IEC 61850 Source Code Library

Our IEC 61850 Source Code Library provides a quick and cost effective way to implement an IEC 61850 Server, Client, GOOSE, or Sampled Values.  The library was designed from the ground up to fully support IEC 61850 services and efficiently use resources.  We offer our Library Components in ANSI-C, C++, or .NET Components for maximum flexibility across many different applications.

Key Additions to Recent Releases of ANSI-C Library

v11.0.3
- Added a common subscribe function for routable GOOSE (R-GOOSE) and traditional multicast GOOSE
- Implemented several Technical Issues (TISSUES) including TISSUE 1369 and 1091
- Improved handling of GOOSE messages after TAL expiration
- Improved timing resolution for Windows® implementations
- Updated examples for implementing IEC 61850 servers
- Update to Linux® static allocation of semaphores and events
- Improvements to time calculations with microsecond resolution
- Several other enhancements - see release notes for full list

v11.0.1
- Fixed issue with failure to disable report control blocks upon loss of two-party-assocation
- Improved GOOSE by fixing timeout miscalculation and unbind error
- Improved compiler warnings
- New macro to allow a modifier for functions likely to be exposed
v11.0
- This major release improves the library for more streamlined IEC 61850 implementations and builds on the 20 year track record of dependable code and high performance.
- A new build process is provided that more closely follows typical customer use. The library builds completely from the application directory to simplify integration into a larger project. Multiple configuration files have been condensed into a single directory with one header file and the application makefile.
-The code base has been significantly refactored in order to streamline library implementations and make debugging easier.
- The target layer has been abstracted and consolidated. Linux and WindowsTM targets are provided and OS specific code has been collected to make porting easier. The Linux target has improved threading and semaphore handling.
- A new consistent tracing mechanism has been added.  Applications can filter on messages for different library modules (like SCL parsing, transport, ACSI services, etc.) and can filter by message severity.
- Most examples have been simplified to more clearly demonstrate particular functionality.
v10.5
Initial support for routable Sampled Values and GOOSE (according to Part 90-5 of IEC 61850 standard) has been added. This new capability allows Sampled Values and GOOSE messages to be routed across wide area networks so that substations in different locations can share voltage, current, phase, and frequency data from phase measurement units. Sharing these accurate measurements and event data enables the implementation of Wide Area Measurement and Protection and Control (WAMPAC) systems to help stabilize large, interconnected power systems.

v10.4
Allow integrity & GI when there is connection but rptEna=False
Made changes to support Ed1 versus Ed2
Buffer integrity reports while there is no connection
Improved checking on MMS context pointers
TLS/SSL method support for PNNL
Added support for extRefs
Addressed IEC 61850 TISSUES from WG10

v10.3
Added updates for Schema 3.1
Added support for CRL updating
Improved parsing of SCL namespaces
Improved Client API reporting callbacks
Added optional compatibility with legacy IEC 62351 implementations
Added support for mixed Ed. 1/Ed. 2 systems
Added support for GOOSE Test flag
Added improvements to Tracking nodes
Updated classes and primitives for conformance testing
Added updates for Schema 3.1
Removed security checks for GOOSE/SAV (due to revisions to schema and IEC 62351)

v10.0
Added support for IEC 61850 Ed. 2
Created new XML modeling scheme
Added Ed2 Class models, Reporting and Logging Models, and Service Tracking
Added Analog control support (AnalogueValue structure as ctlVal)
Added IEC 62351 security
Changed to Ed2+Ed1 schema, adding nIedSclVersion and nSclVersion, and
changing control block instances
Changed to Ed2+Ed1 log control blocks and log definitions from SCL, including
domain specific
Added fileDirectory change (handle case of file argument to fileDirectory service
request)
Added settings Group Control Block support
Added support for arrays of SDOs
Allow for array elements in datasets
Added support which allows all Client write requests to automatically trigger
invoking evaluation handlers and reporting
