3.11.2 Backup and Restore User Program
Backup with Saia PG5
®
Select a backup with
“Copy program to flash...”
Since the user program is already stored in the on-board flash memory, only
the RAM DB/text data from the on-board flash memory is backed up in the folder
PLC_SYS. This folder is not visible for the user. Access is not permitted.
Registers, flags, timer and counters are not saved in this manner.
During a restore, the text/DB data is copied back into the SRAM memory.
Backup to the INTFLASH file system
In order to be able to
use backup/restore with
internal flash, a PCD_
BACKUP folder must
be created.
RAM DB/text data is
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.
