DNP3 - Wikipedia
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. Usage in other industries is not common.
Overview of DNP3 Protocol
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.
DNP3
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 Data Model & Data Types • DNP3 models data in terms of one-dimensional arrays of data per outstation: • Binary inputs & outputs • Analog inputs & outputs • Counter inputs (running & frozen) • Blob (“string”) objects • Data sets (structures of data) • Data identified by • Outstation, data type & index
DNP3 Communication - Distributed Network Protocol 3
2023年12月30日 · DNP3 is a layer 2 protocol that operates on either the physical and data link layers (Layers 1 and 2) of the OSI model or over TCP/IP network architectures (Layer 3 and above). It can support various types of hardware communication links, including serial (RS-232/RS-485) and Ethernet.
DNP3 Communication Protocol Overview - Inst Tools
What is DNP3? DNP3 is a communications protocol used in SCADA / “remote monitoring” systems. It has become very popular because it’s “open”. Any manufacturer can develop DNP3 equipment that is compatible with other DNP3 equipment.
Benefits of DNP3
About / Benefits of DNP3. Because DNP3 is based on the IEC 870-5 requirements, DNP3 is suitable for application in the entire SCADA environment. This includes RTU to IED communications, master to remote communications, and even peer-to-peer instances and network applications.
