Do these meters need a meter Prrotocol in the sign on? Via terminals or suitable connectors. The hardware of a two-way optical interface is described; its mechanical and optical parameters.
Both prootocol standard baud rates. Top Almost certainly not! If you want more info please call me. Initial baud rate — I think it is a shame; they do not bother to educate their customers.
This interface is still used on some U. It may be purchase from ANSI’s offices or online.
IEC Electricity Meter Interface | Elektor Magazine
The mode being used by the tariff device is indicated by the baud rate identification character in the identification message from the tariff device. Standard baud rates —, 1 ,249 Select the categories for which you would like to see messages displayed Please read those terms and conditions carefully. Choosing IC with EN signal 2. 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.
This meter has a IEC optical interface. IEC always starts at for electricity meters and then prootocol negotiate a faster rate.
Top Intelligent tariff meters that have IEC optical interfaces also have a numeric display and so can be read normally.
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.
Distorted Sine output from Transformer 8. Alternative online sites for purchasing and downloading this International Standard include: Intelligent tariff meters that have IEC optical interfaces also have a numeric display and so can be read normally. The hand held unit then sends a sign-off message.
In case of high security parameters,the meter challenges the hand held unit with a cryptographic password. How do orotocol get an MCU design to market quickly? By Gilles Allard on 6 December, – 9: Top Probably but not necessarily. Digital multimeter appears to have measured voltages lower than expected.
How to read data from IEC Energy Meter – happily embedded
Watch an animation of a conveyor stacking operation demonstrating the use of a move on a gear command. If the parameter required is in low security group, a password authentication of the HHU is required before information can be read. I know that iwc1107 remote is sending irda frames not ordinary asynchronous ascii characters, and is working at a different IR frequency than the IEC sensor. PNP transistor not working 2.
The physical media are usually either modulated light, sent with an LED and received with a photodiodeor a pair of wires, usually modulated by a 20mA current loop. Search for the current document: Turn on power triac – proposed circuit analysis 0. If no sign-off message is sent, the meter automatically signs off after a previously negotiated time interval after the last message.
It looks like an IEC port – is it? Heat sinks, Part 2: Data exchange for meter reading, tariff and load control.
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! Power consumption would also increase.
IEC1107 Electricity Meter Interface
If you’re not already a member, consider joining. After signing on, the hand held unit generally reads a meter prptocol. Contents What is IEC? The IrDA device would not offer any shielding and so data errors are more likely. This page was last edited on 24 Januaryat Both use half-duplex communication.
These probes are sold on ebay http: Direct local data exchange” The document may also be published by the Standards Organisations of other countries. Robert, These probes are sold on ebay http: The document title is: How reliable is it? The software specification includes data rates, character format and transmission protocol. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7.
