Data validation is supported by many IO-Link devices. You can use this procedure to configure data validation.
Open the IO-Link Master embedded web interface.
Click Configuration | IO-Link Settings.
Click the EDIT button on the port you want to configure for data validation.
Select Loose or Strict to enable Data Validation.
Loose - the slave device's PDI/PDO lengths must be less than or equal to the user-configured values.
Strict - the slave device's PDO/PDO lengths must be the same as the user-configured values.
Click the GET ATTACHED button or manually enter the PDI and PDO length.
Click the SAVE button.
