Restoring Settings

After you replace an IO-Link device with the same model of IO-Link device, you can transfer (i.e., re-
store) the parameter settings (called backup data) that are backed up in the IO-Link Master Unit to the
replacement IO-Link device from the IO-Link Master Unit.
Restoration is executed automatically when IO-Link communications start if the following two condi-
tions are met.
However, the communications mode setting must be set to IO-Link Mode, connected device verifica-
tion must be enabled for the port, and the device must match.
• Restoring settings is enabled in the Restoration Setting for the port.
• Backup data already exists in the IO-Link Master Unit and the existing backup data is different from
the parameter settings in the connected IO-Link device.
If backup fails, a warning-level device event is generated.

• Related Parameters
Set the parameters to the following values from the IO-Link Master Unit Configuration Tool.
You can also set the parameters with communications instructions addressed to the IO-Link Master
Units. Refer to 3-2 IO-Link Master Unit Parameters on page 3-3 for objects to access.

Conditions for Backing Up and Restoring Parameter Settings
When IO-Link Communications Start
The following conditions determine whether parameter settings are automatically backed up or re-
stored when IO-Link communications start.
• Whether connected device verification is enabled and whether the device matches
• Whether there is backup data in the IO-Link Master Unit and whether the IO-Link devices match
• The combination of the backup and restoration settings
