delaying an enumeration

[rscott9399]

Hi

I have a VI that is very complex that i did not write. Needless to say life is difficult right now

I need to do the following. 

The VI outputs a certain enumeration if there is no error.

AKA a complete bit 

However, the complete is happening to fast. I would like to delay the output of this enumeration just by a second

Is there any simple way to do this?

Thanks

It would really be nice to see some code or even like just the concept to see what you're talking about. Have you seen this VI?

This might be perfect. 

I dont see it in my labview

Where can i get this?

Thank you so much

I have gone to the example folders and found the folder but its not in there

I have 3 basic examples but not a VI with that in it

I am running 2017 pro

Is there anyway you could post it for me.

You'll find the function on your palette under Timing.

Alternatively press Ctrl+Space and write "Stall Data Flow", it should appear in the list.

Basics lesson 1 has that VI in the lower right quadrant. You can also search for the VI by name using quick drop

Also, on the help page it tells you the owning palette (Timing VIs and Functions) so you can find that VI.

[rscott9399]

yes im familiar with the quick drop

It was not there for some reason, i dont get it

[rscott9399]

I dont how this is possible 

[rscott9399]

I have discoverd what the problem is

This is a CRIO real time application

The Stall Data can not be used on the RT side apparently. 

When i go to my host i can search for the VI and it will come up.

So back to the 20 million dollar question, how do i delay this data flow for a split second on the RT side

 

[infinitenothing]

It should still work in RT even if it doesn't show up on the pallets. Try it. Or, check out the underlying code and copy that.

[rscott9399]

I did try to copy the VIM from the example and import it into the RT part of the project

It gave me a conflict that appears to be caused by the fact that LABVIEW knows the file is there but i am telling it to use a different path which is just a copy of it saved to my desktop

 

[rscott9399]

I took care of the error and got it to deploy

Lets see if it works, stand by

Thanks for your help! 

Will post results in a minute

For reference, here is a comparison of how it was done before Stall Data Flow existed (prior to 2017).

The stall appears to have worked. You all are Steeley Eyed Missile Men

10 points if you can name that movie

It's like real life - overpromised and underdelivered. Now others have to fix it 😋
