The circuit diagram which Pico contains may not be completed or the system or
machine may be in a state which Pico is not permitted to control. The outputs
should not be activated when Pico is powered on.
Setting the Start-Up Behavior
The 1760-L12AWA-ND model can only be started in Run mode.

available until Pico is unlocked (see the section Unlocking Pico on page 6-3).

RUN/STOP is a toggle menu. The menu always displays the operating mode into
which you can change.
The default setting for Pico is for STOP MODE to be displayed. In other words,
Pico starts in Run mode when the power is applied.

diagram is deleted this does not result in the loss of the setting selected.

Downloading
When a valid circuit diagram is transferred from Pico to a memory module or the
PC or vice versa, the setting is still retained.
