Step 5: After backup, close the original PLC program. Then click on File to Open the HCI

interface program (*.fp) you wish to update as shown in the figure below.

Select the program file to use for update (*.fp)

Step 6: Click on the icon in the menu (Download to PLC), click Yes to confirm overwrite of

existing program as shown in the picture below:

Step 7: Wait for the PC to transfer the data to the PLC, and the program will be updated.

1.6 PLC Hardware Overview

1.6.1 CPU(FP2-C1) Unit

1.6.1.1 Status indicator LEDs

LED Description

RUN (green) This lights in the RUN mode, to indicate that the program is

begin executed. It flashes during forced input/output.

PROG. (green)

This lights in the PROG. mode. Operation stops while this LED

is lighted. 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 lights in the test operation mode.

BREAK

(green)

This lights 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 lights if an error is detected during the self-diagnostic

function.

BATT. (red)

This lights when the voltage of the backup battery drops below

a specific value.

ALARM (red) This lights if a hardware error occurs, or if operation slows

because of the program, and the watchdog timer is activated.

1.6.1.2 Initialize/Test Switch

Switch

position

Operation mode

INITIALIZE

(upward)

In the PROG. mode:

The contents of the operatio

n 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

(downward)

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 the normal operation, return

this switch to the center position in the PROG. mode.

1.6.1.3 Mode Selector

Selector position

Operation mode

RUN (upward) 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.

(downward)

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.
