About the Common Information Model (CIM) Standard
Understanding CIM
• Standard to exchange meter data among enterprise
application software commonly used in utility
companies
– Provides a common way to represent the computing and
networking elements that make up a business' systems,
and the relationships between theseelements
• Intended to assist vendors and utilities in
development of interfaces that:
– Enable software products from various vendors to
interoperate without extensive custom interface
development
– Are independent of platform or database structure
5
Brief History of the Standard
Understanding CIM
• Created by the Unified Information company
• Developed and submitted to IEC by the Control
Center Application programming Interface (CCAPI)
Task Force, a working group supported by the Electric
Power Research Institute (EPRI)
• Standard adopted in 2001
• Gas and Water utility service support added
• Part 9 covering interfaces for meter reading and
control approved August 2009: IEC 61968-9
Edition 1.0 2009
• Maintained by working group 14 of Technical
Committee 57 of the IEC (IEC TC57 WG14)
6
Key CIM Terminology
Understanding CIM
• Standard defined in terms of Operations
– Correlate to individual tasks to perform
• Collection of related operations = Function
• Collection of related functions = Gateway
– Interacts with the RNI
– Sensus CIM gateway = CIMv1 gateway

Operation
Understanding CIM Operation
Understanding CIM
• Sensus implementation uses the publish/subscribe
model
• Publishers create and send messages
– For example: on-demand meter reads or power status
– Zero or more subscribers receive the message
• Subscribers register to receive messages
• Neither the publisher nor the subscriber knows
about the other
– Like an anonymous bulletin board
• Subscribers must remain continuously active to
receive messages

CIM Communications
Understanding CIM
•
•
•
•
Exchange messages via Java Message Service (JMS)
JMS message body contains CIM message
CIM message contains CIM header
CIM header contains:
– Correlation Id used to associate requests with response
– Verb/noun elements used to characterize the message
• Messages are exchanged using specified patterns

Error Reporting
Understanding CIM
• Errors encountered during request processing are
reported to the client either:
– Through JMS fault messages
– By elements inside the CIM response payload
• Determined by the nature of the error
– Errors, such as system and security errors, that cause the
entire request to fail use JMS fault messages
– Business errors, related to objects within the request,
typically use error objects in CIM response payload
– Low level business errors, e.g. meter asset identification,
use a reply code, and sometimes an error object, in the
CIM response payload

About the CIMv1 Gateway and the RNI
CIM Solution
• Applies only to electric end points
• Accesses RNI functionality through a well defined
interface
• Translates from internal RNI data structures to
external CIM data structures
• Communicates with JMS messages to and from
remote broker queues
• Relies on transport security provided by the JMS
broker vendor (e.g. SSL) and optionally, JNDI
resource credentials (no encryption support)
• Compatible with IBM WebSphere, Oracle WebLogic,
Apache ActiveMQ JMS brokers

Remote system publishes request to JMS broker (at utility)
Broker places request on designated queue
CIM gateway listens for (subscribes to) requests on specified broker queues
CIM gateway validates the operation code of request and replies with OK or error
to designated location
RNI performs request, obtaining indicated data from the database or meter
RNI publishes the result to RNI JMS broker response queue
CIM gateway listens to RNI broker response queues
CIM gateway translates RNI responses to CIM and publishes to JMS broker at utility
About the Utility JMS Queues
CIM Solution
• On Demand Request Queue
– All request messages arrive for the CIMv1 gateway via this
queue
• On Demand Response Queue
– All responses and messages originating from the CIMv1
gateway are delivered to this queue
– Multiple functional areas within the CIMv1 gateway
publish to this queue
• Unsolicited Read Publication Queue
– Destination for all unsolicited Interval reads and register
reads
• Unsolicited Event Publication Queue
– Destination for all unsolicited meter event notifications
27
More About the Utility JMS Queues
CIM Solution
• Sensus CIM gateway interrogates the utility JAVA
Naming and Directory Interface (JNDS) server to look
up physical queue names
28

30
On Demand Reads
CIM Solution
• Requests meter readings such as energy and peak

the meter if a scheduled interval start/end time is
NOT provided
• Accepts a single end device asset
• Reading type code determines the read request type
