SAFETY PRECAUTIONS

(Read these precautions before use.)

Before using this product, please read this manual and the relevant manuals introduced in this manual carefully and pay full

attention to safety to handle the product correctly.

This manual classifies the safety precautions into two categories: [ WARNING] and [ CAUTION].

Depending on the circumstances, procedures indicated by [ CAUTION] may also cause severe injury.

It is important to follow all precautions for personal safety.

Store this manual in a safe place so that it can be read whenever necessary. Always forward it to the end user.

[DESIGN PRECAUTIONS]

WARNING

●Make sure to set up the following safety circuits outside the programmable controller to ensure safe

system operation even during external power supply problems or programmable controller failure.

Otherwise, malfunctions may cause serious accidents.

- Most importantly, set up the following: an emergency stop circuit, a protection circuit, an interlock

circuit for opposite movements (such as normal vs. reverse rotation), and an interlock circuit to

prevent damage (to the equipment at the upper and lower positioning limits).

- Note that when the CPU module detects an error, such as a watchdog timer error, during

selfdiagnosis, all outputs are turned off. Also, when an error that cannot be detected by the CPU

module occurs in an input/output control block, output control may be disabled. External circuits

and mechanisms should be designed to ensure safe machinery operation in such a case.

- Note that when an error occurs in a relay, transistor or triac of an output circuit, the output might

stay on or off. For output signals that may lead to serious accidents, external circuits and

mechanisms should be designed to ensure safe machinery operation in such a case.

●In an output circuit, when a load current exceeding the rated current or an overcurrent caused by a

load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an

external safety circuit, such as a fuse.

●For the operating status of each station after a communication failure of the network, refer to relevant

manuals for the network. Incorrect output or malfunction may result in an accident.

●Construct an interlock circuit in the program so that the whole system always operates on the safe

side before executing the control (for data change) of the programmable controller in operation.

Read the manual thoroughly and ensure complete safety before executing other controls (for program

change, parameter change, forcible output and operation status change) of the programmable

controller in operation.

Otherwise, the machine may be damaged and accidents may occur due to erroneous operations.

●Especially, in the case of a control from an external device to a remote programmable controller,

immediate action cannot be taken for a problem on the programmable controller due to a

communication failure. Determine the handling method as a system when communication failure

occurs along with configuration of interlock circuit on a program, by considering the external

equipment and CPU module.

WARNING Indicates that incorrect handling may cause hazardous conditions, resulting in

death or severe injury.

CAUTION Indicates that incorrect handling may cause hazardous conditions, resulting in

minor or moderate injury or property damage.

[DESIGN PRECAUTIONS]

[INSTALLATION PRECAUTIONS]

●Do not write any data to the "system area" and "write-protect area" of the buffer memory in the

module. Executing data writing to the "system area" or "write protect area" may cause malfunction of

the programmable controller alarm. For the "system area" and "write-protect area", refer to Page

126 Buffer Memory.

●If a communication cable is disconnected, the network may be unstable, resulting in a communication

failure of multiple stations. Construct an interlock circuit in the program so that the system always

operates on the safe side even if communications fail. Incorrect output or malfunction may result in an

accident.

●To maintain the safety of the programmable controller system against unauthorized access from

external devices via the network, take appropriate measures. To maintain the safety against

unauthorized access via the Internet, take measures such as installing a firewall.

CAUTION

●Do not bundle the control lines or communication cables together with or lay them close to the main

circuit or power line. As a guideline, lay the control line and communication cables at least 100 mm

away from the main circuit or power line. Failure to do so may result in malfunction due to noise.

●When an inductive load such as a lamp, heater, or solenoid valve is controlled, a large current

(approximately ten times greater than normal) may flow when the output is turned from off to on. Take

proper measures so that the flowing current does not exceed the value corresponding to the

maximum load specification of the resistance load.

●After the CPU module is powered on or is reset, the time taken to enter the RUN status varies

depending on the system configuration, parameter settings, and/or program size.

Design circuits so that the entire system will always operate safely, regardless of the time.

●Simultaneously turn on and off the power supplies of the CPU module and extension modules.

●If a long-time power failure or an abnormal voltage drop occurs, the programmable controller stops,

and output is turned off. When the power supply is restored, it will automatically restart. (when the

RUN/STOP/RESET switch is on RUN side).

WARNING

●Make sure to cut off all phases of the power supply externally before attempting installation or wiring

work. Failure to do so may cause electric shock or damage to the product.

●Use the product within the generic environment specifications described in the User's Manual

(Hardware) for the CPU module used.

Never use the product in areas with excessive dust, oily smoke, conductive dusts, corrosive gas (salt

air, Cl2, H2S, SO2or NO2), flammable gas, vibration or impacts, or expose it to high temperature,

condensation, or rain and wind.

If the product is used in such conditions, electric shock, fire, malfunctions, deterioration or damage

may occur.

WARNING

[INSTALLATION PRECAUTIONS]

accidents due to malfunction of the programmable controller caused by abnormal data written to the

programmable controller due to the effects of noise.

- Do not bundle the power line, control line, and communication cables together with or lay them

close to the main circuit, high-voltage line, load line, or power line. As a guideline, lay the power

line, control line and connection cables at least 100 mm away from the main circuit, high-voltage

line, load line or power line.

- Ground the shield of the shield wire or shielded cable at one point on the programmable controller.

However, do not use common grounding with heavy electrical systems.

●Use a cable dedicated for the PROFIBUS system. Otherwise, the performance of the PROFIBUS

system cannot be guaranteed. Also, for the total extension length of the cables and cable length

between stations, make sure to follow the specifications described in this manual. If wiring not in

accordance with the specifications is performed, normal data transmission cannot be guaranteed.

●Check the interface type and correctly connect the cable. Incorrect wiring (connecting the cable to an

incorrect interface) may cause failure of the module and external device.

WARNING

●Do not touch any terminal while the programmable controller's power is on. Doing so may cause

electric shock or malfunctions.
