NIDAQmx 17.6+,can't distinguish which channel the data comes from

[ShuraDK]

Hello guys:

    I am trying to create a task to read several analog input at the same time.  With the following code,the data I received will be saved in parameter Sdata;But the data comes from multiple channels and I can't  Distinguish which channel the data comes from.Is there any method likes "key--value"

or any other functions?

Thanks

And finally,please regard me as my English is so poor;

*****************************

int32 read=0;
float64 Sdata[6000];

DAQmxReadAnalogF64(taskHandle,1000,10.0,DAQmx_Val_GroupByScanNumber,Sdata,6000,&read,NULL)

*****************************

Best

Hi,

I think this example will be useful:

It saves data from each channel to a different column.
