applying delay in formula node in labview

[to0raj]

hi every bod

[Yamaeda]

Why would you want one? (i dont think that's possible, you'll have to split the formula and set a delay in between)

And i who thought my post was the solution ... (you can untag posts if needed)

I think tagging is correct: the solution is that there is no solution!!

Hello to0raj:

I'd really like to help you with this issue!  Could you please describe exactly what you want to accomplish and possibly the application of this project?  Can you please tell me what version of LabVIEW you are using and what operating system you are running?  Has anyone of the previous comments solved your issue?  Thank you very much!

hi greg actua

Hi Greg  

actually I described it twice

but I don't know why in has not been published in the forum

I wanted to make a Boolean object one second on and then one second off

firstly I decided to use the formula node

its pretty easier than other applications in labview

but when I tried to use the delay as I learned in micro controllers: "delay_ms(1000); "

it didn't work

and then I posted this question

but the description of my request has not been publishes and only the title came on

finally I used two for loops one inside another one

I just started to learn labview and I don't know all items here

but thanks for reply

If you have not done so yet, please go through the free on-line tutorials about LabVIEW.

Rarely is the formula node the most appropriate way to write code in LV.  The native LV constructs may be a bit awkward at first for someone with a text-based programming background.  Once you learn to use dataflow and to recognize the functions by their icons, you may find that graphical programming can be both powerful and easy to read.  

For delays use the Wait(ms) function found in the Timing palette.  If you need a delay in the middle of a calculation (which seems unlikely), you may need to split the calculation into two parts and put the Wait (ms) between the parts.  See the image below for one way to do this without any formula nodes.
