3.1 Overview
The open fieldbus and control network CC-Link (Control & Communication Link) provides fast data
communications with different devices. As with all manufacturer specific networks, CC-Link is quickly
implemented and is guaranteed to work. CC-Link is also an open network and therefore allows many
third-party products now appearing on the market with CC-Link connectivity.
Structure
A CC-Link system consists of a master and up to 64 slave stations.
● Master: The master has the control information (parameters) and controls the entire network.
One Master station is required in each network. The station number is fixed to 0.
● Slave: The CC-Link slaves are the link to the field side. They edit the input data of the peripheral
equipment for the communication with the master and output the master data to the peripheral
equipment.
● Station: A station is a device that is connected via the CC-Link. Station numbers from 1 to 64 can
be assigned.
● Remote device station: A station that can use bit data and word data (Example: Digital and
analog I/O modules).
● Remote I/O station: A station that can only use bit data (Example: Digital I/O modules)
Transmission speeds from 156 kbit/s to 10 Mbit/s can be used. The maximum transmission distance
is limited from 100 to 1200 m, depending on the bit rate used.
Cable types
The data communications requires standardized shielded twisted-pair cable with 3 wires.
