6.1.2. Basic Functions List – GF
Basic functions represent simple logical elements of
Boolean algebra.
You can invert the inputs of individual basic functions, i.e.
The circuit program inverts a logical “1” at a relevant input
to a logical “0”; if “0” is set at the input, the program sets a
logical “1” and vice versa.
The GF list contains the basic function blocks you can use
for your circuit program. The following basic functions are
available:

Description of function
The output of an AND function is only 1 if all inputs are 1,
i.e. when they are closed.
A block input that is not used (x) is assigned: x = 1.
