Usage of Event Structure and push button

[dogukan12324]

Currently, I’m unable to share the VI file, but based on the comments and my own research, I’ve tried three different approaches. However, since I couldn’t resolve the issue, I wanted to ask for your help.

So you show 3 different images with just small parts of your block diagram!?

None of those images allow us to help you…

You should step back and start over with the Training resources offered at the top of the LabVIEW board.

Especially focus on "THINK DATAFLOW!" as the basic LabVIEW mantra: you cannot connect two data sources with a wire!

• Why do you think you need to use a case structure to output a TRUE values from a case that is selected by a TRUE value???
• Why do you think you need to use a local variable of the "stop" button?
• Why do you still think you need to connect two data sources even though we recommended to use a boolean operation? You want to stop your VI on "time elapsed OR stop button"…

I'm trying to understand what you've explained — this is my first LabVIEW application.

I tried to use the Case Structure like an if-else block. I thought that if the elapsed time reached 60 seconds, the structure would enter the True case and return a True value, which I could wire to the While Loop's stop terminal to end the program.

As a simple attempt, I also tried using a local variable of the Stop button in my application. My idea was to send a value to the Stop button when the time reached 60 seconds, so the system would stop. It was a basic test approach.

Best regards

I have now completed the assignment... I finally realized my mistake — I had been struggling with this for days just because I didn't use the OR block... After adding the OR block and making a few small adjustments, I was able to complete it. I might have been a bit frustrating and annoying while working on this assignment... But completing this assignment taught me a lot. I sincerely thank all of you.

So you need a case structure that outputs a TRUE when the selector condition is TRUE? why not use the selctor condition itself???

This is called "Rube-Goldberg code" and there is a whole thread with bad examples…

You still don't understand you should use a boolean function (like OR) to handle two stop conditions?

Have you learned anything about boolean logic (independently from LabVIEW)?

Edit: we wrote our messages nearly the same time. It's nice to know you solved your homework!

If you have a true case, you already have a true value wired to the condition terminal. Use that directly. No case structure needed.

Hi,

I want to place the system I designed into a box to make it look better. However, it stays behind the box, like in the example. How can I fix this?

Best regards.

Use the Z order options in the frontpanel menu bar…

I don't think it will look "better" when you place rectangular decorations on the frontpanel.

Do you know any other software with a similar GUI design?
