CC-Link IE Controller Network is the first open technology, gigabit industrial Ethernet network
for automation. It combines the best of existing technologies and applies them in a highly reliable, redundant architecture that provides exceptional data bandwidth and transaction rates. CC-Link IE provides a consistent, integrated controller network that corresponds to the IEEE 802.3 standard and operates at a communication rate of 1Gbps. CC-Link IE provides seamless control data transmission between devices such as PLCs, computers, HMIs, robots, motion controllers and other assets. It serves an important role in enabling comprehensive data connectivity across the shop floor and enterprise levels.
The CC-Link IE controller network uses token passing for data transmission control. The token passing method results in increased communication throughput, and provides deterministic data exchange and constant link scan time by eliminating the possibility of data collisions. There is no need for any external Ethernet switches or hubs. Up to 120 controller stations can be connected on a single network while providing deterministic data exchange at gigabit speed. In addition, hundreds of CC-Link IE networks can be interconnected for coordinated facility-wide control and data integration.
