Source Type = 0 & Destination Type = 1
When the DPV1 Class 2 Init is initiated, and the Source Type (Source_Type) is 0 and
the Destination Type (Dest_Type) is 1, the AOI will set:
 The Source Address Length (Source_Addr_Len) to 2.
 The Destination Address Length (Dest_Addr_Len) to 16.
 The Ethernet/IP CIP Message Request length
(MSGDPV1CLASS2INIT.REQ_LEN) to 38.
 Copies all of the Destination address information tags (API, SCL, Network/MAC
Address) to the appropriate tags of the request message.

Source Type = 1 & Destination Type = 1
When the DPV1 Class 2 Init is initiated, and the Source Type (Source_Type) and
Destination Type (Dest_Type) are both 1, the AOI will set:
 The Source Address Length (Source_Addr_Len) and the Destination Address
Length (Dest_Addr_Len) both to 18.
 The Ethernet/IP CIP Message Request length
(MSGDPV1CLASS2INIT.REQ_LEN) to 56.
