Configuring 31
Automatic Data Storage
Download Enable
Default: Off
The data stored on the IOLM port is downloaded to the IO-Link device if:
This option is selected.
The data stored on the IOLM port contains the same Vendor ID and
Product ID as the IO-Link device connected to the port.
The data stored on the IOLM port is different than that of the IO-Link
device.
The IO-Link device requests an upload and the Automatic Upload Enable
option is set to Off.
If you change configuration parameters on the IO-Link device and want
the parameters to remain loaded on the IO-Link device, you must disable
the Automatic Download option because otherwise, the IOLM will reload
the data storage on the port down to the IO-Link device.
Do not enable both Automatic Upload and Automatic Download at the
same time, the results are not reliable among IO-Link device
manufacturers.
Validation Config
Device Validation Mode
(Default: None)
Device Validation Mode provides these options:
None - this disables Device Validation Mode.
Compatible - permits a compatible IO-Link device (same Vendor ID and
Device ID) to function on the corresponding port.
Identical - only permits an IO-Link device to function on the
corresponding port as defined in the following fields.
Vendor ID

- Serial Number
Vendor Id (0-65535)
This is required if you select a Device Validation Mode other than None.
Device Id (0-16777215)
This is required if you select a Device Validation Mode other than None.
Serial Num
This is required if you select Identical for the Device Validation Mode.
Data Validation Mode
(Default: None)
There are three Data Validation Modes:
None - no data validation is performed on the port.
Loose - the slave device's PDI/PDO lengths must be less than or equal to
the user-configured values.
Strict - the slave device's PDI/PDO lengths must be the same as the user-
configured values.
PDI Length (0-32)
This is the input length of the PDI data field.
