if an offline safety signature exists, or the offline project is safety-locked but the controller is safety-unlocked or has no safety signature, the offline safety signature and safety-locked state are replaced by the online values (safety-unlocked with no safety signature). If you do not want to make these changes permanent, do not save the offline project following the upload.
