Safety Precautions
Be sure to read the "Safety Precautions" thoroughly before using the module.
Here, the safety precautions items are classified into "Warning" and "Caution".
Warning
Caution
: Incorrect handling of the device may result in death or serious injury.
: Incorrect handling of the device may result in minor injury or physical damage.
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
Never 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 PLC might break or
cause problems to the machine.

Safety Precautions
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 operating instructions 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 operating instructions and manual. Use beyond the rated values
might cause fire, erratic operation or failure.
Operate (keep) in the environment specified in the operating instructions and 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.
Periodically make sure the terminal screws and mounting screws are securely tightened.
Operation at a loosened status might cause fire or erratic operation.
Sufficiently make sure of safety before program change, forced output, starting, stopping or anything else during the
system running. 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 operating instructions and
manual. Wrong or loose wiring might cause fire, accident or failure.
When disengaging the plug from the outlet, do not pull the cord, otherwise, break of cable might cause fire or failure.
Do not press on the key switches with an object having a sharp edge, such as tweezers and tool. Do not press them too
strongly Otherwise, they might be flawed or damaged.
Do not attempt to repair the module by yourself, but contact your Fuji Electric agent. When replacing the batteries,
correctly and securely connect the battery connectors, otherwise, fire, accident or failure might occur.
Do not remodel or disassemble the product, otherwise, failure might occur.
Follow the regulations of industrial wastes when the device is to be discarded.
If you intend to use the modules covered in these operating instructions for special applications, such as for nuclear
energy control, aerospace, medical or transportation, please consult your Fuji Electric agent.
Be sure to provide protective measures when using the module covered in these operating instructions in equipment
which, in the event of failure, can lead to loss of human life or other grade results.

(2) Assigning the intterupt activation flag to an event task
To activate an event task by an external interrupt signal, it is necessary to assign the external interrupt activation flag
(%MX10.266.3) to an event variable.
Interrupt input is held temporarily by an internal latch circuit. The default of the latch circuit status is “0” (reset).
To enable interrupt, set the external interrupt enable flag (%MX10.268.3) to ON. The interrupt is disabled (the flag is set OFF)
by default.
If the interrupt is enabled when an interrupt input is already held, the interrupt is activated immediately.
To reset a latch circuit, set the system memory (%MX10.268.15) to ON. When the flag is set to ON, all the latch circuits will
be reset. The latch circuits for comparison match interrupts of high-speed counter are reset at the same time.
When an interrupt program is started, the interrupt latch circuits are reset automatically.
