Hello: This error occurs when you are trying to output data from the DAQ Device faster than your program is telling it what to write. This usually occurs if your while loop is taking too long to execute. Possible solutions would be to increase the number of points that you write at at time or decrease the rest of your code in you while loop. Start with the LabVIEW shipping example "Continuous Generation" located under Help >> Find Examples... See how fast that example will run because it is optimized for speed.
Good Luck! Sincerely, Brooks B Applications Engineer
