7 Functions of IO-Link Master Units
Parameter settings are backed up and restored when IO-Link communications start only when con-
nected device verification is enabled and all devices verify.
The following tables show the backup and restoration conditions when IO-Link communications start
assuming that connected device verification is enabled and all IO-Link devices verify.

Clearing Backup Data

You can clear the backup data from IO-Link devices that is stored in the IO-Link Master Unit. The
backup data can be cleared when the IO-Link Master Unit is replaced with an IO-Link Master Unit to
which IO-Link device backup data was previously written or when you are not sure what connection
configuration the backup data is for.
If connected device verification is enabled, the parameter settings are backed up immediately after the
backup data is cleared regardless of whether or not there is a verification mismatch.
To clear the backup data, you can use either the CX-ConfiguratorFDT or a communications instruction
for the IO-Link Master Unit.
When the backup data is cleared, the backup data of all ports will be cleared.
