4.3 IP Packet Transfer Function
Communication using the specified IP address can be performed over CC-Link IE Controller Network.
For example, a personal computer can communicate with the FTP server.
With the IP packet transfer function, two networks of CC-Link IE Controller Network and Ethernet are not required,
resulting in reducing the wiring cost.
To use the IP packet transfer function, the setting with GX Works2 is required. GX Developer cannot be used for
setting.
The data that are communicated using the IP packet transfer function are communicated separately by the following
processes.
• Service processing by a sequence scan of a CPU module
• Link scan on CC-Link IE Controller Network
Because of this, the speed of communications using the IP packet transfer function is slower than the speed of
communications with the Ethernet line. The reference speed of communications using the IP packet transfer function is
described in Page 122, Section 4.3.7.

Two networks were required.
Only CC-Link IE Controller Network is
required to perform communications
using an IP address.
