Safety Precautions
: Incorrect handling of the device may result in minor injury or physical damage.
Be sure to read the "Safety Precautions" thoroughly before using the module.
Here, the safety precautions items are classied into "Warning" and "Caution".
Warning
: Incorrect handling of the device may result in death or serious injury.
Caution
Even some items indicated by "Caution" may result in a serious accident.
Both safety instruction categories provide important information. Be sure to strictly observe these instructions.
Warning
Neve touch any part of charged circuits as terminals and exposed metal portion while the power is turned ON.
It may result in an electric shock to the operator.
Turn OFF the power before mounting, dismounting, wiring, maintaining or checking, otherwise, electric shock, erratic
operation or troubles might occur.
Place the emergency stop circuit, interlock circuit or the like for safety outside the PLC. A failure of the PLC might break
or cause problems to the machine.
When using an expansion right side unit, be sure to mount a healthy unit to stop the SPF system with a fatal fault if the
expansion right side unit is dropped. Unless a healthy unit is mounted, a dropout of the expansion right side unit is not
detected and the SPF system continues operation in the state where the expansion right side unit is dropped.
Safety Precautions
Caution
Do not use one found damaged or deformed when unpacked, otherwise, fire, failure or erratic operation might be caused.
Do not shock the product by dropping or tipping it over, otherwise, it might be damaged or troubled.
Follow the directions of the instruction manual and user’s manual when mounting the product.
If mounting is improper, the product might drop or develop problems or erratic operations.
Use the rated voltage and current mentioned in the instruction manual and user’s manual. Use beyond the rated values
might cause fire, erratic operation or failure.
Operate (keep) in the environment specified in the instruction manual and user’s manual. High temperature, high humidity,
condensation, dust, corrosive gases, oil, organic solvents, excessive vibration or shock, might cause electric shock, fire,
erratic operation or failure.
Select a wire size to suit the applied voltage and carrying current. Tighten the wire terminals to the specified torque.
Inappropriate wiring or tightening might cause fire, malfunction, failure or might cause the product to drop from its
mounting.
Contaminants, wiring chips, iron powder or other foreign matter must not enter the device when installing it, otherwise, fire,
accident, erratic operation or failure might occur.
Remove the dust-cover seals of modules after wiring, otherwise, fire, accident, erratic operation or failure might occur.
Connect the ground terminal to the ground, otherwise, electric shock or erratic operation might occur.
Periodically make sure the terminal screws and mounting screws are securely tightened.
Operation at a loosened status might cause fire or erratic operation.
Put the furnished connector covers on unused connectors, otherwise, erratic operation or failure might occur.
Sufficiently make sure of safety before program change, forced output, starting, stopping or anything else during a run.
Wrong operation might break or cause problems to the machine
Engage the loader connector in a correct orientation, otherwise, an erratic operation might occur.
Before touching the PLC, discharge any static electricity that may have been collected on your body. To discharge it, touch
a grounded metallic object. Static electricity might cause erratic operation or failure.
Be sure to install the electrical wiring correctly and securely, observing the directions of the instruction manual and user’s
manual. Wrong or loose wiring might cause fire, accident or failure.
When disengaging the plug from the outlet, do not pull the cord, otherwiase, break of cable might cause fire or failure.
Do not attempt to change system configurations (such as installing or removing expansion block) while the power is ON,
otherwise, failure or erratic operation might occur.
Do not attempt to repair the module by yourself, but contact your Fuji Electric agent, otherwise, fire, accident or failure
might occur.
To clean the module, turn power off and wipe the module with a cloth moistened with warm water. Do not use thinner or
other organic solvents, as the module surface might become deformed or discolored.
Do not remodel or disassemble the product, otherwise, failure might occur.
Follow the regulations of industrial wastes when the device is to be discarded.

4) Notes on rewriting programs
When rewriting the program in the main unit from the loader while the PLC is running, the built-in RAM is changed, however,
the built-in ash memory is unchanged. As a result, the contents of the RAM does not match those of the ash memory, and
the RUN/MEM LED blinks to prompt the user to transfer the contents of the RAM to the ash memory.
After rewriting the program, be sure to transfer the contents of the RAM to the ash memory. When the transfer is completed
normally, the RUN/MEM LED turns OFF.
<Method 1>
By using the loader, transfer the contents of the RAM to the ash memory.
<Method 2>
After rewriting the program, turn OFF the main unit and then ON again. When the power supply is turned ON, the contents
of the RAM is automatically transferred to the ash memory.

Notes:
1) You can increase or decrease the size of the standard memory (excluding high-speed memory), retain memory, user FB
instance memory, and system FB instance memory by the loader. The default values are shown in the gure above. For
details, see “3-3-2 CPU memory size denition.”
2) The rst 4K words of the standard memory (M) are used as a high-speed memory for high-speed access. You cannot
change the size.
3) For the input/output address assignment, see “1-4 I/O Address Assignment.”
4) You can set the initial values of the standard memory and retain memory using the free space of the program memory.
Initial values require 2.5 steps per variable.
5) The initial value setting memory is automatically allocated according to the size of the user FB instance memory and uses

Key points:
G
1) In the direct addressing mode, this memory area is specied in he format of %Mo1. ... (replace o with any of X, W, or D).
Usually, since a variable declaration is used to assign memory to an application program, you may neglect addresses in
programming. See “1-5 variables” for details.
2) The specied memory area is reset to (0) zero when self-PLC is started.
3) 4K words from the top of the standard memory is the area where data access in the CPU is processed at high speed.
4) The sizes of the standard memory areas can be changed taking those of other areas into account. Note that the size of
the high-speed access memory area is xed to 4K words and cannot be changed.
For the details of memory size change, see “3-3-2 CPU memory size denition.”
5) No continuous access is allowed to the high-speed access memory area and the boundaries between other areas.
