Labview RT/FPGA Compling Error with NI_DigFilterLicensed.lvlib

[chefweb]

Hi,

I'm trying to compile a program for my sbRIO-9632 but I got following error:

Deploying NI_DigFilterLicensed.lvlib:dfd_Filter Signal by Coef.viNI_DigFilterLicensed.lvlib:dfd_Filter Signal by Coef.vi loaded with errors on the target and was closed.
LabVIEW:  Failed to load shared library LVDFD.*:NormFltH:C on RT target device.

Is this filter not compatibel to Labview RT?

I'm using Labview 2009SP1, FPGA SP1, RT, SP1 and NI-RIO 3.4.

Many thanks

As stated above you need Digital Filter Design Toolkit (DFD) installed on your sbRIO target.

Hi,

many thanks for your help. That could be the solution but how can I add the digital filter toolkit to the sbRIO? I can't choose the package to install it on the sbrio.

Many Thanks

Hello chefweb,

make sure you have Digital Filter Design Toolkit installed and properly activated, then follow the screenshots below in your Measurement & Automation Explorer (MAX):

Just got stuck on this issue for a while until I found your post. Why is the digital filter toolkit option not present in the standard software sets? I am running LabVIEW 2012 and RIO 12.0.

Hello,

I encounter exactly the same problem with the Digital Filter Design Toolkit. However I use Labview 2016.0f5, Ni CompactRIO 19.6 and a cRIO9030 (Linux).

The Digital Filter Design Toolkit is correctly installed and licensed on the development PC:

Unfortunately I can't find the Digital Filter Design Toolkit in the custom software installation part of MAX as described by ecalator in 2010.

Any suggestions how I could fix this missing component ?

Is there a compatibility issue with the Filter Design Toolkit and the cRIO 9030 ?

Best Regards

Boris

Hello,

Unfortunately the Digital Filter Design Toolkit is not compatible with the Ni Linux Real-Time (Intel x64 based) systems ! This seems to be the reason why I can't install this toolkit on the cRIO9030.

This information can be found in the 2016 Digital Filter Design Toolkit readme:
