■Checking the status of communications
After the setting is completed in each module, execute the IP communication test to check for an error in the communication
path on CC-Link IE Field Network. ( Page 48 IP communication test)
When an Ethernet device with a different network address is accessed
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 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 number. In the routing parameters, set the communication path to the network No.2.
No. Module transferring the IP packet IP address
