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

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.

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.

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.

7.0 Time Of Use
7.1.1 Overview
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）.

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.
