Malfunctioning of WA Wavelet Filter VI when used with cRIO9082

[ijaz]

I hope you are doing well. I am working on the Wavelet Transform, the following VI is creating problems when used with the real time systems.

WA Wavelet Filter VI

It reads filter coefficients when enabled 'Read from file' option offline. But when I try to use the same program in NI-cRIO9082- it does not not pop up any window to read filter coefficients and gives '0' output. 

Please let me know how I can read filter coefficients saved in a file while working on the real time systems.

Hello Ijaz,

The reason why you’re seeing this behavior is because the WA Wavelet Filter VI is not supported in the LabVIEW Real-Time Module, as explained in the LabVIEW Help. As for reading filter coefficients, you can store a file in the controller and call it from your block diagram, just remember to use the correct file path.
