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.

The general protocol consists of a “sign on” sequence, in which a handheld unit identifies itself to the metering unit.

Top Almost certainly not!

IEC1107 Electricity Meter Interface

However if I connect up the send side and run my test program which sends the init command every few seconds and I press the remote I see something else going on, weird! It is one part of the identification of the object. This interface is still used on some U. I connected oscilloscope to the receive side of the sensor. Ice1107 manufacturers, continue to refer to IEC rather than the newer prrotocol less-memorable document number. This Standard describes the software protocols and hardware for exchanging data with utility tariff meters.

List of International Electrotechnical Commission standards. Even manufacturers continue to claim to be IEC compliant.

The Blue book describes the COSEM meter object model and the OBIS object identification system, the Green book describes the Architecture and Protocols, the Yellow book treats all the questions concerning conformance testing, the White book contains the glossary of terms. PNP transistor not working 2. I was thinking of using lirc to test the RX side of the probe. Both use half-duplex communication. There are plenti of systems for DLC – e.


Or of course it also means the rx side is fried. Entitled users will be able to obtain software from the meter manufacturer or from vendors of meter reading systems. Most metering units have special modes for calibration and resetting meter registers. IEC or currently IECwas an international standard for a computer protocol to read utility meters.

Could you use any remote control to check the receiving side for signs of life? I am struggling to get complete IEC protocol document. For reasons of security the optical probe system is closed after the point of manufacture.

After signing on, the hand held unit generally reads a meter description. Like most Standards, the IEC document is copyright and can not be reproduced here. Thus the standard created as is now Contents What protoco IEC?

Next the meter informs the hand held unit about the various parameters that are available with it in various security settings viz. By using this site, you agree to the Terms of Use and Privacy Policy. The protocol is usually half-duplex.

ABACUS ELECTRICS – IEC – What is it all about ?

Australian Standard AS The software specification includes data rates, character format and transmission protocol. I suggest you try them. From Wikipedia, the free encyclopedia. But nothing when I just shine a tv remote into it.


But I agree with you I have probably fried the receive side of the sensor. Hi Ivan from Chile! To search the site, enter your search terms in the box labeled “search the site” and hit Enter. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7. Distorted Sine output from Transformer 8. Any real world thing mapped to an appropriate class type can be described by the attributes defined in the standard; and the methods defined therewith allow operations to be performed on the attributes.

If you’re not already a member, consider joining. Regards, Carlos Araya Mackenney [caraya cmet. Because this pcb was on the other end of a meter of cable from the actual sensor I initially assumed that the markings were relative to the cable end not the device.
