Using LabVIEW Case Structures

You can use LabVIEW Case Structures to programmatically execute sections of graphical code based on certain conditions. This is similar to "if... then... else..." statements in other programming languages.

Awesome short//to the point videos. Love all the little subtle things you do (i.e. move a box around with the arrow keys) which hint that this functionality exists!

Right Click >> structures >> Case structure drag and select the area of Blockdiagram where you want the case structure to apply >> Add a contoller in the front panel and control the corrosponding cases using the switch

Amazing explanation ...Dude we need more videos from you ....

How can I switch different images in the same position by using Case structure?

Instruction is very clear and understandable. Wonderful Job!!!

I keep encountering situations in my code where I'd like to do something "IF" a certain condition is met. However, if that condition is not met, I don't want to do anything. My problem arises when I (in the positive IF case) am in some type of loop and I want to act upon an item that is part of a shift register or is in a tunnel. If I'm in the FALSE case, I don't want to add to my array, or increment a counter, etc. How do I implement a "Do nothing" yet satisfy my tunnels?

My daq asst in express input menu is missing, can you advise me what to do?
I have 2017 labview. Thanks

We recommend asking an engineer in our forums about this: (forums dot ni dot com). Be sure to link the video when asking your question, and they'll be able to help you out. Good luck!

@Labview Thanks I actually completed the hysteresis level by using case structures and it works brilliantly!!! Labview is an amazing intuitive development program and wonderful to use!!

[olajideoyekunle]

thank you for the video. it's explicit. but please am new to labview and considering giving it a chance. my question is so how does implement all the graphical coding into a project, say I want to transform all that into a real independent board to use in a circuit?

[Liartar]

I need to admit, having extensive experience in text-based programming languages, that before I saw these videos I thought that LabView is very confusing and counter intuitive. Now I know that it is not and even see how this way of programming has some appeal to it.

[jamesmclean]

This saved me so much time. Thank you.

@lisalee150 The easy answer is yes this can be done. If you are looking for how to implement this then I will direct you to "ni dot com slash forums" (YouTube doesn't allow links in comment for some reason) where you can get more specific help on your application.

I've had a little difficulty in using this. I'd like to implement an if-then case structure, but I'm not able to get the hang of it in Labview. My condition is -- if x> constant 1, then, output = constant 2.
But I only get a true or false as the output of my comparator, not a constant.
Can anyone help with this? Thanks a lot !

[Zofim]

Oww yeah!
I can understand a little more about LabVIEW now!
thanks very much!

[lisalee]

I find that this is very helpful and clear in what you teach. I would like to know though how using arrays I would be able to use hysteresis in a low level/high level situation. I have a tank of water and at 0V it will activate a pump to fill the empty tank....when the high level of 10V is reached it will switch the pump off but must only activate the pump again on reaching 2V so that the pump is not switching on and off at the high level. Is it possible that Labview version 8 can do this?

wher is the labview coching in hydharabad

[paul]

what about combo box and case structures... D:

[includemeatmjackson]

Dude that was Thanks. Really helped me a lot!!!
