About the DNP3 software
The DNP3 (Distributed Network Protocol) software in the D400 is layered to be consistent
with the International Electrotechnical Commission (IEC) Enhanced Protocol Architecture
(EPA); see Figure 56.
The protocol software comprises a Physical Layer, Data Link Layer and Application Layer.
Both the DNP3 client and server applications implement the Application Layer and Data
Link Layer and support the serial Physical Layers. The Ethernet layer is implemented using
separate software, the DNP3 Transport Layer application.
