Is it possible to get the total number of channels/lines configured in a task?

[Nagraj B]

Hi,

            Is there any fuction to get the total number of channel count configured for a particular task for PCI 6229?

For eg Task1 uses 5 digital input line. Is there any function to get the total number of lines configured for the Task1 when I pass the taskHandle of Task1.

Regards

Hello Nagraj,

I think what you want to do is to use DAQmx Read property node Advanced -> Number of Channels. This property returns number of channels you have configured in your task.

I hope it will help 🙂

Hi Stefo,

         I am using CVI for my application. I got the solution for my question. 

int32 DAQmxGetTaskAttribute (TaskHandle taskHandle, int32 attribute, void *value, ...);

Using the above function we can obtain the task attributes.
