(2) When accessing an Ethernet device with a different network address
The following system configuration is used to explain an example of communications.
*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 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 Ethernet device (request destination 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.
(a) Setting in the Ethernet adapter module 1 (station number 1)
1. Set the IP address in the Ethernet adapter module 1 (Ethernet part).
Use the configuration tool to set the IP address in the Ethernet adapter module 1 (Ethernet part).
Setting item tree NZ2GF-ETB [Parameter] "Ethernet"
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 number 0) is automatically assigned.
No. Module transferring the IP packet IP address
