Protection Mode for IO-Link Devices
Protection Mode is a state where the IO-Link device is operational and disruptive changes
that would take the product out of service are not allowed.
Enter and Exit Protection Mode
The IO-Link device enters Protection Mode as soon as the connection to the device is
established and exits Protection Mode as soon as the connection to the device is
closed.
Restrictions Imposed By Protection Mode
Protection Mode prevents access to services that are not required after the IO-Link
device is configured and in normal operation. Protection Mode disables features that
can make the device vulnerable to disruptive actions. By doing so, Protection Mode
helps to reduce the attack surface.
When the IO-Link device is in Protection Mode, the device prevents execution of the
following tasks:
- Perform remote device resets
- Perform device firmware updates
- Perform unconnected messaging to the Service Parameter object of the device
- Perform connected messaging to the Service Parameter object of the device from a node other than the owner-controller
- Change Electronic Keying parameters
- Change data storage mode
- Delete data storage
