Combining IO-Link devices with different specifications
Only devices of specification V1.0 can be operated on IO-Link masters of specification V1.0.
Devices of specification V1.0 and V1.1 can be operated on IO-Link masters of specification V1.1.

Data storage mode
NOTE
Data storage mode is only available for devices complying with the IO-Link specifica-
tion V1.1.
Data storage mode makes it possible to replace IO-Link devices without the need for a reconfig-
uration.
The IO-Link master or the IO-Link device save the device parameters set in the previous config-
uration. In data storage mode the parameter data memories of IO-Link master and IO-Link
device are synchronized. If data storage mode is activated in the IO-Link master, the master
writes the stored device parameters to the new device after a device is replaced. The applica-
tion can be restarted without having to perform a new configuration.
