7.7 Remote Password
This function checks a remote password when the communication using the following
connections is requested.
• Communication using GX Developer
• Communication using the MC protocol
• File transfer
POINT
The remote password function is a function to prevent unauthorized access (ex.
corrupting data and programs) from external devices. However, this function
cannot completely prevent unauthorized access.
Users should incorporate safety measures by themselves 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 control access authority as a relay station.
• Please consult a network provider or equipment sales company regarding
external devices that can control access authority.
