Hi,

Thanks a lot for your kind help.

The connection has been established between the DLMSDirector and ER300P meter with Indian standard. And I am able to read registers from the device. I am also able to see the OBIS codes and attribute indexes of the objects in the DLMSDirector application.

I want to write code with the help of "GuruxDLMSClientExample" to communicate with ER300P meter. So I have written the below mentioned code. In the below mentioned code the connection to the ER300P meter has established and I am also able to read clock object from the ER300P meter. But I am not able to read other register object. The "GetErrorMessage" returns error message "Access Error: Device reports a unavailable object" while same object is accessible from DLMSDirector app. Refer below mentioned code.

Kindly suggest me. What should I do?

//---------------------------------------------------------------------------
CGXDLMSClient cl(true, 16, 1, DLMS_AUTHENTICATION_NONE, "xxx", DLMS_INTERFACE_TYPE_WRAPPER); CGXCommunication comm(&cl, 5000, trace);

if ((ret = comm.Connect("192.168.000.003", 4059)) != 0)
{
TRACE("Connect failed %s.\r\n", CGXDLMSConverter::GetErrorMessage(ret));
return 1;
}
if ((ret = comm.InitializeConnection()) != 0)
{
TRACE("InitializeConnection failed %s.\r\n", CGXDLMSConverter::GetErrorMessage(ret));
return 1;
}

std::string value;
CGXDLMSRegister *obj = new CGXDLMSRegister("1.0.1.8.0.255");
if ((ret = comm.Read(obj, 2, value)) != 0)
{
TRACE("err! failed to read register: %s", CGXDLMSConverter::GetErrorMessage(ret));
}

comm.Close();
