Iam using NI PCI-6071E DAQ board for data acquisition.Iam able to read analog inputss,by using datalogger iam able to see the measurement as -5 volts.But the problem is iam not able to read Digital i/os.I would like to know how it will display in datalogger,I mean, wether it will show 1 and 0 or some thing els.I tested with example VIs,in this examples the LEDs are glowing green after i run the VI,but after deleting the channels from the MAX still the VI is showing green LEDS when i run the VI.
