Configuring the IO-Link
6.5 Replacing an IO-Link device
6.5.2.3
Procedure without PG/PC
Requirements
• Implement the LIOLink_Device function block in the S7 program.
You can download the LIOLink_Device function block and the description from the Internet
(https://support.industry.siemens.com/cs/ww/en/view/82981502).
On completion of commissioning, a PG/PC with the project is no longer available. For backing
up and restoring the parameter data and configuration data from or to a module, the
LIOLink_Device function block is available for the SIMATIC S7 controllers.
With this function block, you back up all relevant data records of a module after
commissioning, in a data block (DB), for example. In the event of a replacement,
you write the relevant data from the data block to the replaced module with
the LIOLink_Device function block.
Refer to the Appendix "Data sets (Page 110)" for data records to be backed up in the case of a
module.
Procedure
1. Install the block library for IO-Link
82981502).
2. Use the LIOLink_Device function block as described in the documentation.
3. An application example for using the device-specific blocks from the block library for IO-Link
(LIOLink) can be found on the Internet
view/90529409).
Note
An IO‑Link device is a module that communicates with the IO-Link master via its communication
connection. With the special cases "SIRIUS 3RA64/65 compact starter" and "SIRIUS
3RA2711 function modules", where group formations of up to four starters are possible, the
above information refers to the replacement of the first load feeder. Replacement of load feeders
2 to 4 of a group of four does not require any supplementary measures.
6.5.3
Replacing an IO-Link device according to the IO-Link communication
specification V1.1
Automatic saving of parameter data
If IO‑Link masters and IO‑Link devices according to the IO‑Link Kommunikations-
Spezifikation V1.1 are available, the "parameter server" function can be used to automatically
back up parameter data.
When devices are replaced, this parameter data is written back to the new IO‑Link device
automatically on system startup.
