1. OVERVIEW
This document defines the Distributed Network Protocol (DNP) V3.00 Transport Functions, Transport Protocol Data Unit (TPDU), as well as transport services and transmission procedures. Master stations, submaster stations and outstations or intelligent electronic devices (IEDs) can use these transport functions to pass messages between primary (originating) stations and secondary (receiving) stations. In this protocol, master stations, submaster stations and outstations are both originators (primary stations) and receivers (secondary stations).

HOW THIS SPECIFICATION IS ORGANIZED
1. OVERVIEW A general overview of the transport functions.
2. TRANSPORT FUNCTIONS A detailed description of the packet formats and transmission procedures.
In this document, the octet is a term used to refer to an eight bit-data object and is synonymous with the term byte. The low order bit of an octet is referred to as bit 0 and the high order bit as bit 7.
WHO SHOULD USE THIS SPECIFICATION
This specification is intended for communication engineers and programmers interested in knowing the function and message format of the DNP V3.00 Transport Functions. This includes programmers implementing and designing DNP V3.00 Transport Functions software/hardware and quality assurance personnel testing and verifying implementations of the DNP V3.00 Transport Functions. Application programmers may find this specification useful in determining how to interface with and make use of the DNP V3.00 Transport Functions. Familiarity with the ISO-OSI 7-layer model, IEC 3-layer EPA and IEC TC-57 standards is helpful.
