4.1.2.6 Contacts
You modify the power flow with the contacts in the easy circuit diagram.
Contacts such as N/O contacts are set to 1 when they are closed and 0 when
they are opened. Every contact in the easy circuit diagram can be defined as
either an N/O contact or an N/C contact.
4.1.2.7 Coils
Coils are the actuating mechanisms of relays. In RUN mode, the results of
the wiring are sent to the coils, which switch on or off accordingly. Coils can
have seven different coil functions.
Table 6: Usable contacts
Easy works with different contacts, which can be used in any order in the
contact fields of the circuit diagram.

￫
To ensure compatibility with easy400 and easy600 devices,
each easy500 and easy700 is provided logically with all possible
contacts. The switching state is always zero if contacts are not
supported by the device, i.e.
• devices without a clock. The contacts (N/O contact) of the
time switches are always set to logic 0.
The advantage of this process is that you can use the same
circuit diagram on all easy500, easy700, easy-AB, easy-AC,
easy-DA and easy-DC devices.
