4.3 IP Packet Transfer Function 4.3.5 Precautions
(6) Precautions when configuring a multiple CPU system
Set a CPU module connected to an Ethernet device as a control CPU of the CC-Link IE Controller Network
module performing the IP packet transfer.
Any relay station on CC-Link IE Controller Network can be served as a control CPU of the CC-Link IE Controller
Network module transferring the IP packet.
When multiple CC-Link IE Controller Network modules with the same network number are connected to one
system, the CC-Link IE Controller Network module with the smallest slot number transfers the IP packet.
To transfer the IP packet, connect the Ethernet device to a control CPU of the CC-Link IE Controller Network
module with the same network number and the smallest slot number.
