Limit Axis CNC Jerk using SMC_Polynomial_AbsMaxLocs

Dears.

Until now, I have been using CNC libraries with Codesys 3.5SP11. I was using SMC_Polynomial_AbsMaxLocs function, from CNC library, to calculate the axis jerks, interpolating splines, to limit it.

Now I have passed to SP20, and the functions which calculates the zeros and the maximum-minimum and zeros of polynomials has been disapeared.

Questions:

-Exist any FB wich can limit the jerk of individual axis in CNC?
-Exist any other functions which can calculate max-min and zeros of polynomials?

Thanks
