5. Programming on the device
5.3 Circuit diagram elements
5.3.4 Coils
Coils are the actuating mechanisms of relays. The results of the wiring are transferred
to the coils when the device is in RUN mode. These switch to the On (1) or Off (0) state
according to these results. The options for setting output and marker relays are listed
with the description of each coil function.
A easyE4 device is provided with different types of relays and function blocks which
can be wired in a circuit diagram via their coils (inputs).
Coil functions
You can set the switching behavior of these relays by means of the coil functions and
parameters selected.
If you want to map coils from your circuit diagram to the
easyE4 device, use the coils with a contactor function in your
device!
The following coil functions are available for all coils:

Table 55: Coil function
With non-retentive coil functions such as
(contactor),
(negated contactor),
(rising) and
(falling edge eval-
uation): Each coil must only be used once. The last coil in the circuit dia-
gram 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
,
can be used several times.
The available coil functions for the various function blocks are described in the relevant
sections. Please refer to → Section "Working with function blocks", page 154
