3.7.1.3 SIO Digital In/Out Module Parameters
Use the following procedure to configure SIO digital in/out module parameters.
1. Double-click an SIO Digital In or SIO Digital Output module.
2. Select the Parameters table. Available parameters are shown in the next two images and the table
describes SIO digital input and output module parameters.

IO-Link Port Module Parameters
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.
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 None.
This is required if you select a Device Validation Mode other than None.
This is required if you select Identical for the Device Validation Mode.
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.
This is input length of the PDI data field.
This is required if you select a Data Validation Mode other than None.
This is input length of the PDO data field.
This is required if you select a Data Validation Mode other than None.
