Hey guys,
I would like to first thank everyone that has helped me with this. I have been on here for about 5 days with questions and everyone has helped me. I am new to this, I had never programmed in labview before. So thanks again.. My question I have now is changing the data acquisition names like the first one in the freq & measure is AI voltage I want that to be CI frequency. I thought it would be a simply switch but I am not able to figure out how to change it. Same thing as the next one I want to make it implicit. Then my final question is I need data aquistion to take the in data from the read data acquisiton block. So it would take in the data, along with the users pulse per rev. an output the speed along with an error out. I hope this makes sense if not I can explain better.

This is a way you can measure your frequency.
But you really have to explain the speedObtained.vi because I really don't get what you are trying to do.

You mean you want to regulate the system. So you can control the speed depending on the input signal.
Have a look at this: http://en.wikipedia.org/wiki/PID_controller.
