DAQread stops without errors

I control a measurement setup with a CompaqDAQ and read voltage values with a DAQ-9205. The DAQ-9205 is read with a finit sample number (30) and a rate of 1k configured in the task. What happens is, that the programm stops suddenly (maybe about an hour, but not allways the same time) in front of the DAQmx-read-VI (LabView2010 function). You can see running the error cluster in the read-VI but not coming out, the program just stands still without an error. Has anyone an idea what happends here?

 

PS: I fixed the problem by using an express-VI. There the program does not stop. But for higher performance I what to split the DAQ-Init and the DAQ-read.

Hi

 

Could you please upload your VI so that I get an impression what might be wrong?

 

You should always try to use all of the VI's shown in the example VI to get highest performance results.
