CPU module data backup/restoration function

The following is the list of special register areas relating to the CPU module data backup/restoration function.
No. Name
SD1350 Number of
uncompleted folders/
files of CPU module
data backup/
restoration
SD1351 Progression status of
CPU module data
backup/restoration
SD1353 Upper limit value
setting for the number
of CPU module
backup data
*1 When program files are restored, the progress in SD1351 stops while data is being written (transferred) 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.
*2 The CPU module where this function can be used supports these special register areas.

Appendix 5 List of Special Register Areas
Data stored Details
Number of This register indicates the number of folders/files where the
uncompleted folders/ backup/restoration of the CPU module is not completed. When the
files of CPU module backup/restoration processing is started, the total number of folders
data backup/ and files to be backed up or restored is stored. The number is
restoration reduced one each time one folder/file is backed up or restored, and
0 is stored when all the data is backed up or restored.
Progression status of • This register indicates the progression status of the backup or
CPU module data restoration in percentage.
backup/restoration Range of the value: 0 to 100 (%)
• "0" is set at the start of the CPU module data backup.
Setting of the upper Set the upper limit value for the number of the backup data for the
limit value for the CPU module data backup. (1 to 100)

Data stored Details
Right-to-use request Set the request number (desired 4-digit number) to acquire/release
number for data the right to use. Use the request number as follows depending on
backup/restoration the request source.
0000H: Right-to-use release request
1000H to 1FFFH: Request from the program
Right-to-use This register stores the request number of when the right to use for
acquisition number the iQ Sensor Solution data backup/ restoration has been acquired.
