CENTRON® Bridge Functional Overview iii Proprietary and Confidential

The CENTRON Bridge meter is the bridge between Itron communication architectures that enable Advanced Metering Infrastructure (AMI) and smart grid functionality. The meter’s adaptability allows it to be incorporated alongside existing Itron electric meters with a mobile meter data collection system, delivering advanced metering benefits associated with remote service disconnects, demand metering (real-time resetting), net metering, time of use rates, and interval data for customer service and engineering.

When prudent for the utility, the CENTRON Bridge can easily migrate to a full smart grid solution, offering demand response and distribution automation benefits. With CENTRON Bridge’s versatility and proven operational benefits, utilities can address current business challenges and see an immediate return on investment, all while readying for a full smart grid solution as the need develops. Enabled to leverage field assets across two different data collection solutions, a utility can protect and extend its original investment.

About This Document This document provides a high level overview of Itron’s CENTRON Bridge meter and the CENTRON Bridge Polyphase meter. This document also provides information on how you can deploy these meters to migrate from an Itron ChoiceConnect® environment to an Itron OpenWay® network, and considerations that should be taken into account when designing your operational mode transition plan.

After transitioning to OpenWay mode, the meter becomes compatible with OpenWay systems. See the OpenWay documentation suite for information about using the CENTRON Bridge in OpenWay mode.

Overview

CENTRON® Bridge Functional Overview 4 Proprietary and Confidential

The CENTRON Bridge meter is installed just like any other electric meter. Just take the meter into the field and physically install it. When the CENTRON Bridge meter powers up it is in AMR (ChoiceConnect®) mode. This means that it is transmitting an SCM+ message every 30 seconds. The SCM+ message contains the consumption reading, tampers, errors, service switch status, ERT Type(14), and ERT ID. While in AMR mode the meter is read using the Field Collection System (FCS) with an MC3, MCLite, or FC300SR collection device. Additional two-way commands can be used to interface with the meter for:

• Collecting up to five different energy values

• Collecting two channels of interval data

• Collecting demand readings and resetting the demand

• Disconnecting or connecting service

• Collecting Time of Use data

• Updating Time of use calendars in the meter

• Modifying the security state of the meter

• Scheduling the transition from mobile to OpenWay

When the CENTRON Bridge meter is transitioned to operate in OpenWay RFLAN mode it assumes all operating characteristics of the HW 3.1 OpenWay meter.

Note Register firmware 3.032.xxx and 5.008.xxx are the only versions of OpenWay register firmware that support communication with ChoiceConnect Mobile meter reading software. CENTRON Bridge meters with ChoiceConnect comm module firmware version 0.21.xx must have register firmware version 3.032.xxx. Meters with ChoiceConnect comm module firmware version 0.30.xx must have register firmware version 5.008.xxx.

CENTRON Bridge Meter Operation

CENTRON® Bridge Functional Overview 5 Proprietary and Confidential

CENTRON Bridge Meter Operation

Bridge Meter Functionality When deployed in a ChoiceConnect environment, the CENTRON Bridge meters provide the following extended functions, each of which is explained in its own section of this guide.

• SCM+ Message Format

• Enhanced Security

• Disconnect/Connect Service Switch (CENTRON Bridge single phase only)

• Reset Demand

• Tamper Detection

• Time of Use

• Retrieval of multiple energies and a variety of register values

• Load Profile Data Collection and Storage Values

SCM+ Message Format The CENTRON Bridge meter uses Itron's standard consumption message (SCM)+ message format. The SCM+ introduces the following capabilities:

• Larger endpoint ID. The SCM+ carries up to a 10-digit Type 14 ERT ID number.

• Larger reading field. The SCM+ includes a 8-digit reading field. This larger reading field allows the collection of larger values and more granular data.

• More tamper and status indicators. The SCM+ can include up to 11 tamper and status indicators. This increase in the number of indicators improves reporting capabilities to include meter removal, meter status such as Service Switch state and other events such as configuration changes.

CENTRON® Bridge Functional Overview 6 Proprietary and Confidential

CENTRON Bridge Meter Operation

ChoiceConnect Enhanced Security In ChoiceConnect mode the CENTRON Bridge meter can be configured to run at any of three security levels, each of which determines which meter features are available for use.

