Manufacturers identification The Manufacturers identification consists of three upper case letters except the third letter, it can alsobe transmitted as a lower case letter. If the third letter is a lower case letter, that means that the tariffdevice has a minimum reaction time of 20ms instead of 200ms. If the device transmits only upper caseletters it does not preclude that it does not support 20ms. ( see <FLAG : Registered Manufacturers Identification Characters> )

Baudrate identification The Baud rate identification is used for the baud rate changeover. The "request message", the"identification" and the "acknowledgement/option" are transmitted with an initial rate of 300 Bd ( not validfor protocol mode D ). The baud rate identification in the message is determined by the used protocolmode.

Protocol mode A :No baud rate changeover is provided for this mode. Each character is allowed, excepted are thecharacters "/", "!" and the character may not be specified as baud rate for protocol mode B or C.

Protocol mode B with baud rate changeover :In this mode the "acknowledgement/option" is not used.A - 600 BdB - 1200 BdC - 2400 BdD - 4800 BdE - 9600 BdF - 19200 BdG, H and I are reserved.

Identification of data sets ( address/ identification number )

For a clear identification of the values ( active power, reactive power, ... ) the "Object Identification System" ( OBIS ) is used.

Detailed informationen to the OBIS numbering systematization you will find in the IEC Standard Documentation<IEC 62056-61 : Electricity metering - Data exchange for meter reading – Part 61 : Object identification system ( OBIS )>

and ( only in German language available ) in the

<VDEW-Lastenheft "Elektronische Lastgangzähler">Version 2.1.2 / 07. 11. 2003

OBIS has replaced the draft standard EDIS ( DIN 43863-3:1997 EDIS - Energie Data Identification System ) and defines the usual identifictionnumbers for metering systems and data transmissions.

A OBIS code consists of six value groups which are described in the following section with A... F and characterizes the data value.


10 of 13 9/21/2010 9:48 AM

The value of group C indicates the direction of the energy flow.

The tariffs are indicated by sequential numbers. If the value is tariff independent the data are transmitted with tariff code number "1". For valuesthat are registered in several tariff numbers the tariff counter is indicated by the tariff code number "0". The tariff number 0 is also used for nottariff-distinguished load profiles.

The value group F ( pre-value identifier ) is only used for the transmission of pre-values.

Vereinbarungen im OBIS erlauben die Definition von landesspezifischen OBIS-Kennzahlen. Die Festlegung dieses Kennzahlenbereichs erfolgtüber die Wertgruppen "C" und "D", wobei "C" den festen Wert 94 und "D" zur landesspezifischen Unterscheidung eine Landeskennzahl inAnlehnung an die Telefonvorwahl des Landes enthält. Die Werte für die Wertgruppen "E" und "F" können nun länderweise frei belegt werden. DieWerte für "A" und "B" haben weiterhin die per OBIS vorgegebene Bedeutung.
