3.1. What Is CC-Link?
Table 3.1-1 CC-Link Network Configuration Diagram
CC-Link is a field network (*1) that provides not only simple bit control but also additional functions such as
data control and message transmission/reception in order to accommodate the continuous advances in the
functionality of various control devices. CC-Link supports cyclic transmission of not only bit data but also word
data, facilitating communication with intelligent devices such as inverters, indicators and other I/O devices.
Distributed systems can be built easily by setting up an n:n cyclic transmission network to which a master
station and several local stations are connected. The best communication distance and speed can be selected
in a flexible manner according to your system requirements. The optimal system can be built by selecting the
most suited devices from the rich product lines of the CC-Link partner manufacturers.
This CC-Link interface card operates as an intelligent device station.
