4.2 Working with contacts and relays
4.2.6.3 Contactor function with negated result (inverse contactor function)
4.2.6.4 Falling edge evaluation (cycle pulse)
74
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.

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.
