If the DP configuration of a CP 342-5
includes only one or multiple slaves that only have outputs, it is
not necessary to call the FC 2 "DP_RECV".
In some older versions of the CP 342-5 DA 02 (firmware V5.0) you
must use FC 2 "DP_RECV" with a data length of 0 bytes or use
"dummy" inputs. You must define the ANY pointer required by the
DP_RECEIVE call with a data length of 0 bytes.
