4.5 Operation mode
Operation mode defines operation status, program execution of LP-S044.
You can change mode by switch of LP, or remote control in SmartStudio. Be sure that when
mode is change, inner device and special device status are changed.
LP-S044 has four kinds of operation mode; RUN, STOP, PAUSE, and DEBUG mode.

RUN mode
It saves external contact status to inner memory and executes the operations such as step
order, branch instruction, or interrupt until END line. After this, it outputs repeatedly output
device memory value as external output signal.

STOP mode
It stops user defined program execution.
At the same time, it initializes inner memory data (except latch area, parts of special device)
and makes every external output signal turn OFF to turn OFF external output signals by
program.

PAUSE mode
It stops only user defined program execution.
It maintains inner memory and external output signal.

DEBUG mode
It is waiting status for executing debug instruction by stopping user defined program at 0
step. At the same time, it initializes inner memory data (except latch area, parts of special
device) and makes every external output signal turn OFF.
