■Communication load
When data is backed up or restored, the load of the service processing in the CPU module is temporarily increased.
Consequently, a communication response will be slow and a timeout error may occur in other communications.
To avoid a timeout error, review the value set for "Device/Label Access Service Processing Setting".

■Data backup/restoration for CC-Link IE Field Network master station
• Data backup in station sub-ID unit: When a folder storing backup data of a station (the I/O numbers and station numbers
are the same) is specified and the data is backed up again, use a module of the same model as that of the CC-Link IE Field
Network master station which has been used for data backup.
• Data restoration: Use a module of the same model as that of the CC-Link IE Field Network master station which has been
used for data backup.
■Multiple CC-Link IE Field Network master stations are mounted on a single base unit
Do not perform data backup/restoration when multiple CC-Link IE Field Network master stations having an identical network
number are mounted on a base unit. Data cannot be backed up/restored properly.
■Change of backup folders/data
Do not change a backup folder name, configuration, or saved file.
Otherwise, the data may not be restored properly.
For the backup file capacity, refer to the following section.
