IP Communications over CC-Link IE Field Network (IP
Packet Transfer Function)
This section describes an example of communications using the specified IP address between external devices over
CC-Link IE Field Network.
*1 Check the corresponding serial No. and software version. ( Page 240, Appendix 10)
● The data that are communicated using the IP packet transfer function are communicated separately by the following
process.
• Service process by a sequence scan of a CPU module (when communications are transferred through the CPU
module)
• Link scan on CC-Link IE Field 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 communication using the IP packet transfer function is
described in the manual for the master/local module used. ( User's manual for the master/local module used)
● To perform IP communications over CC-Link IE Field Network, the CPU module and the master/local module on the
communication route must support the IP packet transfer function. To check whether the CPU module and the
master/local module used support the IP packet transfer function, refer to the sections listing the functions and added
functions in the user's manual for those modules.
● IP communications over CC-Link IE Field Network enable communications with an external device connected to the built-
in Ethernet port of a CPU module. For the applicable system configuration, IP address setting rule, and accessible range,
refer to the following.

● Using the UDP protocol may reduce the data reliability compared to TCP, causing a problem such as data missing and
changed order of data receiving. If any problem occurs, change the protocol to TCP.
● IP communications over CC-Link IE Field Network cannot transfer communications of Broadcast and Multicast. Use
Unicast (identifying a single request destination) instead.
