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).
Data communication
High-speed and large-capacity data communication is available between a master station and slave stations on the CC-Link
IE Field Network.
■Periodic communication (cyclic transmission)
Data is periodically communicated among stations within the same network. (Page 60 Cyclic Transmission)
