How can I find a list of internal channel of a chassis or any other device using NI-DAQmx?

Hi, 

I want to use the internal counter channels on my cDAQ-9178. I know I can use _ctro for my physical channel name when creating counter channel. Is there a way I can enumerate all the available internal channels on a device. I am using the function

DAQmxGetDevCIPhysicalChans

for listing all the channels on the device. But when used on the chassis, I do not get a list of internal channels. I found KB on how to do it with LABVIEW but can not find a way to do it programmatically using NI DAQmx C API.

Best Regards,

Manisha

Hello Manisha, 

For the internal channels, you need to hard code them. You can find a list of internal channel names at the following link: http://zone.ni.com/reference/en-XX/help/370466V-01/mxdevconsid/internalchannels/
