Points to be checked before data backup/restoration
■Check the availability of data backup/restoration
The data can be backed up and restored when a CC-Link master/local module and a bridge module (NZ2AW1C2AL) satisfy
the following conditions.
Perform the automatic address detection function and the parameter batch read function before data backup/restoration.
The 'n' indicates the address assigned to the master station by the station number setting.

*1 Set the target station.
*2 Excluding when the error code is 0131H.
■The "Read Model Name of Slave Station" checkbox on the "Operation Setting" screen
Check that "Read Model Name of Slave Station" is selected on the "Operation Setting" screen before performing the data
backup/restoration function. If it is not selected, the data backup/restoration function cannot be performed.
For details on the "Read Model Name of Slave Station" checkbox on the "Operation Setting" screen, refer to the following
section.

■Interlock setting
Some or all remote registers of a target device are used in the system during a data backup/restoration.
Therefore, add "Remote register use prohibited status (SW0160 to SW0163)" to the interlock when creating a program.
■The station whose operating status is switched from the standby master station to master
station
The data backup/restoration function cannot be performed to a station in which the operation was switched from the standby
master operation to the master operation.
In that case, turn the power OFF, and ON again in the order from the standby master station to the master station. Then,
perform a data backup/restoration.
Considerations for data backup/restoration
■Use of an SD memory card
• During a data backup or restoration, do not perform the following actions: turning OFF the power, resetting a module, and
inserting or removing an SD memory card.
Otherwise, the data backup or restoration will be interrupted and the data will not be backed up or restored properly.
• Normal backup data cannot be created if the memory size or the number of files exceeds the maximum storage capacity of
an SD memory card during a data backup.
