3.4.0.1 Starting point: Status display
easy activates the status display after it is powered up. The status display
indicates the switching state of the inputs and outputs and whether easy is

▶ Press OK to switch to the main menu.
Press OK to switch to the next menu level, and press ESC to move one level
back.
In this case easy must be in STOP mode.
▶ Press OK 2 × to enter the circuit diagram display via menu items

diagram.
3.4.1 Circuit diagram display
The circuit diagram display is currently empty. The cursor flashes at the top
left, which is where you will start to wire your circuit diagram. easy will
automatically propose the first contact
I1.
Use the ÍÚ
úí cursor buttons to move the cursor over the invisible circuit
diagram grid.
The first three double columns are the contact fields and the right-hand
columns form the coil field. Each line is a rung. easy automatically energizes
the first contact to voltage.
▶ Now try to wire up the following easy circuit diagram.
The switches
I1 and I2 are at the input whilst I1 and I2 are the contacts for
the input terminals. Relay K1 is represented by the relay coil
ÄQ1. The symbol
Ä identifies the coil's function, in this case a relay coil acting as a contactor.
Q1 is one of up to eight easy output relays in the basic unit.
