Introduction Scope/Purpose Reference Model Information Models Meter Reading and Control Messages 2 © Copyright 2010 SISCO, Inc. 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 3 © Copyright 2010 SISCO, Inc. 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 4 The Reference Model describes the flows between the components. © Copyright 2010 SISCO, Inc.

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 9 © Copyright 2010 SISCO, Inc. Message Types The key message payload structures include: CustomerMeterDataSet MeterAsset MeterAssetReading EndDeviceControls EndDeviceEvents MeterReadings MeterReadSchedule MeterServiceRequest MeterSystemEvents EndDeviceFirmware 10 © Copyright 2010 SISCO, Inc. EndDeviceEvent Messages EndDeviceEvent Messages Convey events related to: Sustained Outage Detection Momentary Outage Detection Low Voltage Threshold Detection High Voltage Threshold Detection Distortion Meter Health Tamper Detection Revenue Event 11 © Copyright 2010 SISCO, Inc. EndDeviceAssets Message 12 © Copyright 2010 SISCO, Inc. CustomerMeterDataSet Message 13 © Copyright 2010 SISCO, Inc. 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 © Copyright 2010 SISCO, Inc. 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. 15 © Copyright 2010 SISCO, Inc. 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. © Copyright 2010 SISCO, Inc. EndDeviceControls Message 17 Specific Meters may be addresed by CustomerAgreement, EndDeviceAsset and/or EndDeviceGroup At least one address and a typeControl attribute is required for this message TypeControl element identifies the type of control to be performed © Copyright 2010 SISCO, Inc. MeterServiceRequests Message 18 May include one or more MeterServiceWork items Each item may refer to a max of two meters to provide a means to replace a meter. Meter readings can be obtained as a part of the work. © Copyright 2010 SISCO, Inc. MeterSystemEvent Message 19 Supports the reporting of activity within any type of end device (including meters), as well as within the MS communication infrastructure Can be used to describe an event in the end device itself, or in the MS communication infrastructure © Copyright 2010 SISCO, Inc. EndDeviceFirmware Message 20 Supports the naming of the affected device function, as well as additional parameter details that may be necessary in the report This structure, together with the ActivityRecord can effectively describe the nature of the event, when the event occurred, and what has happened © Copyright 2010 SISCO, Inc. ReceiptRecord Message 21 When MS receives a payment, a receipt is generated and the relevant information about the payment is typically recorded as a receipt record. This information may be accessed by means of ReceiptRecord message payload. © Copyright 2010 SISCO, Inc. TransactionRecord Message 22 Information about the sale of a prepaid token or the receipt of an account payment is typically recorded by MS in the form a financial transaction record © Copyright 2010 SISCO, Inc. SupplierConfig Message 23 Information about the supplier (retailer or utility for example) of the service may be configured into MS by means of SupplierConfig message payload © Copyright 2010 SISCO, Inc.
