Gurux.DLMS

Hi,

I'm working on TI - MSP 432. i am toltaly new to DLMS protocol, i took
Arduino client code from gurux library and i ported serial communication to
MSP 432. Now i can able to read the DLMS_OBJECT_TYPE_REGISTER values.

bb_init(&frameData);
//Set frame size.
bb_capacity(&frameData, 128);
cl_init(&meterSettings,1,32,1,DLMS_AUTHENTICATION_LOW,"lnt1",
DLMS_INTERFACE_TYPE_HDLC);
cosem_init(&reg_value.base, DLMS_OBJECT_TYPE_REGISTER, "1.0.14.7.0.255");

gxRegister reg_value;
if(com_read(&reg_value.base, 2) == DLMS_ERROR_CODE_OK)
{
Reg_value = reg_value.value.lVal;
}

But i dont know how to read DLMS_OBJECT_TYPE_DATA and
DLMS_OBJECT_TYPE_PROFILE_GENERIC,

please help me in this, How to read both data.

Thanks & regards

Hi,

Check GuruxDLMSClientExample. That reads the association view from the meter and reads all the data.

You can read all objects in the same way as register.

gxData data;
int ret;
const unsigned char ln[6] = { 1,1,21,25,0,255 };
if ((ret = INIT_OBJECT(data, DLMS_OBJECT_TYPE_DATA, ln)) == 0)
{
if(com_read(BASE(data), 2) == DLMS_ERROR_CODE_OK)
{
}
}

Hi Ajmal,

There are several ways to read profile generic. Check GuruxDLMSClientExample. It'll read historical data by range and entry.

Hi,

Can you try to read your meter with GXDLMSDirector? Make sure that you can read same profile generic that you try to read. Let me know what happened.

Hi Mikko,

Yes I can able to receive data from GXDLMSDirector. i just called the function "com_readProfileGenerics" i don't know what changes to be done in the function.

when i call the function it is not entering into the For loop, please find the attached screenshot

Thanks & Regards

Hi Ajmal,

Did you read capture columns first (attribute index 3)?
What OBIS code you try to read?

Hi Mikko,

Thanks for your replay. Yes, i am calling the function still i am facing the same problem. please check this is the correct way to call the function

gxProfileGeneric profile_g;

cosem_init(&profile_g.base, DLMS_OBJECT_TYPE_PROFILE_GENERIC,"0.0.99.98.0.255");
com_readProfileGenericColumns();
com_readProfileGenerics();

After calling this function in which structure i will get the data.

Thanks & Regards

Hi Mikko,

Need any permission to read Profile Generic

gxProfileGeneric profile_g;

cosem_init(&profile_g.base, DLMS_OBJECT_TYPE_PROFILE_GENERIC,"0.0.99.98.0.255");
com_readProfileGenericColumns();
com_readProfileGenerics();

Thanks & Regards
