Remember that the spreadsheet makes many assumptions about how you will use a
the various blocks. So your CALCA block in your CP60 may not use the same %cpu
that the CP60 spreadsheet determines. But it is a good starting point and "in
general" if the spreadsheet does not show an overload, it is highly likely that
your CP60 will not overload. BUT.....
MATH block assumption is that you are using the maximum 20 steps. The CALC
(and the CALCA) assumption is that you are using 15 steps. If you use IND
blocks you may wish to take a look at those assumptions.

Objet : [foxboro] MATH vs CALCA loading
I was perusing the CP60 loading spreadsheet and it appears that a MATH
block takes more processing than a CALCA. is this correct and why?
anyone know?
