Hello everyone,
sorry if this might sound dumb, i'm taking my first steps into DLMS and with this library in particular.
I'm trying to read some informations from my meter device, but while coding my simple app i'm figuring out i cant find a way to set some specific values.
here is how, for instance, i'm reading the LDN.
GXDLMSData ldn = new GXDLMSData("0.0.42.0.0.255");
DataType dt = DataType.OctetString;
ldn.SetDataType(2, dt);
reader.Read(ldn, 2);
where reader is an instance of GXDLMSReader
this generatess an APDU that is correctly understhood by my meter:
C0 01 C1 00 01 00 00 2A 00 00 FF 02 00
which translates in the XML:
<GetRequest>
<GetRequestNormal>
<InvokeIdAndPriority Value="C1" />
<AttributeDescriptor>
<!--DATA-->
<ClassId Value="0001" />
<!--0.0.42.0.0.255-->
<InstanceId Value="00002A0000FF" />
<AttributeId Value="02" />
</AttributeDescriptor>
</GetRequestNormal>
</GetRequest>
the problem is when i have to read something that has a different classID and possibly attributeID values.
how do i create, from code, a PDU like this?
C0 01 C1 00 44 00 00 19 04 00 FF 05 00
this is derived from the following XML
<GetRequest>
<GetRequestNormal>
<InvokeIdAndPriority Value="C1" />
<AttributeDescriptor>
<!--DATA-->
<ClassId Value="44" />
<!--0.0.25.3.0.255-->
<InstanceId Value="0000190400FF" />
<AttributeId Value="05" />
</AttributeDescriptor>
</GetRequestNormal>
</GetRequest>
thanks for your kind reply.
Also: is there any example of using Gurux DLMS to perform a SET request?
integrating actaris Meter getting Issue.
i got stuck at get profile generic coloumns...
what might be the reason.
app got hangged cant able to view the logs even.

Hi Swappage,
Hi Swappage,
What programming language you want to use? If you are planning to parse bytes by your self, I strongly recommend that think again. :-) DLMS is very complicated protocol. I believe that you can read simple data objects quite fast, but complex data where data is split into multiple PDUs and ciphered is taking time.

Hi Rohit,
Please, create a new topic if you have the new question.
Are you using GXDLMSDirector or client example?

Hi,
Hi,
i'm using c#.
I don't need to read bytes by myself, but i need to access specific informations from the meter, and i need to figure out how to do that using gurux DLMS c# library.
according to my knowledge (which might be wrong) different informations are described by an OBIS identifier, a class ID and an attribute id.
i have the XML, how can i make a request to the meter?
Reading the meter.
Hi Swappage,
Download GXDLMSDirector and use that to study your meter. Each meter must implement association view. Association view tells what kind of functionality meter is offering (Left side of GXDLMSDirector under the meter).
After you can read your meter with GXDLMSDirector study Gurux.DLMS.Client.Example.Net or Gurux.DLMS.XmlClient to read data what you want from the meter.

Hi Mikko, thanks for your
Hi Mikko, thanks for your kind reply, i cant use the director because it's a GPRS device.
In fact i'm using the example from the github repository as a starting point for my code.
I can get the device to connect and i can read certain informations like (as said), LDN, but i cant figure out how to read properties that have a different class id

Hi Swappage,
You need to create the object and then read it like data object.
Something like this:
GXDLMSClock cl = new GXDLMSClock();
client.Read(cl, 2);

Hi, sorry for the so late
Hi, sorry for the so late reply.
I'm still grasping on it :)
I've noticed that there are a bunch of objects that are ready to use, like clock, as you suggested.
But is there a way to create a custom object?
