4.2 Working with contacts and relays
In easy circuit diagrams, the switches, buttons and relays of conventional
circuit diagrams are connected up using input contacts and relay coils.
4.2.1 Input and output contacts
First specify which input and output terminals you wish to use in your circuit.
Depending on the type and configuration, easy has 8, 12 or 24 input
terminals and 4, 6, 8, 10 or 16 outputs. The signal states at the input
terminals are evaluated in the circuit diagram with the input contacts I1 to
I12. R1 to R12 are input contacts of the expansion. The outputs are
connected in the circuit diagram with the output relays Q1 to Q8 or S1 to S8
(expansion).
4.2.1.1 Entering and changing contacts and relay coils
A switch contact is selected in easy via the contact name and contact
number.
A relay coil is defined by its coil function, name and number.
Values for contacts and coil fields are changed in Entry mode. The value to
be changed flashes.
