IEC 61850 Protocol Library

Source Code Library (libIEC61850)

The IEC 61850 source code library allows a fast and cost efficient implementation of the IEC 61850 protocols (MMS, GOOSE, Sampled Values) into devices and applications. The APIs are designed to be very easy to use. The basic library is written in C (C99 compliant to provide maximum portability). Due to its hardware and platform independent design it can easily deployed on any platform.

Technical Properties

  • Souce code in C99
  • Tested and certified
  • MMS client/server
  • GOOSE publisher/subscriber
  • SV (Sampled Values) publisher/subscriber
  • C#/.NET wrapper
  • Compatible with Edition 1 and Edition 2 of the standard.
  • dynamic data model creation
  • object-oriented design in pure C
  • Platform abstraction layer allows for easy adaptation to new platforms and operating systems
  • Drivers for Linux/ucLinux, Windows, and MacOS/BSD
  • Tested on x86/x64, Coldfire, ARM 7/9, ARM Cortex-A/Cortex-M7, PowerPC, MIPS
  • Multiple threading options for server implementation (multi-threaded, single-threaded, non-threaded)
  • field proven and certified devices available
  • configurable generation of server data models from SCL/CID file at runtime with DataModelFactory (commercial version only)
