[Design Precautions]
 Do not write any data into the "System area" of the buffer memory of the intelligent function
module.
Also, do not output (turn on) the "Use prohibited" signal, which is one of the output signals from
the programmable controller CPU to the intelligent function module.
If data is written to the "System area" or the "Use prohibited" signal is output, there is a risk that
the programmable controller system may malfunction.
[Design Precautions]
 Do not bunch the control wires or communication cables with the main circuit or power wires, or
install them close to each other.
They should be installed 100 mm (3.94 inch) or more from each other.
Not doing so could result in noise that would cause erroneous operation.
 Do not power off a station where this module is mounted and do not reset the programmable
controller CPU while storing the settings into the standard ROM of the module using a Web
browser.
This may make the data unstable within the standard ROM and require resetting and re-storing,
or it may cause a failure or malfunctions of the module.
[Security Precautions]
 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.
