When an Ethernet device with a different network address is accessed
The following system configuration is used to explain an example of communications.

Ethernet device
(request source device)
Ethernet adapter
module 1 (station No.1)
192.168.3.1
Network No.3
No. Module transferring the IP packet

Ethernet adapter module 1 (station No.1)

Master station 1 (station No.0)

Local station 1 (station No.2)
Master station 2 (station No.0)

Ethernet adapter module 2 (station No.1)
*1 When the network address of the Ethernet 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 Ethernet device side is used as a network No. In the routing parameters of the CPU module, set
the communication path to the network No.3.
*2 Because the network address of the Ethernet device (request destination device) is different from that of the master station, the Ethernet
part does not have a network No. In the routing parameters, set the communication path to the network No.2.
■Setting in the Ethernet adapter module 1 (station No.1)
Use the configuration tool to set the IP address.
1.
Set the IP address in the Ethernet adapter module 1 (Ethernet part) as follows.

2.
The IP address setting is not required for the Ethernet adapter module 1 (CC-Link IE Field Network part).
The network address set in the master station 1 (station No.0) is automatically assigned.
