Draw a Circuit Diagram with Pico 4-13
The Status menu display shows whether the P-Buttons are used in the
circuit diagram.
Check the Circuit Diagram
Pico allows you to monitor the switching states of contacts and relay
coils during operation.
1. Complete the small parallel connection and switch Pico to Run
mode via the main menu.
2. Return to the circuit diagram display.
You are now unable to edit the circuit diagram.
The circuit diagram display performs two functions depending on the
mode:
• STOP: Create circuit diagrams
• RUN: Show power flow display
Switch on I3.
In the power flow display, current-carrying connections are thicker
than those that are not powered.
You can follow a current-carrying connection across all circuit
connections by scrolling the display up and down. The power flow
display will not show signal fluctuations in the millisecond range. This
is due to the inherent delay factor of LCD displays.

If you switch to the circuit diagram display and are
