A function block has set of input and output signals.
A function block can contain more signals than needed in that application part. A
signal that is not used in a particular application is possible to hide in the function
block view in ACT. It is not necessary to connect all inputs and outputs at a
function block. If not connected, the signals always have a default value. The
default value can be seen when hove over the signal with the mouse.
Signals are located on both sides of the middle position up and down. When there
is space left, move some signals up or down for a better visibility and connection
routing.
