Coil negation (inverse contactor function) Å
The output signal is simply an inversion of the input signal;
the relay operates like a contactor whose contacts have been
negated. If the coil is triggered with the 1 state, the coil
switches its make contacts to the 0 state.

Rising edge evaluation (cycle pulse) È
If the coil is only meant to switch on a rising edge, this
function will be applied. With a change in the coil state from
0 to 1, the coil switches its make contacts to the 1 state for
one cycle.

Falling edge evaluation (cycle pulse) è
If the coil is only meant to switch on a falling edge, this
function will be applied. With a change in the coil state from
1 to 0, the coil switches its make contacts to the 1 state for
one cycle.
