IEEE 1815-2010

This document specifies the DNP3 protocol structure, functions, and application alternatives. In addition to defining the structure and operation of DNP3, the standard defines three application levels that are interoperable. The simplest application is for low-cost distribution feeder devices, and the most complex is for full-featured master stations. The intermediate application level is for substation and other intermediate devices. The protocol is suitable for operation on a variety of communication media consistent with the makeup of most electric power communication systems. The standard consists of several clauses each related to an application or function. The purpose of this standard is to document and make available the specifications for the DNP3 protocol. While a primary focus of this protocol is the Electric Utility Industry, other industries that deliver Energy and Water are also using DNP3. The intent of this DNP3 standard is to meet the goal established by the National Institute of Standards and Technology (NIST) for a Smart Grid protocol: ⎯ Provides a protocol standard from a recognized standard institution ⎯ Provides interoperability with hundreds of operational systems and thousands of devices ⎯ Provides cyber security based on IEC/TS 62351-5 ⎯ Provides Device data profiles in a format that can be mapped to IEC 61850 Object Models Vendors may use this standard to implement and test the protocol in their products and be assured of interoperability. Users may use the document to specify the features they wish to apply. System Integrators may use this standard to assist in system integration and testing. New IEEE Standard - Superseded. The DNP3 protocol structure, functions, and application alternatives and the corresponding conformance test procedures are specified. In addition to defining the structure and operation of DNP3, three application levels that are interoperable are defined. The simplest application is for low-cost distribution feeder devices, and the most complex is for full-featured master stations. The intermediate application level is for substation and other intermediate devices. The protocol is suitable for operation on a variety of communication media consistent with the makeup of most electric power communication systems.
