I'm just throwing this out there to see if anyone else has had this problem. I have a M series DAQ card connected to an SCXI chassis that has a thermocouple module in it. The issue I'm seeing is that after a power failure, when the labview application starts talking to the card again it gives back an empty array of data from the DAQmx vi's (with no errors). The solution is to re-create the DAQmx channel configuration. If the system is shut-down and re-started gracefully then all is fine.
