Test Run
Before you start a Test Run, make sure that the operation parameters are set correctly.
Actual Operation
Check the user program, servo algorithm, data, and parameter settings for proper exe-
cution before you use them for actual operation.
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 sys-
tems and equipment.
• Reduce connections to control systems and equipment via networks to prevent ac-
cess from untrusted devices.
• Install firewalls to shut down unused communications ports and limit communica-
tions hosts and isolate control systems and equipment from the IT network.
• Use a virtual private network (VPN) for remote access to control systems and equip-
ment.
• Adopt multifactor authentication to devices with remote access to control systems
and equipment.
• Set strong passwords and change them frequently.
• Scan virus to ensure safety of USB drives or other external storages before connect-
ing them to control systems and equipment.
Data input and output protection
Validate backups and ranges to cope with unintentional modification of input/output da-
ta to control systems and equipment.
• Checking the scope of data
• Checking validity of backups and preparing data for restore in case of falsification
and abnormalities
• Safety design, such as emergency shutdown and fail-soft operation in case of data
tampering and abnormalities
Data recovery
Backup data and keep the data up-to-date periodically to prepare for data loss.
When using an intranet environment through a global address, connecting to a SCADA
or an unauthorized terminal such as an 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.
