Mode 2 (PULSED)
In this mode the output will be high for as long as the setting pulse time. After this
time the output will go back to 0. The input attribute is reset when the function
block detects it being high and there is no output pulse.
Note that the third positive edge on the input attribute does not cause a pulse, since
the edge was applied during pulse output. A new pulse can only begin when the
output is zero; else the trigger edge is lost.

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
