Want to learn more about shift registers and formula nodes

[kevin]

I am new to Labview and have looked at the example files and help files regarding shift registers and formula nodes. I was hoping that someone has a simple and detailed VI expaining how each of them(shift registers and formula nodes) works.

Have you searched in the VI library in your Labview install? See attached picture to see where it is. You could also search this website for tutorials. If you are a beginner I would recommend the book "Labview for everyone." It will get you started quickly. The Labview user manual will also explain exactly what the shift register and formula node do.
Sorry, no sample included

Yeah, I checked the VI examples. They were more complicated than I was looking for. I will check the book out.

Formula nodes are not one of the first things you will need to be looking at. look at the help files (press ctrl-H) for some syntax examples. Shift registers are easy: they carry the value from the end of the loop back into the start of the loop. The great power of shift registers is to use them without initializing. In that case they will retain their last value as long as the vi is in memory. This is a little more advanced topic, though.

I included a simple example that illustrates what a shift register does. Requires Labview 7.1

Good luck,

I figured out the shift registers and formula nodes a little bit. Thanks for your help. I won't be able to look at the last example you posted until tomorrow because I only have access to 7.0 today. Thanks.

okay, here's a picture of the block diagram. It is really very simple, but your question is kind of general.

Yeah, that's it. Thanks. Everything is good now. Thanks.
