Function
When the input is ON, this instruction finds the function value
f(x)
for
A as
x
, and stores it in
C. The
function
f(x)
is defined by the parameters stored in 2

Example
When R010 is ON, the FG instruction finds the function value
f(x)
for
x
= XW004, and stores the
result in D0100.
The function
f(x)
is defined by 2
´
4 = 8 parameters stored in D0600 to D0607. In this example,
these parameters are set at the first scan.
