Setting for when the network addresses are different
When the same network address cannot be set for the external device and CC-Link IE Field Network, the following
settings are required. (
• Connection to CC-Link IE Field Network (
• Routing parameters: A communication route to the Ethernet adapter module connected to the external
device with a different network address (
• CC-Link IE Field Network gateway setting: A network number and station number of the Ethernet adapter
module connected to the external device with a different network address (
(1) Routing parameters
(a) 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.
(b) 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).
*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.
