Chapter 9 Remote Password - Mitsubishi MELSEC L Series User Manual

CHAPTER 9
A remote password is checked when a connection is requested for the following.
• Communication using a programming tool
• Communication using MC protocol
• File transfer (FTP)
The remote password function is one of the preventive methods against unauthorized access (e.g. destruction of data and
programs) from external devices.
However, this function cannot completely prevent unauthorized access.
Other preventive measures should be taken at users' discretion if security of the programmable controller system needs to
be maintained against unauthorized access from external devices. We cannot be held responsibility for any problems
caused by unauthorized access.
[Examples of measures against unauthorized access]
• Install a firewall.
• Set up a personal computer as a relay station, and control the relay of communication data using an application
program.
• Set up an external device that can control access rights as a relay station.
For devices that can control access rights, please consult your network service provider or networking equipment
vendors.
