  <code>options</code>.
  <p>
  There are two types of property adapters. One uses KNXnet/IP local device
  management to access KNX properties in an interface object, the other type uses
  remote property services. The remote adapter needs a KNX network link to access the
  KNX network, the link is also created by this method if this adapter type is
  requested.
  
  @param options contains parameters for property adapter creation
  @return the created adapter
  @throws KNXException on adapter creation problem