• Ready to secure. At this level no enhanced security is enabled. The meter responds only to read commands, which pull data from the meter but do not change the meter’s settings. The meter’s remote connect and disconnect, demand reset, and operation mode change features are unavailable.

• Command security. At this level you must use secure commands to access the meter’s remote connect and disconnect, demand reset, and operation mode change functions. It does not require the use of secure commands for reading meter data.

• Full security. At this level the meter requires the use of secure commands for all command and reading functions.

CENTRON Bridge meters arrive from the factory in ChoiceConnect operation mode with command security enabled. Your utility’s public key along with the factory, revocation, recovery, and command keys are all injected into the meter during the manufacturing process. After the meter is installed, you can use supported versions of Field Deployment Manager (FDM) or Field Collection System (FCS) with Itron Security Manager to change the meter’s security level if desired and to obtain the security keys and secure commands required for the security level in which you want to operate the meter.

During the transition from ChoiceConnect mode to OpenWay mode, security keys are used in conjunction with the OpenWay Collection Engine to transfer the production keys that the meter requires to operate in an OpenWay enhanced security mode. After the meter’s operation mode is changed from ChoiceConnect to OpenWay, the meter operates consistently with the functionality supported by your OpenWay network. For more information about OpenWay network security, see your OpenWay documentation.

The meter’s operation mode can be changed from OpenWay back to ChoiceConnect, if necessary. ChoiceConnect security keys that are in the meter before the transition to OpenWay mode are available if the meter is switched back to ChoiceConnect security.

CENTRON® Bridge Functional Overview 7 Proprietary and Confidential

CENTRON Bridge Meter Operation

Service Switch The CENTRON Bridge meter optional service switch provides utility personnel the ability to turn power off to a customer, turn power on to a customer, and turn power on to a customer with customer intervention.

When the meter is operating in ChoiceConnect mode, Field Collection System (FCS), Field Deployment Manager (FDM), and OpenWay Field-Pro are used to change the service switch state. When the meter is operating in OpenWay mode, the OpenWay Collection Engine or OpenWay Field-Pro is used to change the service switch state. Whether operating in ChoiceConnect or OpenWay mode, the following service switch states are available.

Disconnect. Power is turned off to the site immediately. The relay opens and power is no longer delivered. The meter logs a 'Disconnect Activated' event and displays 'COn OFF'. The disconnect function can be used any time the meter is operating.

Connect. The meter checks for load side voltage. If there is none, the relay closes and power is connected. If load side voltage is detected the meter logs a 'Load Voltage Present' event, displays 'COn LOAd', and the relay is not closed.

Connect with intervention. The meter is armed. The meter logs a 'Connect Relay Initiated' event and displays 'COn rEAdy' until the field input button is pushed. When the field input button is pushed, the relay closes and power is turned on to the site. The meter's service switch status is included in each SCM+ reading that it reports.

To use the service switch operation, the meter must be in the Command Security or Full Security mode so that all service switch commands are encrypted by the Itron Security Manager.

Demand Reset When the meter is operating in either full security or in command security mode, the meter's monthly demand values can be reset remotely in real time. When the meter executes the demand reset, the following demand values are reported:

• Demand reset request status from the meter register

• Date/Time that the demand reset took place

• Date/Time at which the maximum demand read took place

• Demand values collected from the register immediately prior to executing the reset demand

• Maximum demand index

• Cumulative demand

• Continuous cumulative demand

CENTRON Bridge Meter Operation

Tamper and Status Indicators The CENTRON Bridge meter provides tamper and status indicators within the data reads, giving information that can be used to identify potential problems or energy diversion attempts. When operating in ChoiceConnect mode the CENTRON Bridge meter provides the following status messages.

• Magnetic Tamper (single phase only). Indicates the meter has detected the presence of a magnet.

• Removal Tamper Counter. This counter is managed by the CENTRON Bridge meter's communication board and the tamper state must be read at the meter.

• Service Switch Status. Indicates the meter service switch state and allows you to determine if power is available at the meter load or if power has been disconnected from the load side.

• Meter Configuration Counter. Indicates when any meter register configuration change has occurred.

• ChoiceConnect to OpenWay operation mode transition pending. Indicates that the meter has received a request to move from ChoiceConnect mode to OpenWay mode and the transition is pending.

• Reverse Rotation. Indicates the meter has detected a reverse energy event.

