CC-Link system description

This chapter provides a brief general introduction to the CC-Link network.

CC-Link (Control and Communication Link) was developed by Mitsubishi Electronic Corporation in 1996 as a semi-open, proprietary network to allow its products to communicate with each other in a system. In 2000, Mitsubishi Electronic Corporation specified CC-Link as a completely open network and founded the CLPA (CC-Link Partner Association). Since CC-Link is an open network and the protocols are available to all interested parties, anyone can develop their own CC-Link interfaces. The intention is to increase the worldwide acceptance and interest.

CC-Link is a high-speed, deterministic field network that can process control and information data simultaneously at a maximum speed of 10 Mbps over a maximum distance of up to 100 meters. CC-Link is used for control of individual machines or entire factories and in building automation. Up to 64 stations can communicate with each other in a network. A distinction is made between CC-Link versions 1.00 (or 1.10) and version 2.00. The difference between the versions is in the amount of data transferred. CC-Link version 2.00 supports 8 times the amount of communication data in the system and per CC-Link station.
