Backup when changing the parameters
If the CPU module parameters have been changed, turn the CPU module power OFF and ON or reset the CPU module to
apply the parameters. Then execute backup. If backup is executed before the parameter changes are applied, restoration
may not be carried out correctly.
Random folder/file
Do not create a random folder/file in the CPU data folder. The backup will not function correctly in the CPU module auto
exchange mode.
