SubVI filter not executable. Undefined error.

[David_Pastorino]

Good morning,

During the development of a bigger labview project, I came to need filtering of my waveforms at some point. I am getting a broken arrow signaling the filter assistant :

"SubVI 'Filter' : SuvVI is not executable"

I thought it could have something to see with the whole program and thus created a simple VI of acquisition from a myDAQ aparatus and had the same error.

Do you have any idea how I could at least identify the error?

Thanks in advance,

David

If you open the SubVI Filter and hit Ctrl+R LabVIEW should tell you what you need to fix in that VI.

Thank you,

I get the error : "This VI claims to be part of a library that does not include the VI. The VI might have been deleted from the library. Add the VI to the library again or select File - Disconnect from the library."

Still, the "Disconnect from library" option does not work (no effect) and may actually not be the solution.

I am a bit confused about the problem as I am running a fresh installation of Labview from the beginning of the project (Labview 2011 32bits)

I realize right now that the exact same error message appears when using the Tone Measurements assistant VI.

However I can use for instance the Spectral Measurements assistant VI without error.

Any clue?

Anyone have a solution for this or more debugging ideas? I am having exactly the same problem. The Filter and Tone Measurements Express SubVI's will not execute, but the Spectral Measurements Express SubVI works fine. I created a simple VI with these components using their default properties. I've attached a screenshot of the block diagram, front panel, and error list. I'm using LabVIEW 2011 SP1 (32-bit).

David,

That is what I did to go on with my project:

1. Re-install everything : Did not change anything

2. Create a blank vi, put a VI filter in the block diagram (this should not be functional as it is not wired), copy it and paste it in my other project. I believe if the filter is the first vi of a blank project, it is funcitonal and then you may copy it wherever you need to.

That is no solution but I hope it helps.

You need to open both your Express VIs (Tone measurment and Filter) and edit the settings, I think that if these two are broken it's because the settings are either not properly done or not compatible with your hardware.

At this point a re-install is not a good idea I think.

[David Englund]

David, you saved my life. Your second suggestion worked!  I've been at this for hours, trying to get a non-express butterworth filter working. Thanks a ton. Cheers.

[David_Pastorino]

I´m happy for you David. It´s actually not a solution and it suggests we are doing something wrong somewhere about sampling/generating/acquiring. Still, it alows to go on.

Bye

#2 Also worked for me. Frustrating, but it worked! In my case the data is read from a spreadsheet CSV file. No hardware involved. LV 2011 SP1, 32 Bit on Windows XP.
