Contacts
Contacts are used to change the power flow inside the
easySafety circuit diagram. Contacts such as make contacts
are set to 1 when they are closed and 0 when they are
opened. In the easySafety circuit diagram you can wire
contacts as make or break contacts.
An easySafety device operates with different contacts that
you arrange in any order in the contact fields of the safety or
standard circuit diagram.

Usable contacts
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. Coils can have seven different coil
functions which is explained in greater detail on page 145.
A easySafety device is provided with different types of relays
and function blocks which can be wired in a circuit diagram
via their coils (inputs).
The switching of the relays is set by means of coil functions
and parameters.