• Inversion Tamper Counter. Indicates that the meter assembly has power and has been inverted.

• Loss of Phase. (CENTRON Bridge polyphase only) Indicates when a loss of phase error occurs.

• Non-Fatal Error. Indicates that an issue is detected with the meter that may require some type of action. This error is triggered by Low Battery, Phase Loss, TOU Schedule Error, Reverse Rotation, Mass Memory Error or Register Full Scale Exceeded, and SiteScan Error (polyphase only)

• Fatal Error. Indicates that a critical meter error is detected. Fatal errors can be caused by MCU Flash Error, RAM Error, Data Flash, Metrology Communications Error, EPF Data Error, File System Error, OS Error or FAT 7.

• Register Communication Error. Indicates that an issue is detected with the register communications. Triggered when the communications firmware cannot communicate successfully with the register firmware.

Time of Use (TOU) The Time of Use (TOU) functionality is designed for use in billing applications where multiple rates (bins) are required for energy and demand. The TOU option provides four rates plus the total rate.

TOU Schedules The CENTRON Bridge Meter meter TOU schedule is programmed in the meter up to 24 years at a time. New seasons are sent to the meter via pending tables. The schedule can be changed at any time via the network.

When using the TOU functions of the meter, energy and demand registrations are segmented into time blocks during the day. Each time block is assigned one of four rate periods. In addition to these four rate periods, a total rate is always available.

CENTRON® Bridge Functional Overview 9 Proprietary and Confidential

CENTRON Bridge Meter Operation

Calendar Schedule The CENTRON Bridge Meter meter supports a 24 year calendar. The calendar schedule contains all daily information needed for the meter to measure and register data in real time. The schedule contains daily patterns with configurable day types and rates.

Rates The TOU rates are applied to all energy and demand registers that have been selected for measurement. Therefore, all energy and demand registers are segmented as per the TOU schedule and available in each rate period, in addition to the Total rate.

Daily Patterns Each pattern defines the times during the day that rate period A, B, C, or D begins and ends. Up to six rate period changes may be specified for each daily pattern.

Day Types There are four day types: Weekday, Saturday, Sunday, and Holiday. Each day of the week is assigned to one of the four day types. Each day type is assigned one of the four daily patterns when each season is defined. Any of the daily patterns can be used in any combination with the day types.

Holidays Holidays can be set up either as Fixed or Recurring. Fixed holidays are defined as a single date. Recurring holidays repeat every year. The Recurring Date Type options allow you to determine whether the holiday occurs on the same date every year or moves to another day if the date falls on a Saturday or Sunday.

A maximum of 14 holidays can be set up per season.

Seasonal Schedules A season is a period during the year when a particular rate structure is in effect. Multiple seasons can be set up per year. Only one seasonal TOU calendar can operate within the meter at a time.

Register Capabilities The register can measure numerous energy quantities (as shown in the table below) from which the user can configure up to four to be registered.

If an energy register is edited, the corresponding load profile interval data will be affected.

Load Profile Data Collection and Storage Values The CENTRON Bridge meter collects and stores up to 40 days’ of 15 minute consumption. The following historical usage data is readily available:

• Billing inquiries can quickly and accurately be addressed in real-time.

• Move-in and move-out reads no longer require an off-cycle reading.

• Manually keyed reads can be audited for accuracy without sending field personnel to the service location.

• Two channels of hourly and 15-minute consumption data can be used to facilitate load studies and to enable time-based rates.

You can set up Field Collection System (FCS) to collect load profile values in the following ways:

• Specific date/time reading. Returns a single consumption (historical) reading. It consists of a calculated index reading for a specific date and hour. This is typically used for move-in/move-out readings.

• 40 daily readings. Returns daily consumption readings for a specified hour of the day on each of the last 40 days before the current date.

• 24 hourly intervals. Returns a series of consumption totals recorded during hourly intervals bracketed by 24 calculated hourly readings and ending at a specified date/hour.

• All intervals. Returns the meter’s entire table of data for the previous 40 days of hourly or 15 minute intervals, from the date and time the read is requested.

Manufacturing Requirements CENTRON Bridge meters are built to order and shipped in ChoiceConnect operation mode with command security enabled so the meter requires little or no configuration before installation. When ordering meters, you must provide the following information, which is configured into the meter during manufacturing.

