Is it possible to run 2 Labview programmings at the same time with one DAQ card, different ai channels. Now, I am using USB-6221 and Labview 8.2. If it is possible, please recommend me. I have tried, but I got errors. Thank you.
No, it is not possible to have two separate programs running a DAQmx task on the same board. You can't have two separate analog input tasks in the same program either. You only have a single A/D convert clock. You could have a single program with a single task that reads both channels or if you want separate analysis programs, you could have another program that just does the acquisition of both channels and publishes the results to something like datasocket or a shared variable.
