The data stored on the IO-Link Master port is downloaded to the IO-Link device if:
1. This option is selected.
2. The data stored on the IO-Link Master port contains the same Vendor ID
and Product ID as the IO-Link device connected to the port.
3. The data stored on the IO-Link Master port is different than that of the
IO-Link device.
4. 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 IO-Link Master 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.
The Manual Data Storage Ops option provides the following functionality, if data
storage is supported by the IO-Link device.
• CLEAR - this clears any stored data for an IO-Link device on this port.
• UPLOAD - this uploads and stores the IO-Link device configuration on the IO-
Link Master.
• DOWNLOAD - this downloads the stored IO-Link device configuration from the
IO-Link Master to the IO-Link device attached to this port if the Vendor ID and
Device ID match.
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
 Device ID
 Serial Number
This is required if you select a Device Validation Mode other than
The Vendor ID can be manually entered in this field or click the GET ATTACHED
button and the IO-Link Master propagates the Vendor ID in this field.
This is required if you select a Device Validation Mode other than
The Device ID can be manually entered in this field or click the GET ATTACHED
button and the IO-Link Master propagates the Device ID in this field.
This is required if you select Identical for the Device Validation Mode.
The Serial Number can be manually entered in this field or click the GET
ATTACHED button and the IO-Link Master propagates the serial number in this
field.
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.
