4.4.2 Relays
Relays are switching devices that are emulated in easy800 device
electronically, which activate their contacts according to the assigned
function. A relay consists of at least one coil and contact.
4.4.3 Contacts
Contacts are used to change the power flow inside the easy800 circuit
diagram. Contacts such as N/O contacts are set to 1 when they are closed
and 0 when they are opened. In the easy800 circuit diagram you can wire
contacts as make or break contacts. N/C contacts are indicated with a
horizontal line above the operand concerned.
An easy800 device operates with different contacts that you arrange in any
order in the contact fields of the circuit diagram.
Table 12: Usable contacts
4.4.4 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. The options for setting
output and marker relays are listed with the description of each coil function.
A easy800 device is provided with different types of relays and function
blocks which can be wired in a circuit diagram via their coils (inputs).
Coil Functions
The switching of the relays is set by means of coil functions and parameters.

If you wish to map coils from your circuit diagram in the
easy800 device, use the coils with the Contactor coil function in
your device!
