Hey jith,

You'll need to group your various channel configurations into the same task, but you can accomplish what you've described.  You'll run into some difficulty with the number of inputs you've described since the 6221 only has 16 analog inputs.  You can actually re-use inputs for different configurations, but you'll need to be careful that you don't cause improper readings.  Ideally, you would have a card with enough inputs for the various transducers you mentioned.

There are a numerous resources available from NI.com and within LabVIEW that are great tools for getting started with your acquisition application.  I can point you to some of these and encourage you to ask any questions you may have while developing your VI.  I also uploaded a screenshot that shows how multiple configure channel VIs can be used in the same task.  Note the different names - this is a must.
