Starting Point: Status Display
When you power up the unit, it opens the status display immediately to show the
state of the inputs and outputs. It also indicates whether Pico is already running a
program.
Press Ok to switch to the main menu.
You can then press Ok to move forward to the next menu level or Esc to go back
one level. Ok has two other functions:
• Press Ok to save modified settings.
• Press Ok to insert and modify contacts and relay coils. In this case, Pico must
be in Stop mode.
Press Ok three times to enter the circuit diagram display from the status display.
This is where you create the circuit diagram.
Circuit Diagram Display
The circuit diagram display is currently empty. The
cursor is flashing at the top left, which is where you start
to create your program.
Move the cursor, using the cursor buttons, across the
hidden grid lines
The first three double columns are contact fields and the
right-hand triple column forms the coil field. Each line is
a circuit connection. Pico adds the first contact
automatically.
Now try to program the following Pico circuit diagram.
Switches S1 and S2 are wired to input I1 and I2. Relay K1
is represented by the relay coil {Q1. The symbol “{”
identifies the coil's function, in this case a relay coil acting
as a contactor. Q1 is one of up to six Pico output relays.
