Ethernet Ip Filtering Function - Mitsubishi Electric A800-E Instruction Manual

Ethernet IP filtering function (Pr.1442 to Pr.1448)
• Set the IP address range for connectable network devices (Pr.1442 to Pr.1448) to limit the connectable devices. The IP
address setting range depends on the settings in Pr.1443 and Pr.1446, Pr.1444 and Pr.1447, and Pr.1445 and Pr.1448.
(Either of the settings can be larger than the other in Pr.1443 and Pr.1446, Pr.1444 and Pr.1447, and Pr.1445 and
Pr.1448.)
[Setting example 1]
Ethernet IP address for filtering
Filtering range setting
for the Ethernet IP address
In this case, the IP address range in which Ethernet communication is permitted is "192.168.x (1 to 3).xxx (100 to 150)".
[Setting example 2]
Ethernet IP address for filtering
Filtering range setting
for the Ethernet IP address
In this case, the IP address range in which Ethernet communication is permitted is "192.168.2.xxx (50 to 100)".
• When Pr.1442 to Pr.1445 = "0 (initial value)", the function is invalid.
• When Pr.1446 to Pr.1448 = "9999 (initial value)", the range is invalid.
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.)
