*1 For module labels, data may be overwritten to the write areas from a module to the CPU module when the refresh settings have been
made.
*2 Device data may be overwritten depending on the mounting status (I/O refresh) of each module or the refresh settings.
Progress of the backup/restoration processing
The progress of the backup/restoration processing can be checked in SD1350 (Number of uncompleted folders/files of CPU
module data backup/restoration) or SD1351 (Progression status of CPU module data backup/restoration). However, the
progress of the automatic restoration cannot be checked with the special register.
*1 When program files are restored, the progress in SD1351 stops while data is being written to the program memory in the restoration
processing because the data is transferred from the program cache memory to the program memory. The progress of data transfer to
the program memory can be checked in SD629 (Program memory write (transfer) status).
