Dnp Users Group - Company Information

The development of dnp3 was a comprehensive effort to achieve open, standards-based interoperability between substation outstations and master stations for the electric utility industry. since its inception, dnp3 has also become widely utilized in adjacent industries such as water / waste water, transportation and the oil and gas industry. in early 2010, the dnp technical committee began working with the ieee to establish dnp3 as an ieee standard; ieee standard for electric power systems communications – distributed network protocol (dnp3) was released as ieee std 1815tm-2010 later that year. this standard incorporated all of the individual "basic 8" volumes into one document, with each "basic 8" volume becoming a separate clause in the 1815-2010 document. since then, members of the dnp technical committee and ieee power & energy society, transmission and distribution (pe/t&d) committee and substations committee (pe/sub) – working group c12 have been working diligently to update various sections of the dnp3 specifications. the result is ieee std 1815tm-2012, which was released oct. 12, 2012. the updated dnp3 standard contains many changes, including dnp3 secure authentication v5, which defines a protocol mechanism that enables a dnp3 outstation/master to unambiguously determine that it is communicating with the correct user/outstation. ieee std 1815-2012 and the accompanying dnp3 specification supplement 1 - device profile template and xml schema are now available for download to dnp users group members from the dnp3 document library.
