2. OpenFMB™: The Catalyst for Interoperability
Open Field Message Bus (OpenFMBTM) is a reference architecture and framework for distributed intelligence and grid-edge interoperability
Leverages existing standards to federate data between field devices and harmonize them with centralized systems
Utility industry standardized semantic models
IEC’s Common Information Model (CIM) used in first reference implementation
Harmonized CIM & IEC model to be used for second reference implementation
Internet of Things (IoT) publish/subscribe protocols
DDS: Data Distribution Service
MQTT: Message Queue Telemetry Transport
AMQP: Advanced Message Queue Protocol
Scales operations independently, without a system-wide rollout
Flexible integration of renewables and storage with the existing grid
Accelerates ability to stack operational benefits
OpenFMB™ RMQ.26 standard was ratified in March 2016 by the North American Energy Standards Board (NAESB)

OpenFMB Data Model Task Force Update
Continued
OpenFMB Data model
Use of 61850/CIM harmonization model: include Logical node (LN)
Model structure: Common module & individual modules
Restricted data types: Enumerations and Specialization
Model management (centralized server proposed)
Use 61850/CIM harmonization with MeasurementValueSource & MeasurementValue as profile foundation
Specialization:
Specialized IED at root (e.g. ResourceReadingIED)
Specialized MeasurementValue (e.g. ResourceReadingMeaValue)
Specialized IEC LN (e.g. ResourceReadingMMXU)
Specialized data types (e.g. MV, BCR and etc.)
Common module package
Harmonization of OpenFMB profiles for Reading, Status, & Control

Publish / Subscribe Communications
Node Characteristics
Configuration management

13. OpenFMB Management Services Task Force Update
Management Services Subcategories
Subcategory
Description
Examples
Health Management
The management services layer with functionality that assesses, reports, and corrects the health of both individual nodes and the overall infrastructure
Metrics, alerts, and logging.
Lifecycle Management
The management services layer with functionality for installation, through updates, and to decommissioning of individual nodes and overall infrastructure
Installation, updates, and decommissioning.
Objectives
Develop a management services layer information model
Define the actors involved in the Management Services layer and how they interact
Identify, prioritize, and create high priority use cases, such as:
Health Metrics Time Series (Counter, Gauge, Related Statistics)
Alerts (Current or imminent user impact, Otherwise undetected, Actionable)
OpenFMB Updates (OpenFMB Applications, Interface Layer, Pub/Sub Layer, Administration)
OpenFMB Node Installation (Node Inventory, Configuration Definition, Lab Test Configuration, On-Site Installation)
