3.3 Changing and saving device parameters during plant operation
Changing device parameters
You can adjust the device parameters during operation.
The changed parameters will become effective on the device in the process and are
retentively saved in the device.
The parameters can be adapted during operation with:
● the engineering tool used (e.g. during plant commissioning)
● the CPU user program (program-controlled)
● HMI (through plant operator during batch change, process optimization)
● Locally through operation on the device (local operating unit on the device)
Saving device parameters (backup)
You can also save the parameters set in the device during commissioning or changed during
operation of the plant in the IO-Link master.
This data backup takes place depending on the set behavior of the IO-Link master ports.
You can set the following data backup levels:
● None
No data backup in the IO-Link master.
● Backup&Restore
Every time the device parameters are changed, the changed data is automatically saved
in the IO-Link master (see section "Triggering a backup").
● Restore
No automatic data backup in the IO-Link master.

Note
IO-Link Specification V1.0
IO-Link master and devices to IO-Link specification V1.0 do not offer this function; a data
backup cannot be set (Data backup: None).
Note that the behavior of the IO-Link master and the IO-Link devices during device
replacement depends directly on the set data backup level.
You can find additional information on this dependency in the section Replacing a master or
device during operation (Page 32).
