labview run example

[Melikyan]

Dear Mr./Mrs. I make the program by Labview and need to put the run button the same as the top run (ctrl+r).

Is it possible to put Bulean Run parallel with the program Run? Please help me...

If have an example please atach...I use Labview 8.0.

Sincerely

No, you can't create a button on your front panel that starts the VI running. The best you can do is set the VI properties such that it starts running as soon as the VI loads into memory.

What is it exactly that you are trying to accomplish? How do you want the user interface to work?

Mike...

Mike is correct. In order for the code to read the boolean, the VI needs to be running already. Catch 22 😉

You can always set the VI to "run when opened" and have the code start in a wait state. Pressing the button would switch the code to a more productive state. 😉

(In 8.2, there is actually a way to start a VI from a front panel button but discussing this would exceeed the scope of this thread. Its not practical anyway. ;))

Dear Mike thank you for your response. I atach the vi...If impossible last way, next way is to run the program the top, then put Bulean to run the measurement....

After 1 measurement I want second measurement on same Graph Indicator and stop the program...

I mean Push Bulean go 1st progress, finish show the graph, then wait a litlle, then go next progress and show the 2nd graph and stop...

If I want push again....2 progress again...

Thanks a lot....

Just place it inside an event structure that fires when the run button is pressed.

(Of course the entire thing should go inside a while loop so you can run multiple times. Modify as needed)

[Melikyan]

Thank you very much....I want only 2 times to run...and stop, and push again and work again...

But I don't want that the top run(ctrl+r) stop. I want that stop only Bulean Run after 2 cycle...And push again, process again..

I used For loop N=2, but when I put Time Delay....First process go, then wait, then go second cicle, then wait and stop...

I don't want the last Time delay...I want only after 1cycle measure, wait, then go next cycle measure.

Once more time thanks a lot...

[Melikyan]

Dear Altenbach, I attach the vi that I want....But where put there "Time Wait" control to delay the time only after first measurement...

[Melikyan]

Dear Altenbach I have a question. If program run, after 1st cycle I cannot input the time delay, and then continue 2nd cycle, please recomend what way have to input time delay...

I need only 1 time delay between the first cycle and second cycle.

May be change "For Loop"...But how?

[pincpanter]

Put the wait node into a Case structure and run it only when the loop index is =0

[Melikyan]

Hello dear Paolo. Did you open my last Vi...? How can I do?

If you have a free time, please change the Vi and attach...I don't understand what you mean...
