5.4 Working with contacts and coils
Switches, pushbuttons and relays from a conventional hardwired circuit diagram are
wired in the easyE4 circuit diagram via input contacts and relay coils.
Hardwired
Wired with an easyE4 device
easyE4 connection
Make contact S1 to input terminal I1
Make contact S2 to input terminal I2
Connect load E1 to easy output Q1
S1 or S2 switch on E1.

First specify which input and output terminals you wish to use in your circuit.
The signal states on the input terminals are detected in the circuit diagram with the
input contacts I, R or RN. The outputs are switched in the circuit diagram with the out-
put relays Q, S or SN.
The jump destination has a special position for the input contacts and the jump location
for the output relays. These are used for structuring a circuit diagram → Section "Work-
ing with contacts and coils", page 133.
Following is a description of how to wire various contacts and coils for the various
relay types and function blocks (inputs) in the circuit diagram.
