Hi,

It is possible to change them in LabVIEW  

Dynamically Change the Lines in a DAQmx Analog Input Task Using an Event Structure   https://decibel.ni.com/content/docs/DOC-7103

Thereferore it should be possible in C too.

Hello,

thanks for reply.

If I understand correctly you need to clear-dispose task and then create new task. This takes quite some time.

Isn't it possible to create task than START, acquire signal, STOP, UNRESERVE and then reconfigure channels in task(remove old, add new)?

Regards!

Hi,

Unfortunately not.

In order to change physical channels DAQmxCreateTask(), DAQmxStopTask() and DAQmxClearTask() has to be used.