• Meter passwords. Your ANSI C12.18 Protocol security password, which is used for accessing the meter with an optical probe.

• Security Credentials. Because meters arrive with ChoiceConnect command security, your public utility key is required to encrypt the meter security key pairs. These key pairs are then injected into the meter's communication module. Also, for future migration possibilities your OpenWay Shared Key File is also required.

• Meter Configuration. A customer specific meter configuration must be built for each meter type. This includes but is not limited to energy values, demand values, load profile and display formatting.

Supported Software Security

While the meter is operating in ChoiceConnect mode, end-to-end security is provided by Itron Security Manager (ISM) v3.0 interfaced with Field Collection System (FCS) v2.7 or later or with Field Deployment Manager (FDM) v3.6 or later. While the meter is operating in OpenWay mode, security is handled by the ISM.

Workforce Management

When the CENTRON Bridge meter is operating in ChoiceConnect mode, use Field Deployment Manager (FDM) Endpoint Tools Enhanced v3.6 and later versions to change security settings. Use FDM Endpoint Tools Enhanced v3.6 and later versions or OpenWay Field-Pro v3.51 and later versions for maintenance, diagnostics, and reading activities such as operating the service switch, changing configurations, and downloading firmware.

When the meter is operating in OpenWay mode, use OpenWay Field-Pro v2.x and later for maintenance, diagnostics, and reading activities such as operating the service switch, changing configurations, and downloading firmware. Field-Pro can communicate with the meter by means of a ZigBee® radio or through the meter's optical port by means of an optical probe.

Data Collection

While operating in ChoiceConnect mode, Field Collection System (FCS) v2.7 or later is the only meter reading application that supports the all advanced AMR activities of the CENTRON Bridge meter. If you have an earlier version of FCS or an older meter reading application, you must upgrade to a supported FCS version. MV-RS or later also supports reading the SCM+ message.

Customer Information Systems/Billing Systems

Itron’s new SCM+ format supports endpoint IDs up to 10 digits long. The change from 8 digits to 10 digits affects many systems, not just Itron systems. Evaluate all of your organization’s software and database systems that store endpoint IDs for potential effects from the change to SCM+. The first CENTRON Bridge meters are being shipped with 8-digit endpoint IDs, but you should prepare your systems for future 9-digit and 10-digit IDs.

Supported Hardware Collection Devices When operating in ChoiceConnect mode, the meter can be read by a supported meter reading application installed on one of the following devices:

• FC300 handheld computer with Itron radio

• Mobile Collection System (MC3)

• Mobile Collector Lite (MCLite) radio

Supported Software and Hardware

Note While the meter is operating in ChoiceConnect mode, you must use Mobile Collection System (MC3) v3.7 or later or Mobile Collector Lite (MCLite) for mobile data collection.

Evaluate your hardware collection devices and replace unsupported devices as necessary. Not all Mobile Collection systems and MCLite radios support the CENTRON Bridge meter’s two-way capabilities. Verify that the appropriate firmware has been installed on your hardware device to support the SCM+ message format. See the device documentation for further details.

CENTRON® Bridge Functional Overview 14 Proprietary and Confidential

The CENTRON Bridge meter operates securely in either of two modes, ChoiceConnect mode or OpenWay mode. You can switch it from ChoiceConnect operation mode to OpenWay operation mode and, if needed, back to ChoiceConnect mode. The meter operates in one of these two modes at all times, but not both.

From ChoiceConnect to OpenWay Mode Before you switch a CENTRON Bridge meter from ChoiceConnect mode to OpenWay mode, you must have an operational OpenWay network covering the area where the meter is installed. Additionally, your utility must have a complete installation and configuration of OpenWay services, including the OpenWay Collection Engine and the OpenWay security appliance.

Next, determine the date and time you want to perform the transition from ChoiceConnect mode to OpenWay mode. FCS administrators can use FCS application global settings to enable the transition commands and date and time on CENTRON Bridge meters in routes selected by the FCS operator.

FCS includes the mode change commands in route data when the designated meters are sent to the field. This can be done in special routes or as part of normal meter reading route processing. As each meter is processed, the handheld or mobile collector sends the mode change command to the meter along with the date and time for the change to occur.

