This simple project describes a neat IEC to RS interface that a specification IEC that defines a software communication protocol and the. Does anyone have information about the protocol IEC ? Why do some vendors talk about protocol IEC and some about IEC I have a British Gas installed Landis+Gyr E smart meter. This meter has a IEC optical interface. I am experimenting with an.

Sorry, Ivan, I am Ivan as well. I suggest you try them. Use British English Oxford spelling from December Input port and input output port declaration in top module 2. Probably but not necessarily. The meter and hand-held unit negotiate various parameters such as the maximum frame length during transmission and reception, whether multiple frames can be sent without acknowledging individual frames windowingthe fastest communication iex1107 that they can both manage only in case of mode E switching to HDLC etc.

Protocol IEC for metering

Remember me on this computer. Your question is easily answered: The IEC standard has been adopted by meter manufacturers throughout Europe and in some other territories. Next the meter informs the hand held unit about the various parameters that are available with it in various security settings viz.


Does anyone know some vendors which have systems in Europe.

If you want more info please call me. The document title is: Robert, These probes are sold on ebay http: You must be a Control.

IEC1107 Electricity Meter Interface

protocpl By Darshan Shah on 25 May, – Is it same with Has anyone managed to get anything back from one of these meters? The mode being used by the tariff device is indicated by the baud rate identification character isc1107 the identification message from the tariff device. Both use standard baud rates. Can I read my own meter? PNP transistor not working 2. The attributes and methods constitute an object. If the parameter required is in no security group, just a get. This Standard describes the software protocols and hardware for exchanging data with utility tariff meters.

The protlcol of a two-way optical interface is described; its mechanical and optical parameters. Please log in and try again. Top Probably but not necessarily.

This protocol mode permits data readout and programming with optional password protection. These modes are usually protected by anti-tampering features such as switches that sense if the meter enclosure has been opened.


I think it is a shame; they do not bother to educate their customers. This interface is still used on some U.

To read a meter electronically through its optical port requires suitable software. The IrDA device would not offer any protoco, and so data errors are more likely. Ultrasonic E6 gas meters manufactured by Sensus Invensys-Eurometers-Equimeter and Actaris Schlumberger employ an optical port as described in the IEC document but the software protocol differs.

These probes are sold on ebay http: A meter can support more than one.


Wall Robert Wall Digital multimeter appears to have measured voltages lower than expected. In addition, Mode C allows for programming of the tariff device.

If the parameter required protoocol in low security group, a password authentication of the HHU is required before information can be read. Output levels and sensitivities are broadly compatible but are specified differently. All modes offer the provision of automatic data readout.
