PROBLEMS

• Protocol

No common, Standard / open protocol

is available in the energy meters available nor themeters which are being purchased.

Standard Protocol :-

•  PACT (Multi dropping not possible)

Open Protocol :-•  Modbus ( Values are integers have to use

multiplying factor at software end)

•  IEC 101 (No known meter available)

PROBLEMS

• Communication Port

No common type of port is available in the

energy meters available nor the meters which arebeing purchased.

The mixture of Optical, RS-232 and RS-485 isavailable and none has the record of the ports.

Recommended :-

RS-232 for the meters installed individually

RS-485 for the meters installed in groups(Substation, Group Metering)

PROBLEMS

• Existing Meters

As these meters vary in technologies, makes,

Protocols, communication ports, etc. which createsa difficult situation for AMR implementation teams.

Recommended :-

Request the manufacturer to take back old metersand replace with new ones, as in many a cases it is

only firmware up-gradation or minor modification.

PROBLEMS

• Technology

As these meters vary in technologies, makes,

protocols, communication ports, etc. which createsa difficult situation for AMR implementation teams.

Recommended :-

Request the reshuffle / change energy meters tocreate the situation for the AMR supplier to opt. one

technology / methodology for the system.

Example : Change all substation meters with theones having RS-485 port & Modbus protocol.

PROBLEMS

• Implementation Time

As these meters vary in technologies, makes,

protocols, communication ports, Multiplying factorsetc. which creates a difficult situation for AMRimplementation teams.

Recommended :-

Request the reshuffle / change energy meters to

create the situation for the AMR supplier to opt. onetechnology / methodology for the system.

This will reduce the AMR implementation timedrastically.
