Breakpoint 0 (A0/B0 = p20374[0]/p20375[0]) ... Breakpoint 19 (A19/B19 = p20374[19]/p20375[19])

Note:
This function block randomly adapts output variable Y to input variable X by means of up to 20 breakpoints in 4
quadrants.
Interpolation is carried out linearly between the breakpoints. Outlying the area A0 to A19, the characteristic curve runs horizontally.
During configuration, you must ensure that the values of A0 to A19 are arranged in ascending order. Otherwise the
values at the output will not be correct. The values B0 to B19 can be selected at random, i.e., independently of the
previous value.
If breakpoints are not needed (e.g., A16/B16 and higher), the following values of the X- and Y-coordinates (A16/B16 to
A19/B19) must be assigned the same values as A15/B15.
