Product overview
2.3 Replacement of the IO-Link Master CM 4xIO-Link communication module with an electronic coding element
type H
Master Backup
In addition to saving the parameters in the electronic coding element, you can back up the
parameters of your module, firmware version V2.2 or higher, with the function block
"IO_LINK_MASTER".
The "IO_LINK_MASTER" function block is used to read all relevant IO-Link device and
IO-Link master parameters. These can be stored retentively at a central location, such as in
a data block in the IO controller.
The status of the IO-Link devices or IO-Link ports stored in the IO-Link master can be
restored with the "IO_LINK_MASTER" function block.
As a result, the IO-Link ports and the IO-Link master are configured with the values stored in
the master backup.
A typical application is restoring the parameters after replacement of the IO-Link master.
Note
Availability
Note that the Master Backup function is available only for IO-Link devices that are specified
for the IO-Link Standard as of V1.1.
You will find further information on the Master Backup functions in section "Master backup"
of chapter "Integration into the automation system" of the IO-Link System
(https://support.industry.siemens.com/cs/ww/en/view/65949252) function manual.
