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.
