3.11 Configuration and Operating Mode of the LED Indicators
(Function Group LED)
The P634 has 23 LED indicators for the indication of binary signals. Some of the
LED indicators are permanently assigned to fixed functions. The other LED
indicators are freely configurable. These freely configurable LEDs will emit either
red or green or amber light (amber is made up of red and green light and may
not be configured independently).
3.11.1 Configuring the LED Indicators
One binary signal can be assigned to each of the red and green LED color
indications. The same binary signal can be assigned to several LED indicators (or
colors), if required.
