5.3.4.3 Display Unit
[Mode] - Backup Internal Device
Copies data stored in the internal device addresses user area to
the backup memory (SRAM). If you specified the Backup Internal
Device, the display unit will retain data stored in the internal
device address when powering off the display unit.
Data stored in the internal device is
cleared when turning OFF the display unit or when the display unit
goes offline. You can use this function to back up the data in the
user area.
Backup
Set whether or not to backup the display unit internal
device.
Backs up the data stored in sequential
addresses in the user area. Select the user area range from LS area
or USR area. (System area or USR area for the memory link method.)
You cannot back up multiple ranges. If you select the LS area in
the direct access method, only one of the two user areas (red frame
portion) is backed up. This holds true for selecting the system
area in the memory link method.
Backup Start Address
Set the start address of the internal device to back up. Set the
start address so you can ensure the range of [Consecutive
Addresses].
For direct access method, the start address should be specified
within the range of LS20 to LS2031, LS2096 to LS8999, or USR0 to
USR29999.
For memory link method, the start address should be specified
within the range of 20 to 2031, 2096 to 8999, or USR0 to
USR29999.
Consecutive Addresses
Set the internal device size to back up.
If the [Backup Start Address] + [Consecutive
Addresses] exceeds the valid range of the internal device backup,
the backup function will not work.
If LS area or Memory Link's system area is
used, set from 1 to 6096. If USR area is used, set from 1 to
30,000.
Depending on the backup data capacity, screen
display updates may become slower.
