The status of the input or output can be read from the relevant yellow LED:
The LEDs of the I/O function area are electrically located in the logic area.
This may mean that the LED of an output is on but the output cannot be controlled due to
an error between the logic area and the digital output. The LED does not monitor the
output state. In the event of an error, the actual output state may differ from the state
indicated by the LED.
