Note that the Safety Unit Restore function restores only the target data in NX-SL5£££ Units. To re-
store the entire system, you need to execute this function together with the SD Memory Card backup
function.
Precautions for Correct Use
• To execute the Safety Unit Restore, you need to execute the restore function for the NX102
CPU Unit as well. In addition, you need to generate a safety backup file and a backup file of
the NX102 CPU Unit from a same project or from a same project of a same physical unit
where a project was transferred from. If the settings for the safety backup file and that for the
backup file of the NX102 CPU Unit are not consistent, the safety control unit does not operate
normally.
•
Before executing the Safety Unit Restore, make sure to confirm the safety of the transfer des-
tination.
• Before executing the Safety Unit Restore, verify that the operation target is correct.
• Before executing the Safety Unit Restore, verify that the signature displayed on the seven-
segment indicator of the Safety CPU Unit is correct.
• To prevent accessing a wrong Safety Unit Restore File, make sure to control the file access
and configuration properly.
• After executing the Safety Unit Restore, verify that the Unit is configured correctly and the
Unit behaves as intended.
• To prevent executing the Safety Unit Restore by unauthorized person, make sure to keep un-
der access control to SD Memory Cards and Safety Unit Restore Files.
