5. Programming on the device5.3 Circuit diagram elements5.3.4 CoilsCoils are the actuating mechanisms of relays. The results of the wiring are transferredto the coils when the device is in RUN mode. These switch to the On (1) or Off (0) stateaccording to these results. The options for setting output and marker relays are listedwith the description of each coil function.A easyE4 device is provided with different types of relays and function blocks whichcan be wired in a circuit diagram via their coils (inputs).Coil functionsYou can set the switching behavior of these relays by means of the coil functions andparameters selected.If you want to map coils from your circuit diagram to theeasyE4 device, use the coils with a contactor function in yourdevice!The following coil functions are available for all coils:Display Coil function Example ￫ PageContactor function Q01, D02, S04, :01, M07,.. → page 127Impulse relay func-tion Q03, M04, D08, S07, :01,.. → page 127S Set SQ08,SM02,SD03,SS04.. → page 128R Reset RQ04,RM05,RD07,RS03.. → page 128Contactor functionwithnegated resultQ04, M96.. → page 129Cycle pulseon rising edge M01.. → page 129Cycle pulseon falling edge M42.. → page 130Table 55: Coil functionWith 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 withjumps, the same coil can be used twice.Retentive coil functions such asS, R, can be used several times.The available coil functions for the various function blocks are described in the relevantsections.
