Note!
If you have a program step in the SFC like the following
and if you use 68xxx generators, please note the following: The allocation of the
value of the second input variable at the AND operator module to variable z will not
be executed ! This is due to the optmized processing in the SFC in case of value
FALSE at the input variable.
