Hi,

Im using python 3.8 with:
code: Gurux.DLMS.Python/Gurux.DLMS.Client.Example.python
gurux_dlms version: 1.0.74
gurux_net version: 1.0.17
gurux_serial version: 1.0.14

i am able to read a meter by serial port, but when i tried to save the xml data of the meter with the next command:
E:main.py -S COM2 -c 1 -s 145 -a Low -P 12345678 -C None -g "1.0.32.7.0.255:2" -o c:\device.xml -t Verbose
i got this error:

Hi Mikko,

I have gone through the blue book. In that methods are available for the following DLMS objects:
Demand Register : Reset
Extended Register : Reset.

I have checked in Register DLMS object. In that reset method available. So can you please add the same method in above defined DLMS objects,

Thanks

Hie Mikko.

Thank you for your Python DLMS library it has really helped me understand the DLMS protocol.

I have been connecting to my Landis & Gyr E460S meter using default settings (Client Address 16 with no password connection) and I have been getting the following Read-Write errors:

-------- Reading 70 0.0.96.3.10.255 Ch. 0 Disconnect control
Index: 1 Value: 0.0.96.3.10.255
Index: 2 Value: True
Index: 3 Value: 1
Error! Index: 4 Access Error : Device reports Read-Write denied.
Access Error : Device reports Read-Write denied.

Hi
How are you ?

Is there a way to convert "wrapper" packets to "hdlc" packets?
Please help me.

Hi Mikko,

Whenever I read nameplate profile object. Before read function I set SetUIDataType DLMS_DATA_TYPE_STRING then read object. But I get data buffer in octal instead of string format.

How should I read namelate profile object in readable format without apply conversion?

Kindly find the blow mentioned sample code-

Hello!
When reading objects of the Generic Profile type, a memory leak of about 1 kB occurs as a result of the "com_readProfileGenericColumns" function. This leak is not fixed after calling the functions "com_readValues" and "com_readProfileGenerics". How and where can I free up occupied memory?

I reading from meter 15 attribute Account and use for it function from GXDLMSReader is ReadDLMSPacket, but in result i have exception Invalid data type.
When i read info from object Account in GXDLMSDirector, then i have exception too.
In GXDLMSDirector on tab Access rights 15 attribute is AccountClosureTime, but 15 attribute in DLMS Blue Book 12th edition for object Account is Structure Currency. This error or not? And if this error, then it's will be repaired?

Hello,
I found some mistakes when trying to compile this commit.
668a488cb84bfc7cdd22dc554650f12d31b1c2a2 in https://github.com/Gurux/Gurux.DLMS.cpp.git repo

-in file GuruxDLMSClientExample/src/GuruxDLMSClientExample.cpp line 488, i replaced with
sprintf(buff, "Unknown object: %s", str.c_str());

I get response from meter classId (example: 3) and LogicalName. How i may create new object with need objectType (example GXDLMSRegister)? This constructor for GXDLMSObject is protected.

Hi! I use HDLC to communicate with the counter. Here is the answer from the counter:
7E A0 18 C9 00 02 FE FF B8 1E D4 E6 E7 00 C4 01 81 00 06 00 02 2F 32 A9 D8 7E
The answer shows that the data from the counter 06 00 02 2F 32
It means:
06 - Unsigned32
00 02 2F 32 - the number 143154.
But the GXReplyData.Data.Data property returns 06 00 02 2F 32 00 02 2F 32, instead of 06 00 02 2F 32. The last four bytes were copied to the end of the response. How to avoid this?
