Table 4 Functions vs. LED Illumination Options.
Note:
Regarding the LEDs, it is interesting to distinguish the following cases:
Disabled button: the LED will remain off, and the button will have no function.
Button configured as “Individual” with “LED Indicator” function: the button will
still have no function. The LED may be turned on/off through a binary object.
Button configured as any other control type: the behaviour of the LED will be
configurable according to the following table (being also possible to leave it
turned off).
