2.2
Functions
IO-Link is a point-to-point connection between a master and a device. Both conventional and
intelligent sensors/actuators can be used as devices at the IO-Link via unshielded standard
cables using proven 3-wire technology. IO-Link is backward compatible to conventional
sensors. The switching state and data channels are designed with trusted 24 V DC
technology.

2.3
Replacing the IO-Link Master CM 8xIO-Link communication module
Master Backup
You can back up the parameters of your module with the function block
"IO_LINK_MASTER_8".
The "IO_LINK_MASTER_8" function block is used to read all relevant IO-Link device and
IO-Link Master parameters. The parameters 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_8" 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 the restoration of parameters after replacement of the IO-Link Master.
