Hi everybody,

I am new to cosem, and I want to read information from ISKRA ME 172 using cosem protocol, but I found this protocol very difficult. I don't know from where I should start.
Could you help me?

Thanks,

Hi,

ISKRA ME 172 is not supporting DLMS. It supports IEC 62054-21.
IEC 62054-21 is ASCII based protocol and it's easier to use.

Hi,
Thank you for your answer Kurumi, I want to know about ISKRA MT880, is it working with dlms or with the same protocol IEC 62054-21?
Thanks,

Hi,

ISKRA MT880 is using DLMS. You can use GXDLMSDirector to read it.

Hi,

Iskra ME 172 is not supporting DLMS. It's using IEC 62054-21 also know as IEC 1107.
IEC 62054-21 is ASCII protocol and It's easier. Problem is that there are lots of variations between different meters. If you do not need anything special you can try to get readout from the meter.
(I'm not sure is this meter supporting it, but you can try).

Set serial port baudrate to 300 and Data bits: 7, Parity: Even and StopBits: 1.
Then send /?!r\n to the port. Meter should response and send some information.
If you wait more usually Mode A is used and meter send readout.

Hi,

I want to communicate with the ISKRA ME 172 via RS 485, I have written a code respecting the IEC 1107 protocol, but I haven't got any answer.

Thanks.

Hi,

Try to change baudrate to 4800 or 9600. Then try to change settings from 7E1 to 8N1.
Are you using optical strobe or serial port connection?

Hi,

Thank you Mikko for your reply, I have tried all baudrates possible in the protocol. I am using RS485.

Thanks.

Meet the same problem. RS-485
Tried baudrates 300, 4800, 9600 (Representative sad this is default). Tried 8N1, 7E1.

None of them worked.
