I have a USB 6259 running with LabVIEW 7.1. I realize this does not have a built in watchdog function, but I have a piece of hardware that I plan to attach to the digital output of my USB DAQ device that will be my watchdog timer. I am uncertain, however, of how I can program this. I need it to be on for 5 seconds, then off for 5 seconds, continuously. Will doing this slow the rest of my program down to only loop every 5 seconds? If so, I can't have that. I don't know where to begin to program this loop. I have just become confident in my ability to program using analog in/out, and now the digital is throwing me off. My process will be acquiring data, and controlling a couple pumps, which is why i need the watchdog...to shut them off in case of a computer failure. Help is appreciated! Thank you.
