CC-Link IE - Gigabit Industrial Ethernet

A new integrated Ethernet network

Open-technology, CC-Link IE Field brings vast new possibilities to the world of automation.

To meet the changing demands for optimised control, openness, reliable, and deterministic handling of data on industrial communication networks, the CC-Link Partner Association (CLPA) announces this 1-Gigabit Ethernetbased integrated network. CC-Link IE enables seamless data communication from the plant-level enterprise network to the production floor network. This integrated industrial network philosophy also provides cost reduction for the total system engineering task from system start-up, operation, and maintenance

High speed, deterministic Ethernet networking.

Because CC-Link IE Field is an open-technology network, the global CLPA organisation supports and assists partner companies in the development of their CC-Link IE Field compatible products. This allows the end-user to choose from a variety of value-added products for their automation systems.

Features of CC-Link IE Field

Ultra-high speed
One gigabit-per-second transmission and real-time protocol enables control of remote I/O field devices with essentially no transmission delay. This transmission rate is at least ten times faster than currently available Industrial Ethernet-based networks. CC-Link IE Field network is the first gigabit industrial Ethernet network extended down to the field device level. It combines the best of existing technologies and applies them in a highly reliable architecture that provides exceptional data bandwidth and transaction rates. The new network uses commercially available Cat5E cable and RJ45 connectors.

Inherent determinism without Ethernet switches
The significant difference between CC-Link IE Field Network and other Industrial Ethernet solutions is that CC-Link IE Field Network delivers deterministic control communications without requiring the addition of Ethernet switches. This feature eliminates the hardware costsand engineering implementation costs of those switches. Also, the cost and need for developing communication statements to govern the flow of data is eliminated due to the shared memory concept of CC-Link IE Field and no knowledge of CC-Link IE Field protocol is required. Determinism is guaranteed by the CC-Link IE Field token-passing technique.

Flexible topology
A CC-Link IE Field Network allows for a topology best suited to the needs of the particular application — thus ensuring greatest flexibility. These topologies include star, line, mixed star and line, and ring. Within a single network there can be a total of 120 stations with up to 328 feet (100 meters) of Cat5E cable between each station. In addition, as many as 239 networks can be interconnected allowing vast exchange of data to suit any application.
