Hi Kurumi,

I would like to read multiple object/OBIS Code using ANSCI C after connecting to DLMS meter at the same time would like to print value in readable format.

My idea is

1. Collect all the OBIS code - How to create multiple object list
2.read one by one and print its value based on data type in readable format

Please provide some psudeo code stuff

I am bit confused with readScaler and readList

I want to make it simple like
1.Create an array of obis code list
2.use com_read()

Thanks
Vijay

Hi Vijay,

You can read multiple object like this:

objectArray objects;
oa_init(&objects);
//Add objects that you want to read:
arr_push(&list, key_init(obj, 2));
ret = com_readList(connection, &list);
arr_clear(&list);

Hi Mikko,

Thank you for reply. please correct me if am wrong in the code.
objectArray objects;
gxArray list;
gxClock clock1;
gxData cumBC;
con_init()
cl_init()
com_initializeConnection(&con);
cosem_init(&cumBC.Base,DLMS_OBJECT_TYPE_DATA,"0.0.0.1.0.255")
cosem_init(&clock1,DLMS_OBJECT_TYPE_CLOCK,"0.0.1.0.0.255")
gxObject *obj = BASE(cumBC);
gxObject *obj1= BASE(clock1);
oa_init(&objects);
arr_init(&list);
arr_push(&list,key_init(obj,2));
arr_push(&list,key_init(obj1,2));
com_readList(&con,&list);

But am not getting expected result. Below is my trace

Hi Vijay,

Can you make a connection to the meter with GXDLMSDirector. There are Proposed and Negotiated parameters.

Can you see MultipleReferences in Negotiated? If not, your meter is not supporting this functionality
and you need to read values one by one.
