Circuit diagram display
The circuit diagram display is currently empty. The cursor
flashes at the top left, which is where you will start to create
your diagram.
The location of the cursor is indicated in the status line. L: =
Rung (line), C: = Contact or coil (contact), B: = Free memory
available in bytes. Start value 7944, with the first three rungs
already generated.
The EZD circuit diagram supports 4 contacts and one coil in
series. The EZD display can display 6 circuit diagram contact
fields.
Use the
Í Ú ú í
cursor buttons to move the cursor over the
invisible circuit diagram grid.
The first four columns are contact fields, the fifth column is a
coil field. Each line is a rung. EZD automatically connects the
contact to the power supply.

Now try to wire up the following EZD diagram.
Switches S1 and S2 are at the input.
I 01
and
I 02
are the
contacts for the input terminals. Relay K1 is represented by
the relay coil
Ä Q 01
. The symbol
Ä
identifies the coil's
function, in this case a relay coil acting as a contactor.
Q 01
is one of the EZD output relays.
