Wire Inside of Your Program
Pico displays a small arrow when creating a circuit connection.
Pressing Alt activates the arrow and the cursor buttons to move it. Alt
also has two other functions:
• From the left contact field, press Alt to insert a new, empty
circuit connection (rung).
• Press Alt to set the contact currently under the cursor to either a
make or break contact.
The wiring arrow works between contacts and relays. When you
move the arrow onto a contact or relay coil, it changes back to the
cursor and can be reactivated with Alt if required. Pico automatically
wires adjacent contacts in a circuit connection up to the coil.
1. Press Alt to wire the cursor from I2 through to the coil field.
The cursor changes into a flashing wiring arrow and
automatically jumps to the next possible wiring position.
2. Press the right cursor button.
Contact I2 is connected up to the coil field. Use the Del button
to delete wiring at the cursor or arrow position. Where
connections intersect, the vertical connections are deleted first,
then, if you press Del again, the horizontal connections are
deleted.
3. Press the right cursor button again.
The cursor will move to the coil field.
4. Press Ok.
Pico inserts relay coil Q1. The specified coil
function ’
{
’ and the output relay Q1 are
correct and do not have to be changed.
Your first working Pico circuit diagram now
looks like this:
5. Press Ok. Then press Esc to leave the circuit
diagram display. The diagram will be
automatically saved.
Once you have connected buttons S1 and
S2, you can test your circuit diagram.
