Is it possible to change the thermocouple type (at run time) for a 9211 daq module ?

thanks for hints,

Yes, you can.  What hardware platform are you using?  cRIO, cDAQ??

hi

i am using a compact daq (96... something, I am at home now). I don't know how to do it (I prepared the task iwith MAX). thanks for helping me out, I am new with DAQ (I used a lot of Keithley and Agilent DMM before but not NI hardware).

hi again,

it's a 9211A connected through a USB-9162.

thanks again,

What you want to do is use the daqmx functions to create your virtual channel inside your labview program instead of from MAX.  This is very easy to do and then you can change any of the setting of the virtual channel that you like.

This is a simple example of how to create the virtual channel.  This is a simple software timed acqusition using that virtual channel.  Notice how you have all the options of the TC channel in the create virtual channel function.

Hi,

I you want then to change the settings of your task during the run time, you will have to stop the task/change the settings/start the task.

You can also use the DAQmx Control task vi which is done for that purpose : How Can I Control Which DAQmx Task is Running?

Or you can think of the following example and changing it a little bit to comply with your needs.
