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

Remote password

This function permits or prohibits access from the external device to the CPU module via the RJ71GN11-T2. This prevents
unauthorized access to the CPU module from a remote location.
A C Controller module and a MELSECWinCPU module cannot use this function.
The remote password is one method of preventing unauthorized access (such as program or data destruction)
from an external device. It does not completely prevent unauthorized 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 service 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.
