1.0 Foreword

MeterBuddy 2.2, The Program Tool of Libra Meter, obey ANSI C12.18-1996 ,C12.19-

1997 .

The software is used to debug, test, read and program the Libra Meter. This is a full

version which includes all function. When it is provided to end-user, we will publish

a simple version which incluses basic function.

This document applies to the implementation of an ANSI C12.19 Standard Sub Set

inLIBRA_WASION _Meter AMR Test tool - MeterBuddy.

(LIBRA_WASION_Meter is an upgrade version of the Libra Meter, Designed for LIBRA

IEC Meter Project, so the MeterBuddy can be used to Test LibraI , LibraII and Libra III)

In the extend view, click [Discover] button to discover sub-net (include Zigbee Mesh

network) and list all of the device.

When the [Discover] button is clicked, this application will transmit a broadcast UDP

packet containing the message –“Discovery: Who is out there?” on the local network

to port 30303. Any Libra meters which include LibraDigiEth module and connect to

the network, they will respond with a UDP packet containing their host name and

MAC address.

Double click a IP Address then copy it to IP input box. Caution: this function can

only discover the Libra device in the same subnet of computer.

Click [Read Meter ID] button to read the meter’s Identification according to the IP

Address.

After you complete the parameter setting and password inputing, Click [Start]

button to continue.

The menu [Meter] will be enabled.

Because the BaudRate of two kinds of ports are different, so you should make some

changes as below.

1) Remote or Local IR

2) PLC Port (UART port of AMR/AMI module)

Other Settings:

Libra-1,3 seris can only support Local Optical Port, Libra-2 seris can support

both Local and Remote Optical port. You should select the optical type before

you connect MeterBuddy to meter.



Issue/Rev. 2.85 Date 08/10/2012

When you use Remote Optical Port or RS485 connect to meter, you should set

the meters Address here.

The Address is the last two digits of the meter ID which is printed on the

Nameplate of meter.

When you connect to a meter (include LibraDigiEth card) via Ethernet (or Ethernet

+ Zigbee Mesh Network), you should input the meter’s IP Address and TCP port.

ANSI C12.18-1996, Type2 Optical Port standard. The protocol is used for Local

or Remote optical port, and can be used for Ethernet communication too when

LibraDigiEth works as a Ethernet Extender.

6.5.1.1 Demand setting parameters.

This table is used to set demand working parameters. The meaning of parameter

dictated by ANSI C12.19 Table 13- Demand Control Table. Demand Control, is used

to specify information affecting demand, such as interval size, reset exclusion, etc.

Notes: If no special requirements , the above four parameters, generally do not need

to set. If the meter to detect the error about parameters of the demand , it will

initialize the parameters to default values. the default value is 0.

Sub_Int, for Sliding demand, the value of minutes in the sub-interval. The value

is set from 1 to 15.

Int_Multiplier, for Sliding demand, minutes of multiplier.

Valid Demand Interval Length/Interval Multiplier Combinations

The valid interval lengths appear in the first column; interval multipliers are

listed across the top row. The intersection of any row/column will show a valid

subinterval size or '√' to indicate that the combination is supported.

MeterBuddy supports to program Time Of Use(TOU), such as Real Time Clock,TOU

Control,Non-Recurring Calendar, Fixed-Recurring Calendar and Schedule. This

chapter takes several examples to discribe that how to program TOU.

The maximum total number of dates supported is 32, distributed between

recurring and non-recurring dates as desired. The meter require that the dates

be sorted(Small to large)

Tier switches must be sorted. Tiers must be grouped by daily schedule ID's and

sorted by time within each ID group.

TOU support maximum : 8 non-recurring dates, 32 recurring dates, 64 tier

switches( each DAILY_SCHEDULE_ID_MATRIX include 4 schedule tiers ),4

changed seasons, 4 day-type, 1 special schedule, 4 schedule

tiers(PEAK,BASE,REDUCE,VALLEY）.

10.0 Load Profile

The reader/programmer will be able to initialize load profile memory or disable load

main board.

support 4MB Card which value can not be modified.

LP data is transported in the format dictated by ANSI C12.19.

Number of Data Blocks and Sectors can be set

Days in accordance with the order as a unit of data sub- blocks , each block

contains a block header and many sectors . The maximum number of sectors

can be set in which the block header contains a time data and a block read data

LP Data stores by the day , every day is stored as a data block. 0:00 daily

branch for block storage. The size of the data stored in each block is generated

automatically based on setting parameters .

The relationship between capacity and load profile interval length can be

calculated with Load Profile Data Set1 Table which can be referred Table 64

10.2 LP Settings Parameters

This table is used to set Load Profile .

Memory Card Length(Bytes), Libra-3 meter support 4MB Card which value can

not be modified.

Number of Days, the value is calculated automatically .

Libra-3L meter optional recorder is capable of handling 42 days of 15 minute

load profile data on four channels with 32K or 42 days of 15-minute load profile

data on 15 channels with 128K bytes of memory. The number of days of

capacity is dependent upon the interval length duration and the number of

channels used.

Number of Intervals per day , max intervals based on interval length, the

value is calculated automatically .

Number of Channels, 1~16channels can be set.

Interval lengths , Load Profile interval lengths include, 1, 5, 15, 30 and 60

minutes. Each interval consists of two bytes.

The register records up to 15 channels of load profile data. The number of

channels is programmable. The available memory is distributed equally among

each channel.