When the scheduled change date and time occurs, the meter firmware switches from ChoiceConnect to OpenWay mode. The meter ceases to broadcast the SCM+ message, begins transmitting the OpenWay radio protocol to establish communication with OpenWay devices, and starts building the OpenWay mesh network.

Security in the meter changes from the ChoiceConnect security model to the OpenWay security model immediately as the mode transition starts, and if necessary, the OpenWay Collection Engine sends the meter new security keys. If a newer version of the meter firmware exists, use the OpenWay Collection Engine to download the firmware to the meter.

From ChoiceConnect to OpenWay Mode in a Cisco Network When the meter is successfully registered with the OpenWay system in a Cisco network, use the OpenWay Collection Engine to download the Cisco firmware into the meter.

From OpenWay to ChoiceConnect Mode You can switch meter operation from OpenWay mode back to ChoiceConnect mode using OpenWay Field-Pro and either an optical probe or a ZigBee radio to log on to the meter. Once the meter has reverted to ChoiceConnect mode, it ceases to transmit on the OpenWay radio frequency and begins broadcasting the ChoiceConnect SCM+.

Note After you switch the meter to an OpenWay network, if you update meter’s firmware, you can no longer switch the meter back to ChoiceConnect mode.

CENTRON®

Bridge Meter

The CENTRON Bridge meter is the bridge between Itron communication architectures that enable AMI and smart grid functionality. The meter’s adaptability allows it to be incorporated alongside existing Itron electric meters with a mobile collection system, delivering advanced metering benefi ts associated with interval data, remote service switch and demand reset. When prudent for the utility, the CENTRON Bridge can easily migrate to a full smart grid solution, offering demand response and distribution automation benefi ts. With CENTRON Bridge’s versatility and proven operational benefi ts, utilities can address current business challenges and see an immediate return on investment, all while readying for a full smart grid solution as the need develops. Enabled to leverage fi eld assets across two different data collection solutions, a utility can protect and extend its original investment.

The CENTRON Bridge is the fi rst meter to offer compatibility between the OpenWay® network and Itron’s ChoiceConnect® mobile environment. This revolutionary capability is perfect for customers that require advanced metering functionality in a mobile environment today, with complete support for full smart grid functionality in the future.

What does the CENTRON Bridge offer in a mobile environment?

Utilities can deploy the new CENTRON Bridge alongside the existing meter population, reading all meters with the Itron mobile data collection system. This enables the utility to deploy the CENTRON Bridge on a schedule, whether through an annual meter maintenance program, a complete meter replacement or any other combination that suits the business case. With this fl exibility, the utility sets the timetable according to its operational needs, capital management goals or strategic plans.

SPECIFICATIONS

Once deployed, the CENTRON Bridge offers a range of benefi ts. Utilities can streamline current operational processes and subsequently lower costs. Field work required to disconnect meter service is reduced by the ability to activate the under-the-glass service switch in-route with the mobile collection system. Demand reset of commercial meters is also managed with the mobile system, eliminating the need to access the meter or having to worry about setting schedules.

The new CENTRON Bridge also manages and collects up to 40 days of hourly meter data which enable a range of capabilities. With historical usage data, a utility’s customer service department can address bill inquiries in real-time, eliminating the lengthy and costly bill reconciliation process. Customers also gain greater confi dence in the billing process and their bills when questions are answered accurately and in a timely manner.

What does the CENTRON Bridge offer under the OpenWay environment?

While in OpenWay network mode, the meter is fully compliant with the ANSI C12.19 and C12.22 standards for storage and transport of register data. The CENTRON Bridge provides a secure and reliable open-standards approach to data collection and communications between the meter and network.

In addition, each CENTRON Bridge comes factory-equipped with a ZigBee® radio chip to provide a built-in communications pathway into the home for data presentation, load control and demand response. ZigBee also provides a communication channel with 2.4GZ OpenWay gas modules. ZigBee communications can be available regardless of whether the meter is in OpenWay or mobile mode.

The CENTRON Bridge also provides robust data storage capability to support time-of-use pricing, multiple-channel load profi le data and other data-intensive applications, as well as the most advanced feature set available to support smart grid requirements. These features include full two-way communication, a load-limiting remote disconnect and reconnect switch, positive outage detection and restoration notifi cation, voltage monitoring, automatic tamper and theft detection, as well as the ability to reprogram the meter remotely and upload new fi rmware via the network.
