call a sub vi with a while loop in it

[raghavendra]

hi..

i have a code vi in which, there are cuple of ring controls and indicators...
which are inter dependent based on selector values,and i used shift registers in while
loop to see if the index of the ring controls are changed....

now i woould like to this vi as a sub vi....where i am not able to get, control once the vi is called...if i replace a for loop instead
of while loop ,the program behaves randomly......

can anybody suggest me how do i call a sub vi aith a while loop in it.

Hello,


If your SubVI inputs are references then any modification of their value into the MainVI is reflected into your subVI.
From what you said about randomly behaviour it looks like you have an initialisation problem. Shift register must be initialised otherwise it behaves like a memmory.
If this eplenations aren't usefull attached a simplified example and we can modify it, and maybe could offer you more solutions.

hi

i have attcahed the the zip .vi.

there are 2 ring controls....where in the values can be selected source res/source res2.

the other 2 ring controls are indicators c current/c range.
based on the selection there are 2 numeric indicators hidden and the
range limit are set to the numeric controls clamp hi and clamp lo and a stop button
to contol the loop.

since changes are based on the ring controls, i am using shift registers
to monitor the changes.

if i want make this parth.vi as a sub vi and call it....due to while loop
i am facinga problem...other than creating a global variable for
stop button...can you thnk of any avenues.
