Function description
AND function block
Functionality
The AND function is used to form general combinatory expressions with boolean
variables. The AND function block has four inputs and two outputs.
Default value on all four inputs are logical 1 which makes it possible for the user to just
use the required number of inputs and leave the rest un-connected. The output OUT has
a default value 0 initially, which suppresses one cycle pulse if the function has been put in
the wrong execution order.
