Saving Files from CX-Integrator to SD Memory Card
You can restore the data setup file into a DeviceNet Unit by saving a device parameter file (extension .dvf)
for this DeviceNet Unit created with CX-Integrator to an SD Memory Card with the file name DNnn-
BKUP.dvf (nn: unit number (2-digit hexadecimal), mounting it in the CPU Unit, and changing the software
switch *_Sw2FileRestoreCmd (Unit Setup File Restore Switch) to TRUE.
Note The file name when saving setup data to the SD Memory Card must be DNnnBKUP.dvf (where
nn is the Unit number in 2-digit hexadecimal). For example, for unit number 00, the file name
must be DN00BKUP.dvf. If the file is saved under another name, the data cannot be restored
from the SD Memory Card to the DeviceNet Unit.
