I'm tryng to read LDN drom a meter .
The APDU Text generate from Gurux C# is:
7e a0 19 03 21 54 5f de e6 e6 00 c0 01 81 00 00 00 00 2a 00 00 ff 02 00 ea 00 7e
No response.

But the ic class must be set at "01":
The correct sequence is:
7e a0 19 03 21 54 5f de e6 e6 00 c0 01 81 00 01 00 00 2a 00 00 ff 02 00 17 4d 7e
and the response is:
7e a0 22 21 03 74 ba d5 e6 e7 00 c4 01 81 00 09 10 53 4d 47 52 30 33 36 31 31 36 30 32 39 33 34 36 cf 31 7e
The source is:

GXDLMSObject oggetto = new GXDLMSObject();
oggetto.LogicalName = "0.0.42.0.0.255";

DataType tipo = DataType.OctetString;
oggetto.SetDataType(2, tipo);

Object x = comm.Read(oggetto, 2);
where
comm = new GXCommunicatation(dlms, media, iec, auth, pw);

Can you help me?

Hi,

I do not know this meter. You should try to read Association view first. It will return all the objects what meter can offer.

You can read your object changing
GXDLMSDataObject oggetto = new GXDLMSDataObject("0.0.42.1.0.255")

BR,
