22 CPU MODULE DATA BACKUP/RESTORATION
FUNCTION
This function backs up data such as program files, a parameter file, and device/label data
*1
of a CPU module to an SD
memory card. The data backed up in the SD memory card can be restored as required.
*1 Module access devices and buffer memory are excluded.
The following table lists the backup and restoration methods of the CPU module data backup/restoration function.
*2 When using the automatic restoration with the SD CARD OFF button, set it before the backup processing. After setting, execute each
backup processing. ( Page 319 Settings for automatic restoration with the SD CARD OFF button)
The restoration function modifies programs, parameters, or device/label data of the CPU module. After
restoration, check the restored data carefully before an actual operation. (Check the data with an engineering
tool.)
When using the CPU module data backup/restoration function, check the versions of the CPU module and
engineering tool used. ( Page 747 Added and Enhanced Functions)
