Remote Password - Mitsubishi Electric MELSEC iQ-R Series User Manual

Remote password

Permits or prohibits access from the external device to the CPU module via the CC-Link IE TSN Plus module. This function
can prevent illegal access of the CPU module from a remote location.
The remote password is one method of preventing illegal access (such as program or data destruction) from
an external device. It does not completely prevent illegal access. 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, take appropriate
measures such as firewalls, virtual private networks (VPNs), and antivirus solutions.
Our company is not responsible for any problems that occur in the programmable controller and system due to
a DoS attack, unauthorized access, computer virus, or other cyber attacks.
Examples of measures for unauthorized access are given below.
• Install a firewall or VPN.
• Install a personal computer as a relay station, and control the relay of send/receive data with an application
program
• Install an external device for which the access rights can be controlled as a relay station (Contact the
network provider or equipment dealer for details on the external devices for which access rights can be
controlled.)
Number of settable modules
Up to eight modules can be set for remote passwords.
When using the multiple CPU system configuration, up to eight modules can be set for each CPU module.
