Latest release on maven central OpenIEC61850 on github

OpenIEC61850 is an open source implementation of the IEC 61850 standard licensed under the Apache 2.0 license. The library is written in Java and consists of an MMS client and server.


The software stack was designed with three main goals in mind:

  • Simplicity: The stack’s interface was designed to be easy to use, hiding the complexity of this extensive standard behind a simple API.
  • Scalability: Measurements as part of a dissertation have shown that OpenIEC61850 processing performance is comparable to that of high-performing C implementations.
  • Compatibility: The stack is written in pure Java and runs on all major operating systems including Windows, macOS, and Linux.

The OpenIEC61850 stack supports the following IEC 61850 services:

  • All GetDirectory and GetDataDefinition services
  • GetDataValues and SetDataValues
  • Data set services
  • Unbuffered reporting
  • Buffered reporting (client only)
  • Control services

The library also includes simple console client and server applications which can be used for testing and simulation purposes.

Development Partners

Now beanit partners with OpenMUC and MZ-Automation to support all your IEC 61850 needs:

OpenMUC Team for Application Development

The OpenIEC61850 project has been recently moved from to The OpenMUC team, a group of sophisticated software developers and researchers at Fraunhofer ISE, will continue to support the project but put their focus on developing applications based on IEC 61850. If you have needs for application development, they would make a great choice. They have much experience with using OpenIEC61850 to control DERs such as CHP units and PV inverters. In addition, offers a large number of other monitoring protocols such as IEC 60870-5-104 and a powerful OSGi based platform for monitoring and control.

C Stack by MZ-Automation

In case Java is not an option for you (e.g. if you want to implement a server on very resource constrained systems) you can also consider libiec61850 which is an IEC 61850 implementation in C by MZ-Automation.
