Copies of Sub VI's created in a case structure returns a zero array.

[avinash_g]

The original sub VI returns a finite value in the case structure.. However when a copy of the subVI is created for different values of input in the same case structure, the output array is indeterminate. Please send in your solutions to abhardwa@engin.umass.edu.

Maybe you can attach a example program that demonstrates the problem. We cannot thell from your decription what is significant or even what the problem is.

• Why do we need to crete a copy of the VI (I assume under a different name)?
• What if you feed "different values" to the original VI, do you get the same undesired output?
• What is "indeterminate"? (empty array, array of zeroes, array of NaNs, etc.)
• What is in the different cases of the case structure?
• Are some output tunnels set to "use default if unwired"?
• What is your LabVIEW version?

In general, answers should be posted here in the forum so everybody can profit from the solution. Providing solutions via private e-mail should be strongly discouraged. 😉

hi..

*  the LabView version i'm using is 7.1

*  the indeterminate array is an null array (array of zeroes)

*  when a different input is wired to the original SubVI, the expected waveform is predicted.

*  the case structure represents different inputs which are wired to the same SubVI in the 2 instances.

hope this should be of help.

Sorry, It is not clear what you are saying:

• Do you simply have a second instance of the same subVI or do you create a copy with a different name?
• What is the size of the "array of zeroes", ... or is it an array of zero lenght?

You should attach an example of your code to make things clear?
