By sending a start command through SDO communications, backup is executed during IO-Link com-
munications if the following conditions are met.
• The port settings for the IO-Link Master Unit are as follows.
Port£ IO-Link Device Configuration Data/Pin4 Com-
munications Mode Setting
Port£ Device Verification Setting
Port£ Backup/Restore Setting
• The Parameter upload start service data is supported by the IO-Link device.

Refer to 9-14-5 Executing a Start Command for Backup through SDO Communications on page 9-38
for information on how to execute a start command.
Additional Information
Backup will fail if you attempt it for an IO-Link device that does not support the backup func-
tions. A Warning-level Device Event Flag occurs at that time.
Automatic Backup after Clearing Backup Data in the IO-Link Master
Unit
By clearing the backup data, the settings of the IO-Link device after change are backed up. This meth-
od is used in the following cases.
• When the settings of IO-Link devices are changed with the CX-ConfiguratorFDT or through SDO
communications.
• When the settings of the IO-Link devices are changed through SDO communications and a backup
is performed for one IO-Link master at a time, e.g., when changing over a production line.
If the following condition is met, when you clears the backup data, the IO-Link Master Unit executes a
backup.
• The port settings for the IO-Link Master Unit are as follows.
Port£ IO-Link Device Configuration Data/Pin4 Com-
munications Mode Setting
Port£ Device Verification Setting
Port£ Backup/Restore Setting
For information on how to clear backup data, refer to 9-14-6 Clearing Backup Data on page 9-38.
Precautions for Correct Use
