Backing up and restoring the user program
Backup with PG5
Select a backup with "Backup To Flash”
Since the user program is already stored in the on-board flash memory, only the
RAM DB/text for the on-board flash memory are stored to the folder PLC_SYS (not
visible to the user).
Note: Registers, flags, timers and counters are not stored.
During a restore, the DB/text are copied back into the SRAM memory.
Backup to INTFLASH file system
The values RAM DB/text are stored in the internal PCD_Backup folder. This allows
the backup files to be accessed via the FTP server and then uploaded to a PC.
