Addressing of a parameter. If several parameters are accessed, there are
correspondingly many parameter addresses. The parameter address appears only in the
request, not in the response.
Per addressed parameter, there is a segment for the parameter values. Depending on
the request ID, parameter values appear only either in the request or in the reply.
