7.3.7 Setting to access a different network address
When the IP address does not meet the rules described on Page 106, Section 7.3.1 (1), the following settings are
required in addition to the setting described on Page 109, Section 7.3.4 so that communications reach an external
device with a different network address.
• A communication route to the Ethernet adapter module connected to the external device with a different
network address (routing parameters)
• A network number and station number of the Ethernet adapter module connected to the external device with
a different network address (CC-Link IE Field Network gateway setting)
(1) Routing parameters
• A communication route to an external device with a different network address
Set the communication route to the Ethernet adapter module (CC-Link IE Field Network part) connected to
an external device.
• A communication route to an external device with the same network address as that of the master station
Set the communication route to the Ethernet adapter module (Ethernet adapter part).
Ex.
*1 When the network address of the external device and Ethernet adapter module (Ethernet part) is the same as that of the
master station, the third octet of the IP address of the external device side is used as a network number. In the routing
parameters of the CPU module, set the communication route to the network number 3.
*2 Because the network address of the external device is different from that of the master station, the Ethernet part does
not have a network number. In the routing parameters, set the communication route to the network number 2.
