The IEC 60870-5-103 is a companion standard for power system control and associated communications. The standard enables interoperability between protection equipment and devices of a control system in a substation. 103 defines communication for serial, unbalanced links only. The standard was introduced by the IEC in 1997.
JPEmbedded’s implementation of IEC 60870-5-103 includes both master and slave-side functionality. The library is platform-independent and can be integrated on different targets, including bare-metal. The library is implemented in C++.
