5) After backup, close the original PLC program. Then click on File to Open the PLC
interface program (*.fp) you wish to update as shown in the figure below.

LED
DESCRIPTION
RUN (green)
This is lit in the RUN mode, to indicate that the program is being
executed. It flashes during forced input/output.
PROG. (green)
This is lit in the PROG. mode. Operation stops while this LED is lit. It
flashes when waiting for connection of slave station on remote I/O
system. If the memory is initialized, the brightness dims, indicating that
initialization is being executed.
TEST (green)
This si lit in the test operation mode.
BREAK (green)
This is lit in the operation halts at a break during a test run or halts during
the step operation mode for the test run.
ERROR (red)
This is lit if an error is detected during the self-diagnostic function.
BATT. (red)
This is lit when the voltage of the backup battery drops below a specific
value.
ALARM (red)
This is lit if a hardware error occurs, or if operation slows because of the
program, and the watchdog timer is activated.

POSITION
OPERATION MODE
INITIALIZE (up)
In the PROG. mode:
The contents of the operation memory are initialized. However, the
system register (including the I/O map) and the program are not
initialized. If the error of self-diagnostic error code 42 or lower is
occurred, the special internal relays R9000 to R9008 and the special
data register DT90000 are not cleared.
In the RUN mode:
Operation errors, remote I/O system errors, and battery errors are
cleared.
(center)
The switch should normally be left in this position.
TEST (down)
Setting this switch to the downward position in the PROG. mode,
accesses the TEST mode. Switching to the RUN mode in this status,
initiates test operation.
To return from the TEST mode to normal operation, return this switch to
the center position in the PROG. mode.

POSITION
OPERATION MODE
RUN (up)
This sets the RUN mode. The program is executed, and operation
begins.
REMOTE (center)
This enables operation to be started and stopped from a programming
tool. At the stage where the selector is changed, when switching from
the PROG. to the REMOTE mode, the system remains in the PROG.
mode and when switching from RUN mode to the REMOTE mode, it
remains in the RUN mode.
PROG. (down)
This sets the PROG. mode. In this mode, programming can be done
using tools, the test operation mode can be accessed and the
operation memory can be initialized using the initialize/test switch.
