Execution method of data restoration
The target device for data restoration can be set with a program.
■Acquiring a right to use
Set a value within the range from 1000H to 1FFFH to SD1435.
Right to use for data backup
• Special relays (SM) and special registers (SD) are used for data restoration.
• To prevent the same special relay (SM) and special register (SD) from being set at the same time, acquiring
a right to use of them for data backup is required.
• To acquire a right to use, specify a value which is not duplicate with values for other request sources to
SD1435, and check that the value set to SD1435 is stored to SD1436.
• Normal operation cannot be assured if the data backup function is performed without confirming the
acquisition of a right to use.
■Setting the restoration setting
1.
Setting a target module type
Set the target module type for data restoration to the lower 8 bits of SD1437.
Target module type
3H: Ethernet
2.
Setting an execution unit
Set the unit of execution for data restoration to the upper 8 bits of SD1437.
Execution unit
1H: Module unit
2H: IP address unit
3.
Selecting a folder for data restoration
Set the number for backup folder name, from which data is to be restored, to SD1438.
Target folder
00 to 99: Target folder specification
4.
Setting a target device
• Setting the module
When '1H' (module unit) is set for the execution unit in the step of 'Set the execution unit', set the built-in Ethernet port CPU as
the target device of data restoration to SD1439.
Target device (Module)
03FFH: Built-in Ethernet
• Setting IP addresses
When '2H' (IP address unit) is set for the execution unit in the step of 'Set the execution unit', set the IP addresses of target
devices for data restoration to SD1440 and SD1441.
Number Target device (IP address)
*1
SD1440 0 to 65536 (FFFFH): IP address (lower 16 bits)
*1
SD1441 0 to 57343 (DFFFH): IP address (upper 16 bits)
*1 IP addresses within the range from 0.0.0.1 to 223.255.255.254
6 Ethernet

6.5 Backing up/Restoring Data of Devices Supporting iQSS
Description
Set the target module type.
Description
Set this to specify all devices supporting iQSS which communicate with a restoration target module among the devices
supporting iQSS which are connected to a built-in Ethernet port CPU.
Set this to specify only the device supporting iQSS with the specified IP address among the devices supporting iQSS
which are connected to a built-in Ethernet port CPU.
Description
Specify the number among the numbers for backup folder name, 00 to 99.
Description
When '1H' (module unit) is set for the execution unit, set a built-in Ethernet port CPU connected to a target device
supporting iQSS.
Description
When '2H' (IP address unit) is set for the execution unit, set the IP address of a target
device supporting iQSS.
