Wiring 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.

press Del again, the horizontal connections are deleted.
