1.1
CC-Link IE Field Network
CC-Link IE Field Network is a high-speed and large-capacity open field network that is based on Ethernet technology
(1000BASE-T).

(1) Data communication

High-speed and large-capacity data communication is available between a master station and slave stations on
CC-Link IE Field Network.
(a) Periodic communication (cyclic transmission)
Data is periodically communicated among stations within the same network. (
CPU module
(b) Irregular communications (transient transmission)
