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.
Thank you to our Corporate Partner
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
Various activities meet with various cadences:
- Biweekly (virtual): Subcommittees on use-case data modeling or testing & certification
