Hi,

Is it possible to read all instantaneous profile value using single OBIS code?
I mean can I read all (current, voltage, power, etc...) using single OBIS code.

Kindly suggest me.

Thanks & Regards,

Hi,

This is not possible. You can read several objects in one request. All meters don't support it.
Use ReadList-method for that.

Hi Mikko,

Kindly refer the below mentioned code. After My sample application is not true for first condition and true for second condition. Is it means my meter does not support "readList" method?

Kindly find the attached file of my program and its output. The method "readList" has failed and showing "Invalid Parameters" error.

Kindly suggest me asap.

//First Condition
if ((cl.GetNegotiatedConformance() & DLMS_CONFORMANCE_MULTIPLE_REFERENCES) != 0)
{
// It means readlist is supported ?
}

//Second Condition
if ((cl.GetNegotiatedConformance() & DLMS_CONFORMANCE_MULTIPLE_REFERENCES) == 0)
{
// It means readlist is not supported ?
}

Thanks,
Pradson

Hi,

You are right on this. If DLMS_CONFORMANCE_MULTIPLE_REFERENCES bit is not set meter don't support readlist and all the values must read one by one.
