*1 Only 1 (CPU module auto exchange mode (delete existing data)) is valid with firmware version earlier than "1.050".
*2 This operation is required when the firmware version is "1.050" and later.
If the backup processing is completed with an error and SM953 (Data backup error check flag) turns on, check SD953
(Backup error cause), take actions, and then back up the data again as required.
The execution status of the backup processing can be checked with SD1350 (Number of uncompleted
folders/files of CPU module data backup/restoration) and SD1351 (Progression status of CPU module data
backup/restoration). (Page 168 Progress of the backup/restoration processing)
Checking backup errors
When an error has occurred, a diagnostic error is not detected and an error code is stored in SD953 (Backup error cause).
(Page 401 List of error codes)
Precautions
The following describes the precautions for the backup function.
Prohibited operation during execution of the backup processing
Do not perform the following operations during execution of the backup processing.
• Attaching or detaching the SD memory card
• Powering off or resetting the CPU module
The above mentioned operations leave the backup data in the SD memory card in an incomplete state which is in the middle
of the backup processing. Do not use these data for a restoration. If these data are used, the restoration completes with an
error.
