[DESIGN PRECAUTIONS]
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 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.
● Do not power off the CPU module or reset the CPU module while the settings are being written. Doing
so will make the data in the flash ROM undefined. The values need to be set in the buffer memory and
written to the flash ROM again. Doing so also may cause malfunction or failure of the module.
[SECURITY PRECAUTIONS]
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 unreliable networks and devices via network, take appropriate measures such as
firewalls, virtual private networks (VPNs), and antivirus solutions.
