Missing linear fit VI, lvanlys.dll FP-2000 won't run on desktop.

[upchuckjunk]

Seem to have isses with this VI that utilizes Polynomial Linear Fit VI. 

This is the error I get when I try to run the code from my computer, connected to the FP-2000 unit over the network.

Download completed with errors.

Any clues or helpful hints as to why this is happening? 

Thanks.

Hi,

Are you able to run your program on your host system?

[upchuckjunk]

Yes, it seems to run fine on the host.  I have looked for the lvanlys.dll files on the FP-2000 and they seem to be installed on the unit as well.  I'm at a loss as to why this doesn't work. 

Thanks,

Bill

Here is the error that I get when I try to run the polyfit VI on my FP-2000:

Deploying NI_AALPro.lvlib:General Polynomial Fit.vi
Failed to download NI_AALPro.lvlib:General Polynomial Fit.vi
LabVIEW:  The VI is not in memory.
LabVIEW:  Failed to load shared library lvanlys.dll:PolyFit81_head:C on RT target device.

I have found this .dll file already loaded on my controller, the VI runs fine from the computer.

Hi Bill,

The problem might software corruption on the target. Can you please format the controller and reinstall the software on it?

Hi Karunya,

I attempted to run the VI, PolyFit on another FP-2000, it seems to do the same or similar things.  Is the project interface trying to download the whole library?  If so, is there a way to load up just the fit vis for the application? 

Thanks,

Bill

Bill,

Since you are a math analysis function, you would need the whole dll to be able to run it and not just the upper VIs. Have you already tried to format the controller and reinstall all the software? If that doesn't fix it, I would suggest that you try to build an exectuable for the fieldpoint and still see if you have the same problem.

Hi Karunya,

Yes, I tried to build a simple Polyfit and the whole projects .rtexe file and it failed to start. 
I don't think this is a software issue, but I will try to reformat one of my units.  Another thought is to
split the library to gain access to the polynomial fit vi as a seperate VI.

I'll post back when I get some resoloution or more information. 

Thanks,

Bill

Ok, I reformated one of my FP-2000 units but it didn't change any of the failure issues related to the polynomial curve fitting.  Here is the error when I try to run the code from my computer linked to the FP-2000:

deploying NI_AALPro.lvlib 
Deploying NI_AALPro.lvlib:General Polynomial Fit.vi
Failed to download NI_AALPro.lvlib:General Polynomial Fit.vi
LabVIEW:  Failed to load shared library lvanlys.dll:PolyFit81_head:C on RT target device.

Basically the same failiure.  Any other ideas?  Isn't there a minimized RT math set? 

Thanks,

Bill

I thought I would try a few of the other advanced math vis, dot product, statistical mean, and a few others all fail with similar errors.  I don't think this is related to FP-2000 software corruption. 

Thanks,

Bill
