Hello,
Is there a way to find OBIS code from a ReadRequest trace?
For example this HDLC frame: 7E A0 11 03 41 FE 82 54 E6 E6 00 05 01 02 9A F0 8A 80 7E
means a readRequest for OBIS code 1.1.32.7.0.255
GURUX DLMS translator returns this:
<HDLC len="10" >
<TargetAddress Value="1" />
<SourceAddress Value="20" />
<FrameType Value="FE" />
<PDU>
<ReadRequest Qty="01" >
<VariableName Value="9AF0" />

Those who limited to DLMS Color books (BLUE, GREEN, YELLOW and WHITE) can discuss and enhance knowledge on DLMS/COSEM standard code IEC 62056 series

Hello!

I'm trying to read out data from an Iskraemeco AM550 using the IR interface via the Gurux python interface (on Raspberry PI). I followed the setup instructions but so far I'm unable to receive any data from the device:

Hello,

I would like to create a DLMS client with gurux_dlms python library.I have already downloaded the source code on Github but i don't know how to use it.
Could I have some help please.

int CGXDLMSClient::ParseApplicationAssociationResponse(
CGXByteBuffer& reply)

at last I think should set

m_Settings.SetConnected((DLMS_CONNECTION_STATE) (m_Settings.GetConnected() | DLMS_CONNECTION_STATE_DLMS));

befor
equals = challenge.Compare(value.byteArr, value.GetSize());

hi,

when trying to read from Landis gyr e550 using python shows data send failed error

command used python3 main.py -S /dev/ttyS2 -i

output get

Good morning to all

I am working on a project with DLMS/COSEM meters and security suites. If I have a meter that supports Suite 2, can I use the gurux client to establish communication using Suite 0 with static EK keys, even though the size of the keys between both suites is different?

Thank you for your kind reply

Hello,
Can you please provide example how to read data via plc protocol with .NET library? I guess i need to initialize GXPlcSettings with correct parameters. I know that plc configured with key 1441 in the meters and the modem is IT900.

Hello

I'm trying to read EDMI ATLAS MK7MI using RS-232 port. Information from brochure this meter using DLMS IEC62056 protocol in all ports including RS-232. But other EDMI ATLAS line up using 'EDMI Command Line' ex. MK10E which i can understand this protocol.

My Question is, what protocol is used by MK7MI in RS-232 port. And what steps to connect meter using DLMS protocol with Gurux DLMS Director via RS-232 port.

Thanks.

If we join club, do you have any other code about suit1 for c++ ?
