Download/Upload a Safety Application Program
Upon download, application testing is required unless a safety signature exists.
IMPORTANT:
To verify that the correct safety application is downloaded or restored from a memory card, you must manually check that the safety signature matches the original signature in your safety documentation.
Downloads to a safety-locked controller are allowed only if the safety signature and the firmware revision of the offline project all match what is contained in the target controller and the safety task status of the controller is OK.
IMPORTANT:
If the safety signature does not match and the controller is safety-locked, you must unlock the controller to download. In this case, downloading to the controller deletes the safety signature. As a result, you must revalidate the application.
IMPORTANT:
To avoid project download failure, do not change the communication adapter name of a chassis containing safety I/O while the safety application has a safety signature.
If the controller contains a safety signature, the safety signature is uploaded in an online save of the project. The option to upload tag values includes both standard and safety tag values.
