4.3.2 How to set the IP packet transfer function
To use the IP packet transfer function, the following items need to be set.
and need to be set only for the CPU module connected to an Ethernet device.
● Ethernet device gateway address setting
Set the IP address of the CPU module connected to an Ethernet device in the gateway address of the Ethernet device
used.
• When the Ethernet device is a personal computer
It is recommended to configure the gateway address setting using the route command. (This only applies to an
Ethernet device having the route command such as Microsoft
®
Windows
®
.)
If the gateway address is set in the default gateway, packets not related to the IP packet transfer are also
transmitted through the CPU module. Consequently, the service process of the CPU module drops under heavy
load, causing other service processes to be slow or other problems.
● Checking after the setting is completed
Execute the IP communication test to check for an error in the communication route. ( Page 113, Section 4.3.3)

IP packet transfer setting ( Page 111, Section 4.3.2 (2) (a))
This setting is required for the IP packet to be passed between a CPU module and a CC-Link IE Controller
Network module.
