• DNP3 – “Distributed Network Protocol” version 3

• A powerful protocol to transmit data from Point A to Point B using

serial and/or TCP/IP communications.

• Open and public protocol

• Developed in the early 1990s to achieve standards-based

interoperability between Master stations and substation computer

systems in the electric industry.

DNP3 Overview

• Request/Response protocol

• A protocol to transmit data from Point A to

Point B using serial and/or TCP/IP

communications.

• Widely used and accepted

• Developed in the 1979

• Simple

Remote Sites Overview• 100+ remote sites monitored/controlled• 93% of sites utilize a legacy (early 1980s)

RTU• Combined sites with a legacy RTU with a

PLC• 7% used a mix of PLC Brands • Two distinct remote control systems

Long term needs• Focus on data quality• Modernize • Standardize
