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 IE Field Network master/local module and a bridge module
(NZ2AW1GFAL) 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.
Module
CC-Link IE Field Network master/local

Bridge module (NZ2AW1GFAL)
*1 Set the target station.
*2 Excluding when the error code is 0131H.
Considerations for data backup/restoration
■Stations to which data cannot be backed up and restored
The data backup and restoration function cannot be performed on the following stations.
• Local station
• Sub-master station that is monitoring the master station (performing the sub-master operation)
• Station whose data link has stopped due to a station number duplication error
• Station whose data link has stopped due to a station number out of range error
• Station whose network number is mismatched
■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.
■Operations with a display unit during data backup
If any of the following operations are performed with a display unit during data backup, the operation will be completed
abnormally and the error is displayed on the display unit.
Operation name
Project data batch save/load function
File deletion on the "Memory card operation menu" screen of a display unit
