IOL Device Validation
The IOL Device Validation (IO-Link Device Identification) lets you check the
connected devices for the values set in the control program in order to, e.g.,
identify correctly connected devices and not start operations with them.
Validation mode
Figure 15: IO-Link Device Identification
No validation
This option is the default setting. In this case, neither
the VendorID, DeviceID, nor the serial number are
synchronized after powering on between the IO-Link
device and the entered IO-Link Master data before
communication starts.
Compatible with entered values
With this option, the VendorID and DeviceID are
synchronized after powering on between the IO-Link
device and the entered IO-Link Master data before
communication starts. Process data communication is
only established if the configured values match the
values reported by the device.
Replacement of the an IO-Link device of the same type
is thus possible without changes in the Engineering
Tool.
Identical with entered values
In this case, the VendorID, DeviceID and serial number
are synchronized after powering on between the IO-
Link device and the entered IO-Link Master data before
communication starts. Process data communication is
only established if the configured values match the
values reported by the device.
