1.5 CC-Link

1.5.1 Overview of CC-Link

CC-Link is a Fieldbus network that provides easy interconnection between control devices
(PLC, PC, sensor, actuator, etc.).
CC-Link was developed as an open communication standard to connect various field
devices (sensor, actuator, robot controller, etc.). Because of the open communication
standard, CC-Link can easily construct multi-vendor system with various devices
developed around the world.

1.5.2 Features of CC-Link

Reduced Wiring
Compared with a parallel wiring, CC-Link employs triplex shielded twisted pair cable
which substantially reduces the number of necessary wires, wiring time and cost.
Detachable communication connector provides you a simple wiring between devices
(nodes) and an easy network separation or reconstruction.
Fast Communication
From 156k bps to 10M bps is available. The speed of 10M bps is the fastest field network
next to PROFIBUS-DP.
Transmission Control
The communication network includes master stations and slave stations. Normally, PLC
becomes a master station. Up to 64 slave stations can be connected to a master station.
The slave station includes remote device stations (handling the bit data and word data),
remote I/O stations (handling the bit data), and others. The master station stores the
information such as the type and address of slave stations in the network and controls the
whole network.
Open Standard (Multi-vendor)
Due to an open communication standard, various devices from many manufactures are
available. Standardized communication connectors allow you to reconstruct your network
easily.
