Remote Password - Mitsubishi Electric MELSEC iQ-F FX5 Series User Manual

Remote password

This function permits or prohibits access from the external device to the CPU module via the Motion module. This prevents
unauthorized access to the CPU module from a remote location.
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. Take appropriate measures
other than this function if the safety of the programmable controller system must be maintained against
unauthorized access from an external device. Mitsubishi shall not be held liable for any system problems that
may occur from unauthorized access.
Examples of measures for unauthorized access are as follows.
• Install a firewall.
Number of settable modules
Only one password for "Register Password" can be registered.
Maximum settable remote passwords are three (master station, local station, and a CPU module).
