DNP was originally developed by Westronic, Inc. (today General Electric). Since 1993, the [ DNP User Group ] is responsible for the further development of this protocol.
Originally the procol was called "DNP V3.00". Today the official name is "DNP3". In 2010, DNP3 was published as IEEE 1815-2010, meanwhile updated to [ IEEE 1815-2012 ] .
The DNP3 protocol family is widely used, particularly in the American/Pacific region.
DNP3 serial is used as a general transmission protocol between control systems and substations (RTUs, Remote Terminal Units). It has general abilities within the context of SCADA applications.
The messages are generally transmitted through serial connections. The frame format is abutted to FT3.

DNP3 over LAN/WAN is intended for connections through internet protocols. Both TCP/IP and UDP/IP can be used as transport layer. DNP3 over LAN/WAN has the same messages and the same frames format as DNP3.
