This attribute designates a license limit on the number of devices which may be added to this specific driver network in the
station database. Above this limit, any added device component (and all its child components) will be in fault.
This limit has no impact on the actual physical limitation of a field bus. For example just because the lonworks feature is
set to device.limit="none", this does not mean that you can exceed the normal limit of 64 devices per segment.
