FPGA Resampling VI

[IMSS]

Buenos dias.

 Tengo una aplicacion en la que la frecuencia de red va a ser variable entre 30Hz y 60Hz. En el programa de Labiew que tenemos utilizamos en la FPGA el vi FPGA resampling que veo que esta diseñado para 50Hz o 60Hz. Mi pregunta son. Esta vi con esta frecuencia de red diferente a 50Hz o 60Hz no funcionara, no?

¿Existe alguna vi donde por medido de alguna variable le pueda decir yo que frecuencia de red tengo?

See https://www.ni.com/docs/en-US/bundle/flexrio-api-ref/page/flexrio-api-ref/flexriointegratedmerge/idl...

Look for decimation and interpolation VIs.  This needs the FlexRIO driver to be installed.

hi Terry. 

Thanks for your answer.

But we continue without understanding

Inside this block we saw if it is 50hz o 60 hz the different is this cte values

Two questions.

      What are this constants values?

      If we change these constants depending on supply frequency it will be work properly?

[Terry_ALE]

I am not familiar with these specific VIs.

Interpolation typically has some filtering.  I would imagine these are coefficients or constants to support that.

Which toolkit are these VIs from?  Electric Power?

Hola Terry

 Correct it is from power electric toolkit.

In our application, now the electric supply can be between 40Hz and 60Hz and my doubt is how we can adapt it to work in this range.

Thanks

Is it required to use FPGA resampling? The FPGA resampling is fixed to 50/60 Hz system. I would recommend to use the Host Resampling for your case which shouldb be more flexible.

Hola Yifan.

  Gracias por la ayuda.

Soy nuevo en este tema y no termino de enterder una cosa. ¿Que hace exactamente la funcion resampling?

¿cual seria la diferencia si uso la que me aconsejas host resampling?

Gracias
