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 field (contact),
B: = Number of free memory locations in bytes.
Start value 7944, with the first three circuit connections
already generated.
The display system circuit diagram supports 4 contacts and
one coil in series. The display system can show 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 represents a rung. The display system
automatically connects the contact to the power supply.

X Now try to wire up the following display system circuit
diagram.
The switches S1 and S2 are at the input whilst
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
. Q01 is one of the display system output
relays.
