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.

Asslam Alicom Ivan for information about go to www. F erranti and L andis A nd G yre were early proponents of an interface standard that eventually became a sub-set of IEC I did initially connect the rx and tx the wrong way round due to poor documentation.

Top Probably but not necessarily. By Meir Saggie on 18 February, – 4: The hand held unit must return an encrypted password.

This page was last edited on 24 Januaryat But I agree with you I have probably fried the receive side of the sensor. Your question is easily answered: In which the hand-held unit HHU is connected to one tariff device only at a time.

C source code for the implementation of IEC on the MCU

Australian Standard AS You have clicked on the “? I am struggling to get complete IEC protocol document. The general protocol consists of a ptotocol on” sequence, in which a handheld unit identifies itself to the metering unit. During sign-on, the handheld unit addresses a particular meter by number.


IEC1107 Electricity Meter Interface

Here are a few observations concerning the possible use of devices with IrDA ports communicating with protoco meters fitted with IEC ports. Retrieved from ” https: It’s free, and you can customize the content you view, as well as being able to subscribe to threads and topics, getting new posts delivered to your email as they appear.

IEC communication can be slow with older meters that do not step-up the baud rate. It is easy to protkcol we have same drivers.

Both use half-duplex communication. The operator would have to hold the IrDA device steadily in mid-air for some time. So either the meter is not responding or the RX side of the probe is fried.

Digital multimeter appears to have measured voltages lower than expected. If the password exchange is ok, the meter accepts the hand held unit- it is “signed on. Some tips for better search results Use British English Oxford spelling from December Have you been able to find something useful.

I know that the remote is sending irda frames not ordinary asynchronous ascii characters, and is working at a different IR frequency than the IEC sensor. IEC uses a symmetrical mark-space ratio; in order to achieve long range with low power IrDA does not.


ABACUS ELECTRICS – IEC – What is it all about ?

An IEC probe fits over the port on the meter and shields the meter sensor from stray light. Any real world thing mapped to an appropriate class type can uec1107 described by the attributes defined in the standard; and the methods defined therewith allow operations to be performed on the attributes. By Kerem Ozdemir on 7 May, – 3: Communication in mode D is uni-directional. Next the meter informs the hand held unit about the various parameters that are protocoll with it in various security settings viz.

Because this pcb was on the other end of a meter of cable from the protocil sensor I initially assumed that the markings were relative to the cable end not the device. Special baud rate – as desired.
