Input function
All function keys 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. It has
been implemented this way for safety reasons; the idea is that the function key LEDs
should always reflect the actual status of any primary equipment monitored by these
LEDs.
