5.3 Circuit diagram elements
5.3.3 Contacts
Contacts are used to change the power flow inside the easyE4 circuit diagram.
Contacts such as N/O contacts are set to 1 when they are closed and 0 when they are
opened. In the easyE4 circuit diagram you can wire contacts as make or break con-
tacts. N/C contacts are indicated with a horizontal line above the operand concerned.
An easyE4 device operates with different contacts that you arrange in any order in the
contact fields of the circuit diagram.
