DAQmx tasks

[RedRider]

Is it possible to run multiple DAQmx tasks on a single device at the same time? On a PXI-4204, I need to do a 1 point sample on ai0 every 100ms or so. The timing is not critical on this, so right now I am simply doing a 1 channel 1 point DAQmx AI task every 100ms in a loop. While this loop is running continuously, i need to randomly sample 1000 points at 1000 Hz on ai1 on the same card. When I try to start a second task after either of the two are first running, I get an error.

Is there a way of doign this? These two tasks need to be independent of eachother, but sometimes must run at the same time. This is a simplified version of what my application requires, but if there is a way to do this I can figure out the rest.

I am not too familiar with DAQmx and the 4204 yet, perhaps I am going about this the wrong way. Any input will be much appreciated.

Hello RedRider. Thank you for contacting National Instruments. You cannot do more than one analog input task at a time. There aren't enough resources on the board to do this, you will have to do them one at a time. You can incorporate more than one analog input into a task, but this won't work with your situation. If you would like to make a product suggestion to do this in the future, click Product Suggestion. Hope this helps. Have a great day!
