Safety software library DNP3

communicationsinteroperabilityembedded

DNP3 is one of the most popular protocols used for communication between control centers (e.g. SCADA systems) and intelligent electronic devices (IEDs) installed at substations. In addition to the traditional electric utilities, it is also used in hydropower companies or gas suppliers. The DNP protocol was created in 1990 by Westronic, Inc. (now GE Harris). The standard has been designed on the basis of 60870-5-101:2003 with the addition of specific functionality needed for North American applications. Currently DNP3 is an open and public protocol, maintained by the Users Group. The latest version of the standard IEEE Std 1815-2010 was released in 2012. DNP3 library implemented by JPEmbedded is easily portable to any device with or without an operating system. It supports both, outstation and master side, serial and TCP operation modes. The implementation in C++ language takes into account requirements specific for embedded platforms, which are: * resource efficiency, * high configuration flexibility, * HW platform independence. DNP3 library supports level 3 interoperability and the following features: * static data points (class 0), * events (class 1-3), * reading / writing of data objects, * control operations, * data freeze, * cybersecurity (IEC 62351).
