These indicator lights are governed by
the control system. Their state is
determined entirely by the application
program of the control system
governing the display unit. As a result,
their role can vary from application to
application:
- Signaling linked to the key
(same type of role as the system LEDs
above)
- Signaling the status or a fault
of the component governed by the key
