 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
setting range for IP address of connectable network devices 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 "9999 (initial value)" is set in Pr.1446 to Pr.1448, 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.)

2.11.4 Object map definitions

 Object model of EtherNet/IP communication
For EtherNet/IP communication, each node is modeled as collections of objects (abstraction of particular functions of the
products). The following four terms are used to describe object.
Item
Class Collections of all objects which have same types of functions. Generalization of object.
Instance Concrete expression of object.
Attribute Expression of object characteristic.
Service Function supported by object or class.
