PtByPt Filter: can't change parameters dynamically

[Pavel_47]

Hello,

In my VI I use PtByPt Low-Pass filter.

Surprisingly, the filter parameters (e.g. cutoff frequency, order) cannot be change dynamically ... i.e. when VI is running.

I order to new parameters be taken into account I should restart VI.

Is it correct behavior for PtByPt filter ?

Thanks.

After changing the parameters, did you set the 'initalise?' to true so the VI can reinitialise?

You mean "initialize" input of filter ?

Ok, I see.

Actually I've put button and it works: parameter are taken into account after button action.

But it's not very comfortably, I will try process it in the event loop.
