VI's for counters and timers.

[dheeraj2102]

Can you please tell me how to use counters and timers in LabVIEW NI-DAQmx? I am new to this software and I want to know what VI performs the counter/timer task. In traditional DAQ VI's, I have seen a couple of counter and advanced counter VI's but they don't work. Please suggest me the appropriate VI's in NI-DAQmx.

Also, can you please advise me how to use timers and counters to calculate frequency of a square pulse? 

Thanks

Be sure you have DAQmx drivers installed. Then you can find many prepared examples in Help -> Find Examples, where you can browse to Hardware Input and Output -> DAQmx -> Counter Measurements. Here you can find many examples - you just need to specify the board you use, and connect signals properly to terminal block.

If you are looking for how the frequency measuremen is made, then I recommend you to see M Series User Manual (or E or X Series), Chapter 7 - Counters, section Counter Input Applications, part Frequency Measurement.

if anything doesn't work, it would be useful to specify what board do you use, what drivers you have installed and what you try to implement.
