IEC 62056-21 “Flag”

Introduction

IEC 62056-21 is the third edition of the well-known IEC 1107 standard, also known as the “Flag protocol”. Although it was intended for local data exchange using hand held units (HHU), it is also widely used for remote data exchange with PSTN and GSM modems.It specifies three local physical interfaces: optical, current loop and V.24 / V.28, as well as a data transmission protocol. The protocol permits reading and programming of devices, basically by reading and sending information represented by ASCII characters to / from given memory locations.

Like 1107 ,the following communication modes are available:

• Mode A supports bi-directional data exchange at 300 baud without baud rate switching. This protocol mode permits data readout and programming with optional password protection;

• Mode B supports bi-directional data exchange with baud rate switching. This protocol mode permits data readout and programming with optional password protection;

• Mode C supports bi-directional data exchange with baud rate switching and permits data readout, programming with enhanced security and manufacturer-specific modes;

• Mode D supports unidirectional data exchange at a fixed baud rate of 2400 baud and permits data readout only;

• Mode E supports advanced protocols, like DLMS/COSEM.

The mode can be negotiated by the HHU and the meter. A meter can support more than one mode: today, support of Mode C and Mode E with DLMS/COSEM is common practice.

Status of standardization

The current standard has been established by IEC 62056-21 WG 14:. IEC 62056-21 Ed. 1.0:2002, Electricity metering – Data exchange for meter reading, tariff and load control – Part 21: Direct local data exchange (third edition of IEC 61107) The standard is open and widely used. However, the memory mapping is not standardized, therefore data exchange requires manufacturer specific information. Meters of different types or from different manufacturers are not readily inter-operable: each meter type needs a specific driver. Annex C of the standard specifies formatted codes, but these are not widely used.

Support organization

The mandatory three-letter manufacturer identifiers are allocated by the FLAG Association, in co-operation with the DLMS User Association. The same identifiers are also used for DLMS/COSEM. Some three hundred manufacturers have obtained their manufacturer ID.

See at: http://www.dlms.com/organization/flagmanufacturesids/index.html

Data model

Not available in modes A to D, data are located and manufacturer specific memory addresses. In Mode E, the COSEM data model and protocol stacks are used.

Communication media supported

The current loop is a local bus supporting up to eight meters. PSTN and GSM are supported with appropriate modems.

Summary

This protocol was the first standard protocol for meter data exchange and is globally used.

Today, its main use is for local data exchange.

IEC1107 Sample Output From the Meter-IEC1107 File Format

The Optical Port Reader IEC1107 is a device enabling communication between any type of electricity meter equipped with a port according to the IEC1107 standard and a reading device equipped with RS232 or USB 2.0 port.The data read from meter will in the form of a file similar to following. But the standard does not specified more about the format and length of data and most of those are manufacture specific.
But it defines that data should be :
V(00 +00.00 08 00 +00.00 08 00 +00.00 08 00 +00.00 08 ) in this format. where V specifies the type of data in that line.

Manual Reading of IEC1107 meter

The optical read-out head is used for data communication between a PC or hand-held terminal to energy meters, electricity meters and similar metering equipment with optical data port according to IEC 1107/EN 61107(according to the IEC1107 standard and a reading device equipped with RS232 or USB 2.0 port.). Applications range from simple data readings e.g. for billing purposes and comprehensive programming of meters.
An application("IEC1107 testing software Test1107pack.exe") from http://www.meter-test-equipment.com/index.php?page=download&lng=en can be used for reading data from meter supporting IEC1107 protocol.

Meter with optical port

Connect the cable's optical 'port end to the meter and RS232 DB9 cable to the PC. Through a any serial port emulator or Hyper terminal in windows, enter the command according to IEC1107 protocol to read the meter data, most probably which may contains the historical data. But unfortunately the data or meter file read from different meters were different for different manufactures and make.

/?!<0D><0A> could be the first command for initiate the data read.

Then meter will respond with identification response and it may like ,

/LTA4L0506272

After that we have to give a command to read meter file an that may be like

<06>040<0D><0A>

After that we will receive a series of characters which collectively forms the the historical reading of the mater.

HHU(Hand held unit) for reading meter data

Some meters like LnT 's ERP300 comes with rs485 port that support IEC1107 protocol ,in that case command needs a device address to read the meter. Which supports multidroping and all.
