IP Packet Transfer Function

Communications using the specified IP address can be performed over CC-Link IE Field Network.
For example, a personal computer can communicate with the FTP server.
With this function, two networks of CC-Link IE Field Network and Ethernet are not required, resulting in reduced wiring
cost.
Conventional way
When the IP packet transfer function is used
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
• 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 communications using the IP packet transfer function is
described in Page 172, Section 8.3.8

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