2 Common Specifications of IAG Precautions for Correct Use • After IAGs execute a restore, some changes may be made in the settings of related devices, causing a communications failure between the NA-series Programmable Terminal and the NJ/NX-series CPU Units. In this case, the restore completion result from the IAGs cannot be acknowledged, and therefore the restore result is indicated as a failure. However, even though this occurs, the target NJ/NX-series CPU Units are successfully restored with the backup data. • You cannot use IAGs to restore NX-series Safety Control Units. You need to use the Safety Unit restore function for such restore.
For details, refer to relevant sections in the NX-series Safety Control Unit User’s Manual (Cat. No. Z930) . 2-6 Programmable Terminals NA-series Practices Guide NJ/NX/NA-series Backup and Restore IAG (V127)
