Station parameter ► Falcon series ► Keyboard field ► LED-Bit field
All function key LEDs are allocated specific addresses. The LED functions are controlled by setting the defined bits. The following functions can be controlled via the LED bit area:
If two different LED functions are activated simultaneously, the highest priority is assigned to the function "Flashing", "Flashing rapidly" has a medium priority and "Statically On" has the lowest priority.
Furthermore, the LED bit area provides you with a static control word and a dynamic control word used to parametrize different settings of the operator interface.
