Start 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. If there is an expansion module
installed, the expansion module status screen is displayed. Press Ok
again 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 two times (3 times with an expansion module installed) to
enter the circuit diagram display from the status display(s). This is
where you create the circuit diagram.
