Reference
The IO-Link block library with a description of the integration is available on the Internet
(

).
You can find an application example of using the block library with HMI devices on the Inter
net (

).

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 automatically 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.
Figure 3-6 Overview of data backup level in S7-PCT
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).
