Distributed Network Protocol 3 (DNP3) is a set of communications protocols used between components in process automation systems. Its main use is in utilities such as electric and water companies.

DNP3 is based on the standards of the International Electrotechnical Commission (IEC) Technical Committee 57, Working Group 03 who defined an OSI 3 layer "Enhanced Performance Architecture" (EPA) protocol standard for telecontrol applications.

Dec 30, 2023 · Distributed Network Protocol 3 (DNP3) is a set of communication protocols used in utilities and process industries, primarily for electric, water, oil, and gas sectors. It’s used to enable communication between various types of data acquisition and control equipment.

DNP3 has grown to be the most widely used protocol for electric transmission and distribution communications in North America and other regions of the world, and is a named standard for DER communications.

DNP3 is network based device control protocol which is used for communication between a device and a remote input / ouput device. This protocol mainly depends on an object oriented model that decreases the data bit mapping that is usually …

DNP3 (Distributed Network Protocol) is a group of protocols. It plays an important role in SCADA systems, where it is used between system components. The protocol was specifically developed so RTUs could talk to one another.

DNP3 protocol either passes measured data from or control commands to the plant floor mechanisms by using multiple interconnected outstations. Outstations are considered processes at their core, but will typically be referred to as devices or …

DNP3 provides the rules for substation computers and master station computers to communicate data and control commands. DNP3 is a non-proprietary protocol that is available to anyone. Only a nominal fee is charged for documentation, but otherwise it is …

Jul 2, 2024 · DNP3 (Distributed Network Protocol) was developed by GE Harris to create a protocol specification for vendors of power grid SCADA (Supervisory Control and Data Acquisition) components to standardize on. Since 1993, this open and public protocol has been managed by the DNP3 Users Group.

Being an object-based application layer protocol, DNP3 has the flexibility to support multiple operating modes such as poll-response, polled report-by-exception, unsolicited responses and peer-to-peer. It permits multiple masters and encourages distributed intelligence. Users can expect many benefits from using DNP3. In the short term:
