2 Common Specifications of IAG 2-1 Function NJ/NX/NA-series Backup and Restore IAGs (hereinafter, "IAGs" unless otherwise noted) function on a NA-series Programmable Terminal as software components to back up, restore and compare data of Controllers and the NA-series Programmable Terminal. Additional Information • To back up, restore or compare the data of a NJ/NX-series CPU Unit, IAGs use the SD Mem- ory Card backup function of the CPU Unit. And therefore, the scope of those operations with IAGs depends on the SD Memory Card backup function capability. For details on the SD Memory Card backup function, refer to the NJ/NX-series CPU Unit Software User’s Manual (Cat. No. W501) .
• For a backup of an NX-series Safety Control Unit, IAGs back up the Safety Unit restore file in the SD Memory Card in the connected NX-series CPU Unit. Therefore, you need to store the Safety Unit restore file in the SD Memory Card in advance. Refer to the NX-series Safety Control Unit User’s Manual (Cat. No. Z930) for details. 2-1-1 Backup You can use IAGs to back up programs and settings of NJ/NX-series CPU Units, as well as those of the NA-series Programmable Terminal. You can also back up the Safety Unit restore file in the SD Memory Card in the NX-series CPU Unit or NX-series Communication Control Unit, either of which is connected to an NX-series Safety Control Unit.
In addition, you can specify a save-in location of the backup data and how to start a backup using the IAG. You can select a backup start method from any of the following: • Manually execute a backup by using the BackupToUSBMemory or BackupToFTPServer button • Use ConfigureBackup to perform scheduled backup on a regular basis Additional Information The scheduled backup can be executed when the storage location for the backup result is set to an FTP server. You can select a storage location for the backup result from the following two locations:
• USB flash drive inserted to the NA-series Programmable Terminal • FTP server accessible by the NA-series Programmable Terminal Additional Information If you select an FTP server as the storage location, you can configure the backup settings to save only device data that has been changed since the last backup. 2-2 Programmable Terminals NA-series Practices Guide NJ/NX/NA-series Backup and Restore IAG (V127) Selecting a Backup Start Method Selecting Storage Location for Backup Result
