The following coil functions are available for all coils:
Table 13: Coil function
The usable coil functions of the function blocks are described in the relevant
chapter (￫ Chapter 5, “Function blocks“, page 135).
Coil with contactor function Ä
The output signal follows the input signal directly, the relay operates as a
contactor.
Figure 84:Contactor function signal diagram
Coil with the impulse relay function ä
The relay coil switches whenever the input signal changes from 0 to 1.
The relay behaves like a bistable flip-flop.

With non-retentive coil functions such as Ä (contactor),
Å (negated contactor), È, è (rising and falling edge evaluation):
Each coil must only be used once. The last coil in the circuit
diagram determines the state of the relay. Exception: When
working with jumps, the same coil can be used twice.
Retentive coil functions such as S, R, ä can be used several
times.
