IEC60870-5-101/104

C Source Code Library

C Source Code Library

Our library offers essential support for Companion Standard 101 (CS101) and 104
(CS104) of the IEC standard series, vital for telecontrol applications (IEC 60870-5). Widely employed for communication between central stations (controlling station) and outstations (controlled station) in electrical power systems.
The C source code library enables swift and cost-efficient implementation of IEC 60870-5-101 and IEC 60870-5-104 protocols in embedded devices and applications. Designed with intuitive APIs for ease of use and flexibility, this library is written in C (C99 compliant for maximum portability). Its hardware and platform-independent design ensures seamless deployment across various platforms, enhancing
accessibility and efficiency.
