Value range
0x00 DS_DISABLED: DS mechanism is inactive and the complete pa-
rameter set of this port remains stored.
0x01: DS_ENABLED: DS mechanism is active and provides the full data
storage functionality (backup and/or restore).
0x02: DS_CLEARED: DS mechanism is disabled and the stored parame-
ter set of this port is cleared. (no no restore)

DS_ENABLED:
Restore (= download) and backup (= upload) – functionality (dependent on the status of the “Data
Storage Download Enable” + “Data Storage Upload Enable” parameters):
Activates the function for downloading parameter data from the master to the IO-Link device (=
download), as well as for uploading data from the IO-Link device to the master (= upload).
Backup (= upload):
Prerequisites:
– “Data Storage Upload Enable” = true;
– Any existing “Data storage lock” or “Parameter storage lock” in the IO-Link device must not be acti-
vated.
An upload is performed if an IO-Link device is connected, but there is no valid data in the master. The
read parameters are permanently stored in the master. The parameter data in the master can be over-
written by executing the “Force upload of parameter data into the master” command (ISDU index
0x0002, value 0x05) in the device. This allows device parameter data changed at runtime to be manu-
ally updated in the master.
Restore (= download):
Prerequisites:
– “Data Storage Download Enable” = true;
– Any existing “Data storage lock” or “Parameter storage lock” in the IO-Link device must not be acti-
vated.
If a new connection to an IO-Link device is established, the master compares the stored parameter
data with the data from the device. The master downloads the stored data to the device if there are
any discrepancies.
•
DS_DISABLED:
Data storage is deactivated. Stored parameter data in the master remains available.
•
DS_CLEARED:
Data storage is deactivated. Stored parameter data in the master is deleted.
