6.5 Backing up/Restoring Data of Devices Supporting iQSS
Execution method of data backup
The target device for data backup 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 backup.
• 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 backup setting
1.
Setting a target module type
Set the target module type for data backup to the lower 8 bits of SD1437.
2.
Setting an execution unit
Set the unit of execution for data backup to the upper 8 bits of SD1437.
3.
Setting a number for a data backup folder name
Set the number for a backup folder name to SD1438.
Target module type
Description
3H: Ethernet
Set the target module type.
Execution unit
Description
1H: Module unit
Set this to specify all devices supporting iQSS which communicate with a backup target module among the devices
supporting iQSS which are connected to a built-in Ethernet port CPU.
2H: IP address unit
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.
Target folder
Description
FFFFH: Automatic specification
(Default)
Use the smallest number for a new backup folder name among the unused numbers as the backup folder name.
An error occurs when unused number is no longer available due to such cases as the number of folders reached the
upper limit.
FFFEH: Automatic specification
(folder deletion supported)
Use the smallest number for a new backup folder name among the unused numbers as the backup folder name.
The oldest folder is deleted and the number of the deleted folder is used for a new backup folder name when unused
number is no longer available due to such cases as the number of folders reached the upper limit.
00 to 99: Target folder specification
Set the number for a backup folder name.
When another folder with the same number exists, the operation will be as follows:
■
For module unit
• The backup folder with the same number is deleted, and a new backup folder is created.
■
For IP address unit
• Data in the backup folder with the same number is overwritten.
