SAFETY PRECAUTIONS

(Read these precautions before using this product.)

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

to safety to handle the product correctly.

The precautions given in this manual are concerned with this product only. For the safety precautions of the

programmable controller system, refer to the user's manual for the CPU module used.

In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION".

Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to

serious consequences.

Observe the precautions of both levels because they are important for personal and system safety.

Make sure that the end users read this manual and then keep the manual in a safe place for future

reference.

[Design Precautions]

WARNING

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

network.

Failure to do so may result in an accident due to an incorrect output or malfunction.

●To prevent the malfunction of the programmable controller system due to harmful e-mails, take

preventive measures (such as antivirus measures) so that the mail server for this module does not

receive harmful e-mails.

●When connecting a peripheral with the CPU module or connecting a personal computer with an

intelligent function module to modify data of a running programmable controller, configure an interlock

circuit in the sequence program to ensure that the entire system will always operate safely.

For program modification and operating status change, read relevant manuals carefully and ensure

the safety before operation.

Especially, when a remote programmable controller is controlled by an external device, immediate

action cannot be taken if a problem occurs in the programmable controller due to a communication

failure.

To prevent this, configure an interlock circuit in the sequence program, and determine corrective

actions to be taken between the external device and CPU module in case of a communication failure.

WARNING

CAUTION

Indicates that incorrect handling may cause hazardous conditions,

resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions,

resulting in minor or moderate injury or property damage.

[Design Precautions]

[Security Precautions]

[Operating Precautions]

WARNING

●Do not write any data in the "system area" of the buffer memory in the intelligent function module.

Also, do not use any “use prohibited” signals as an output signal from the CPU module to the

intelligent function module.

Doing so may cause malfunction of the programmable controller system.

CAUTION

●Do not install the control lines or communication cables together with the main circuit lines or power

cables.

Keep a distance of 100mm or more between them.

Failure to do so may result in malfunction due to noise.

●When changing the operating status of the CPU module (such as remote RUN/STOP) from the

external device, select "Always wait for OPEN (Communication possible at STOP time)" for the "Initial

timing" setting in the network parameter.

The communication line will be closed when "Do not wait for OPEN (Communications impossible at

STOP time)" is selected and the remote STOP is executed from the external device.

Consequently, the CPU module cannot reopen the communication line, and the external device

cannot execute the remote RUN.

WARNING

●To maintain the security (confidentiality, integrity, and availability) of the programmable controller and

the system against unauthorized access, denial-of-service (DoS) attacks, computer viruses, and other

cyberattacks from external devices via the network, take appropriate measures such as firewalls,

virtual private networks (VPNs), and antivirus solutions.

CAUTION

●When changing data and operating status, and modifying program of the running programmable

controller from a personal computer connected to an intelligent function module, read relevant

manuals carefully and ensure the safety before operation.

Incorrect change or modification may cause system malfunction, damage to the machines, or

accidents.
