explanation

hallo

this may sound a littel bit ridiculous , but  I need some explanation ...... I creat a SubVI and later I add a function with Boolesch als results. The problem is that  I couldn't see the boolesh in the SubVI icon . Why ? and what should I do ?

Thanks

Hi dctoni,

can you upload your code? What do you mean with "i couldn´t see the boolean in the subvi icon"??

Hi Mike

I attached 2 Pics . 1 from the SubVI icon and the other one is from the blockdiagramm of the subVI.

what I want to do, is the following , i would like to add this function ( if( End1==Position1 & End2 == Position2) ----> Stop the while-Loop)  outside the SubVI, but I couldn't do it . so i decide to put it inside the SubVI with a boolean . so I can use the boolean to stop the While -Loop

Hi dctoni,

i think i understand what you want to do, but where is the problem??

Hi Toni,

you "can't see the boolean in the subvi icon"? Have you connected the boolean indicator with the connector pane???

Btw.:
Did you ever think 25 in/outputs are too much for a single subvi?
Why not create clusters of things belonging to each other? There are several in/outs named ***1 and ***2... Why not group all ***1 in a (typedef) cluster and all ***2 also? Or make an array of clusters, when the clusters are the same structure?

Hi Mike

the problem is that I am using a while-loop and I want to stop it after that funktion , the first thing what i 've done is that I've added that funktion  outside the SubVI , it doesn't work there was a error ( see Pic1 ) so I decided to add it inside the SubVI using the boolean as a signal( see Pic 2) , so when the boolean turns on the while loop Stopes , and in Pic 3 you will see that the boolean didn't appear.

that is my question why ? and if there is a way how should I do it ?

Thanks once again for your help

Hi Toni,

in pic1 you connected an input of the subvi to the "is equal" function - when you move the mouse on the red "x" of the wire you would see the error in the context help!
You cannot connect two data sinks without a data source!
Pic2 looks ok - but it's only a very small portion of your vi don't showing the sources of the boolean wires.

Could you please attach both main and subvi? There seem to be more problems than this...

Hi dctoni,

did you read GerdWs post? In your pic1 the problem is that you don´t connect a control. You can´t connect only an input of a subvi to a comparator.
