Sine wave genaration on FPGA

Hi all,

I've a problem during the sinewave geneartion on cRIO via FPGA with NI9246 module.
I've used the same LV structure found in LV example folder ( Hardware Input and Output->CompactRIO->Signal generation and Processing->Analog->Sine Wave) and adapted at my porject (based on LVOO and actor framework).
I'm anle to generate a signal with right frequency and amplitude but regarding the shape no!!!...I generate a square wave.
I attach the jpg of real time part and the fpga impementation, due to the complexity of the project i can not upload all files.
The cRIO module works with a FXP (int word lenghts 5 bits and word lenght 16, signed)

Any suggestion?
Thanks
