Page 51: Unit Locking / Data Storage (As From Io-Link V1.1)
After a factory reset (button "Restore Factory Settings"), the device reboots and the factory settings are restored. 16.2 Unit locking / data storage (as from IO-Link V1.1) The IO-Link master stores all parameters of the connected sensor (except tank adjustment, see above) if configured in the master (data storage). When a sensor is replaced by a sensor of the same type, the parameters of the old sensor are automatically written to the new sensor if configured in the master and if the new sensor has the factory settings.
