Scope/Purpose



To Define the exchange of information between a
Metering System and other systems within the Utility
enterprise
Specifies the information content of a set of message
types that can be used to support many of the
business functions related to Merter Reading and
Control.
Typical uses of the message types include:
 Meter Reading and Meter Control
 Meter Events
 Customer Data Synchronization and Customer Switching

Reference Model



The Reference Model provides examples of the logical
components and data flows related to this standard.
The Meter is treated as an “end device”
An End Device:
 Has a unique identity
 Is managed as a physical asset
 May issue events
 May receive control requests
 May collect and report measured values
 May participate in utility business processes


The Reference Model describes the flows between the
components.

Information Model


The Static Information Model that contains the
metering classes, attributes and associations is
defined in detail in IEC61968 Part 11 or in IEC61970
Part 301.
Classes for Meter Reading and Control are contained
in the following Packages:
 Asset classes are defined in Asset package in 61968-11
 Customer classes are defined in the Customer package in
61968-11
 Metering classes are defined in the Metering package in
61968-11
 Prepayment classes are defined in the PaymentMetering
package in 61968

MeterReadSchedule Message

Meter readings may be
requested using one or more
of the following parameters:
 Specific meter, using the
EndDeviceAsset mRID

Specific meter, using a
serialNumber as known to the
Metering System

EndDeviceGroups, where
an EndDeviceGroup identifies
a groupAddress used within
the Metering System

As specified using a
TimeSchedule

ReadingTypes can be
specified to identify the
desired reading types
14

MeterReadings Message

MeterReadings message
allows for:
 Readings from one or
more meters
Reading values each
have an associated
reading type, timestamp
and value

Many Quality values can
be associated with each
reading value

Readings can be
supplied in the form of
interval blocks if the
common reading types are
grouped together.

Event Histories are
returned with meter
readings.

MeterAssetReading Message



16
MeterAssetReading
messages may contain
many MeterService
Work items.
Each
MeterServiceWork item
identifies a MeterAsset
and Customer
There may be many
Readings and
EndDeviceEvents
obtained from the
MeterAsset.



21
When MS receives
a payment, a receipt
is generated and the
