Greyed-out Butterworth filter express VI icon in FPGA module

[vpezzul]

Hi, I am trying to use the Butterworth filter express VI in the fpga module. When I place the icon in my VI it takes a while to load and then when it finally comes up, it is shaded or greyed out and there are no terminals to connect to on the icon (see the screenshot below). I have been searching around for help and there seems to be no other similar situation to mine out there.  I'm simply trying to read analog signals from a NI-9215 AI module and filter them with a low pass Butterworth filter to then read them in a real-time VI and display them. If anyone knows how to fix this or if there is another step I'm missing I would appreciate your help!

A quick peek into the help for the function would be advisable.

You can't use that function on the FPGA target- if you try the Compiler breaks your code.

 

The VI only generates coeffients for a filter and does no filering itself.  Use it to pass filter parameters into the FPGA filter

Looks like the Express VI Located at 'Programming->FPGA Math & Analysis->Butterworth Filter' to me...

Its greyed out becuase it can't find the VI I assume... is it the same if you drop a new one? If so, I'd try a repair of the FPGA Module. Sounds like a bad install to me... Please make sure you have full admin rights on the PC when you're doing installations and repairs.

Let us know how that goes!
