Input function
All inputs work the same way: When the LHMI is configured so that a certain function
button is of type CONTROL, then the corresponding input on this function block becomes
active, and will light the yellow function button LED when high. This functionality is
active even if the function block operation setting is set to off.
There is an exception for the optional extension EXT1 function keys 7 and 8, since they
are tri-color (they can be red, yellow or green). Each of these LEDs are controlled by three
inputs, which are prioritized in the following order: Red - Yellow - Green
