4.2.6.3 Contactor function with negated result (inverse contactor function)
Å
The output signal is simply an inversion of the input signal; the relay operates
like a contactor with contacts that have been negated. If the coil is triggered
with the state 1, the coil switches its N/O contacts to the state 0.

4.2.6.4 Falling edge evaluation (cycle pulse)
è
This function is used if the coil is only meant to switch on a falling edge. With
a drop-out in the coil state from 1 to 0, the coil switches its N/O contacts to
the 1 state for one cycle.

Physical outputs should not be used as a cycle pulse is
generated.
