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: = Circuit
connection (line), C: = Contact or coil (contact), B: = Free memory available
in bytes. Start value 7944, with the first three circuit connections already
generated.
The Pico GFX-70 circuit diagram supports 4 contacts and one coil in series.
The Pico GFX-70 display can display 6 circuit diagram contact fields.
Use the up, down, left and right arrow 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 circuit connection. Pico GFX-70 automatically connects the contact to
the power supply.
Figure 3.3 Circuit diagram with inputs I1, I2 and output Q1
Now try to wire up the following Pico GFX-70 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
[ Q 01
. The symbol
[
identifies the coil's function, in this case a relay coil acting as a contactor.
Q 01
is one of the Pico GFX-70 output relays.
