Source code 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.
  • 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, PowerPC, MIPS
  • Multiple threading options for server implementation (multi-threaded, single-threaded, non-threaded)
  • field proven and certified devices available

C#/.NET component

The C# library allows to create a managed DLL component that can easily be deployed in .NET applications. It is a wrapper of the C library. It can be used to be integrated into GUI applications, SCADA systems ...

  • Compatible with Microsoft .NET framework and Mono
  • Runs on Windows, Linux and other platforms supported by .NET and Mono
  • Very easy to use API
  • Support for MMS client/server


  • Communications in Substations (MMS/GOOSE/SV)
  • Communications for Wind Power Plants (IEC 61400-25)
  • Communications for Decentralized Energy Resources (DER - IEC 61850-420)
  • Intelligent Electronic Devices (IED)
  • Measurement Devices
  • SCADA Systems
  • Monitoring
  • Test systems
Platform independent source code library
