Modes of Operation

Pico has two operating modes: Run and Stop.

In Run mode, the unit continuously processes a stored program or
circuit diagram until you select Stop or disconnect the power. The
circuit diagram, parameters, and settings are retained in the event of a
power failure. If the back-up time has elapsed after a power failure,
you will need to reset the real-time clock. Circuit diagram entry is only
possible in Stop mode.

In models with an LCD display, a circuit diagram inside an installed
memory module is not run automatically. The circuit diagram must
first be transferred from the memory module to the unit.

In Run mode, the 1760-L12xxx-ND and 1760-L18xxx-xxND load the
circuit diagram from the memory module automatically and run it
immediately.

ATTENTION

In Run mode, Pico immediately runs the circuit
diagram saved in the unit when the incoming power
is turned on. This happens unless Stop mode was set
as start-up mode. In Run mode, outputs are activated
according to the program.
