      Specifying auto-apply constraints allows you to limit the scope where the device protocols are
      applied, for example by specifying a set of possible servers or node IDs.
    </p>
    <p translate>
      If no constraints are set, device protocols are applied at any fitting location on the OPC UA
      server.
