Hi,

Am working in metering , task assigned to me learn DLMS protocol, I read books,
Now I want to learn DLMS meter data download, I have DLMS meter , I want to read it on serial port,

I have down loaded DLMS.net

1) Development
2) Gurux.DLMS.Client.Example.Net

Gurux DLMS .net I found one setting.cs Class and main program class,

Please send me some working code for program class settings,

I tried severl ways ,but no example code i find is working.

Please send me setting for read meter on serial port.

Dear Gurux,

I am getting "AARQRequest failed Rejected permament and No reason Given" Error while establishing a connection between Meter. I try the same Authentication key, password etc in gurux director its working fine but in Gurux ANSCI C Client code getting this error.

Hello MikKo,
I would like to use the Gurux DLMS XMLClient.
(located at \Gurux.DLMS.Net-master\Gurux.DLMS.Net-master\Gurux.DLMS.XmlClient)

If I undestood well, I need to install the visual studio in order to generate the .exe file. isnt´t it?
The version that I have is the Microsoft Visual Studio Community 2019 Version 16.11.6

Hello,

I am using gurux.cpp library. I would like to know if it's possible to get information about the specific object (specified by LN only) without calling getAssocationView (which retrieves all objects).

For example:

CGXDLMSObject myObject("1.0.1.4.1.255");

Read(myObject); // finds that this LN is Demand register and reads values

Or atleast like this:

CGXDLMSObject myObject(DLMS_OBJECT_TYPE_DEMAND_REGISTER, "1.0.1.4.1.255");

Read(myObject); // it's already known that is demand register and reads values

Hi
You have earlier had contact with Christer during development of suite1 for Sanxing meters. We have now deployed some of what we have done and see a big increase in CPU load on the machines. Could there be any issues in Gurux regarding this or do you think this is as expected?

I attach some screenshots of CPU load when running in suite0 and suite1(HLS7)

Hi, Mikko!

I found bug into GXDLMSObjectCollection.load() method
Deserialization of Item
<GXDLMSData>
<Value Type="3">0</Value>
</GXDLMSData>
return object_data.value=True

At method GXDLMSConverter.changeType() instead
ret = bool(value)
should fix on
ret = bool(int(value))

Dear Sir,

How i can able to write the bit string any example code do you have ?

I'm having the problem with both python and GXDLMSDirector.
I've a secured meter over a Wrapped TCP connection. Using GXDLMSDirector, I've introduced the meter keys and connected correctly. The problem is that as soon as I try to read an object or if I try to disconnect I get an error.
With the release it will give me back a not finished error (APDU 63 reason 1.
With the reading (a load profile) it will be an scope error.

hi Sir
If we use this
#ifdef DLMS_IGNORE_MALLOC
#define GX_OCTET_STRING(X, VALUE_, SIZE_) GX_UNION2(&X, pVal = VALUE_, (DLMS_DATA_TYPE) (DLMS_DATA_TYPE_BYREF | DLMS_DATA_TYPE_OCTET_STRING), SIZE_, sizeof(VALUE_))

, we have to comment #define DLMS_IGNORE_MALLOC , but you said it does not need to be used on the server؟

void GXDLMSServer::assingBlockCipherKey(dlmsVARIANT* value)
{
GX_OCTET_STRING(*value, settings.base.cipher.blockCipherKey, 16);
}
