Version 1.0 released

The new version 1.0.0 added support for the SetFile service (MMS obtainFile service). The obtain file service is an optional service and can be disabled on resource restricted systems when required. The feature implementation also allows server side callback functions to allow or reject file uploads. With this new feature all of the file services and all of the standard services are implemented. The release also contains some other small improvements and bug fixes. Please download here.

First release of IEC 60870-5-104 protocol implementation in C and C#

I am happy to announce the lib60870 library for the implementation of the IEC 60870-5 standards based protocols. At the moment the library implements most parts of the standard IEC 60870-6-104. The library is released under the terms of the GPLv3 open-source license. Commercial licenses with fair and simple license conditions are available on request. The library contains two different implementations. One is written in C99 compliant C code and is intended to be used in embedded systems. The other is written in C#. Please find the source-code in the download section.

Smart Grid Technologies provides IEC 61850 consulting and implementation services

We proudly present our new service brand. Under the label “Smart Grid Technologies” we provide a broad range of services related to the implementation of IEC 61850 and other smart grid communication protocols (like IEC 60870-5-101/104, DNP3). From initial consulting and training up to implementation and standard conformance certification we can provide support in all the phases of evaluation and implementation of smart grid communication protocols into your devices and systems. Please check out our complete portfolio at In the future you will also find some more detailed technical articles there.

New release 0.9.2 with logging service support

I am happy to announce the new release 0.9.2 of the IEC 61850 library. This release contains a lot of small new features and stability improvements. The most notable change is the client and server side support for the logging ACSI service. Provided are new examples for client and server side usage of this service. A detailed tutorial will follow. For the server a generic interface is provided to support an application specific way to store the logged data. The library is delivered with an implementation of this interface using the sqlite database. With the addition of the logging service support for the IEC 61850 ACSI services is almost complete.
Please see the CHANGELOG for more information about changes and new features.

Release 0.9

This new release contains a lot of changes under the hood. These changes include some bug fixes as well as improvements to make the buffered reporting and file server module more compliant with UCA test cases. There are also some enhancements to the .NET API. A new feature of this release is the sampled values (SV – IEC 61850-9-2) subscriber implementation and the experimental publisher implementation. There are also new examples to show how to use the new features.

New release 0.8.7

Today’s release contains a lot of changes under the hood to improve standard compliance and interoperability with other implementations. There are also a lot of small bug fixes for bugs reported by users. This release also contains some smaller API enhancements especially for the .NET API. Be aware that the server side API changed at one point – the WriteAccessHandler that is used to inform the server application that some writable data attributes are accessed. The signature of these callback has changed! There is now a user defined parameter to simplify application design. Also the return value changed so the application designer can control the return code of the negative WriteData response. Don’t forget to change your application accordingly when updating to this release. Please see also the CHANGELOG for additional information about new features and changes.

HydroInterOp examples for hydro-power plant modeling

I uploaded HydroInterOp examples for libiec61850. These examples are provided by Denis Francesconi (Hydro Quebec) to show how to use data models for hydro power plants based on IEC 61850-7-410. The HydroInterOp examples are a forward step in the development of inter-operable and interchangeable plant level IEDs for hydro power plants (HPP), that is one step closer to having “HPP ready” certified IEDs. HydroInterOp is based on the ongoing work within IEC-TC57 WG18 to develop an implementable hydro information model and conformance test cases based on the IEC 61850 suite. Currently the WG18 is working on a conformance test case document IEC TS 61850-10-210.
The examples work with libIEC61850 version 0.8.4 out of the box. In order to be used with more recent versions of libIEC61850 the data models (static_model.c/.h) have to be recreated by the genmodel.jar tool.
