These LEDs are governed by the automation
system. Their state is determined entirely by the
application program of the automation system
governing the terminal. As a result, their role can vary
from application to application:
z Signaling linked to the key (same type of role as
the system LEDs above)
z Signaling the status or a condition of the
component governed by the key
