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.
