The DM area, HR area, AR area, and counter values are backed up. If the
backup battery or capacitor is discharged, the contents of these areas will be
lost and the data values will revert to the defaults.
2. The contents of the program area, read-only DM area (DM6144 to DM6599),
and PLC Setup (DM 6600 to DM 6655) are stored in flash memory. The con-
tents of these areas will be read from flash memory the next time the power
is turned ON, even if the backup battery or capacitor is discharged.
When data has been changed in any of these areas, write the new values to
flash memory by switching the 3G3MV-P10CDT to MONITOR or RUN mode,
or by turning the power OFF and then ON again.
3. Changes made while in MONITOR mode using, for example, online editing,
are written to flash memory in real-time.
