Precautions for Correct Use
Security Measures
 Anti-Virus Protection
Install the latest commercial-quality antivirus software on the computer connected to the control system
and maintain to keep the software up to date.
 Security Measures to Prevent Unauthorized Access
Take the following measures to prevent unauthorized access to our products:
• Install physical controls so that only authorized personnel can access control systems and
equipment.
• Reduce connections to control systems and equipment via networks to prevent access from
untrusted devices.
• Install firewalls to shut down unused communications ports and limit communications hosts and
isolate control systems and equipment from the IT network.
• Use a virtual private network (VPN) for remote access to control systems and equipment.
• Adopt multifactor authentication to devices with remote access to control systems and equipment.
• Set strong passwords and change them frequently.
• Scan for viruses to ensure safety of USB drives or other external storage devices before connecting
them to control systems and equipment.
 Data Input and Output Protection
Validate backups and ranges to cope with unintentional modification of input/output data to control
systems and equipment.
• Check the scope of data.
• Check validity of backups and prepare data for restore in case of falsification or abnormalities.
• Safety design, such as emergency shutdown and fail-soft operation in case of data tampering or
abnormalities.
 Data Recovery
Back up and update data periodically to prepare for data loss.
When using an intranet environment through a global address, connecting to an unauthorized terminal
such as a SCADA, HMI or to an unauthorized server may result in network security issues such as
spoofing and tampering.
You must take sufficient measures such as restricting access to the terminal, using a terminal equipped
with a secure function, and locking the installation area by yourself.
When constructing an intranet, communication failure may occur due to cable disconnection or the
influence of unauthorized network equipment. Take adequate measures, such as restricting physical
access to network devices, by such means as locking the installation area.
When using a device equipped with the SD Memory Card function, there is a security risk that a third
party may acquire, alter, or replace the files and data in the removable media by removing or unmounting
the removable media. Please take sufficient measures, such as restricting physical access to the
controller or taking appropriate management measures for removable media, by means of locking the
installation area, entrance management, etc.
 Software
To prevent computer viruses, install antivirus software on the computer where you use this software.
Make sure to keep the antivirus software updated.
Keep your computer's OS updated to avoid security risks caused by a vulnerability in the OS.
Always use the latest version of this software to add new features, increase operability, and enhance security.
Manage usernames and passwords for this software carefully to protect them from unauthorized uses.
Set up a firewall (e.g., disabling unused communication ports, limiting communication hosts, etc.) on a
network for a control system and devices to separate them from other IT networks.
Make sure to connect to the control system inside the firewall.
Use a virtual private network (VPN) for remote access to a control system and devices from this software.
