Fast, Local, Actionable, Secure Data
The Open Field Message Bus (OpenFMB) is a grid-edge interoperability standard that specifies common data models and unified protocol interfaces to democratize the utility ecosystem and enable distributed intelligence use-cases. OpenFMB reduces the need for centralized control and allows management of distribution systems at the circuit level.
OpenFMB also provides plug-n-play adapters to leading energy protocols (e.g., DNP3, Modbus, 2030.5, and OCPP), which enable federated data exchanges at the edge of the network and allow for secure peer-to-peer communication in a heterogeneous ecosystem of hardware devices and software applications.
Developed by an industry coalition of energy stakeholders within the UCA International Users Group, the OpenFMB data model was derived from IEC 61850 and IEC 61968/61970 (Common Information Model) and is publicly available in Unified Modeling Language (UML).
Introduction Videos
The OpenFMB Users Group is working with accreditation and testing labs to provide certification opportunities for vendors to obtain OpenFMB conformance certificates.
Please join us in this effort if you are:
- A vendor interested in conformance certification of their product.
- A lab or accreditation body is interested in offering this certification.
- An electric utility interested in improving the certification process.
Members of UCAIug’s OpenFMB Users Group have created and made available the use case documentation, data models, and test procedures.
To officially release these open-source artifacts without any royalties, OpenFMB working group participants are required to complete a Contributor License Agreement (CLA) before they can contribute to the creation and governance of OpenFMB User Group artifacts.
Featured Event
PlugFest 3.0
May 20-23, 2024 • Detroit, MI
In May 2024, UCA will be conducting its 3rd PlugFest in Detroit with DTE Energy as its host. The objectives are to validate vendor interoperability while sharing use cases and lessons learned to drive broader industry adoption of OpenFMB solutions.
OpenFMB Membership
The energy industry coalition consists of electric utilities, technology suppliers, national labs, and other stakeholders. Join UCAIug and the OpenFMB Users Group to participate and contribute to the adoption of OpenFMB.
