15 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.
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 1008 Added and Enhanced Functions)
• This function cannot be used in the R00CPU, R01CPU, and R02CPU.
