CAUTION:
The Ethernet IP filtering function (Pr. 1442 to Pr. 1448) is provided as a means to prevent
unauthorized access (with intentions such as to corrupt programs or data) by external systems,
but the function does not prevent it completely. In order to protect the inverter and the system
against unauthorized access by external systems, take additional security measures. Mitsubishi
Electric Corporation will not take any responsibility for any problems in the inverter and the
system incurred by unauthorized access.
The following are examples of measures to prevent unauthorized access.
●
Install a firewall.
●
Install a personal computer as a relay station, and control the relaying of transmission data
using an application program.
●
Install an external device as a relay station to control access rights.
(For the details of external devices used to control access rights, contact the distributors of
the external devices.)
