Specifications
CC-Link
■ Easy connection of bit level devices combined with advanced message and data
transmission is now a reality with CC-Link, a field network system giving more
sophisticated field information control while reducing cabling costs.

■ Control & information
For CC-Link system, three types of remote devices are con-
nected as follows:
Remote I/O: Field devices which only require ON/OFF
control for their function such as digital I/O or pneumatic
valves are specified as this type. Only bit data can be
communicated with this device type.
Remote Device: Field devices which handle register values
(numeric data) such as analog I/O and counters are
specified as this type. In addition to bit data, register data
can also be communicated.
Intelligent Remote: This is a device which is allowed to
access the master and/or other stations actively for data
acquisition and control. Local PLCs,GOTs and programming
interface units are specified as this type.
■ 10M bps high speed data transmission
CC-Link was developed not only for fast remote I/O control,
but also for fast field information control. For this purpose,
the transmission speed of CC-Link has been increased to
10Mbps compared to our previous field network system.
This high speed performance allows communication of
large volumes of data without affecting machine control
speed.
■ Personal computer connection
The A80BDE-J61BT13 computer board (PCI bus) operates
as a local station within CC-Link. This PC board allows both
monitoring and testing of CC-Link from a personal
computer. Users can develop their own monitor or test
software in Visual Basic Ver. 5.0 or Visual C++ Ver. 5.0.
■ Master/local configuration
Unlike other field networks, CC-Link can configure master-
local configuration in addition to master-remote con-
figuration. A local PLC can communicate with the master
PLC and other remote stations.
■ Multi-vendor connection
Many sensor and actuator vendors have joined the CC-Link
partner program for direct connection of their devices with
the network. Examples of devices are pneumatic valve, ID
controller, bar code reader, robotics, display terminal,
temperature controller and measurement sensors.
■ Hot/stand-by master configuration
A local PLC in CC-Link system can act as a stand-by master
PLC for master PLC redundancy. Because of the increasing
importance of filing data, such data should not be lost if the
master shuts down. This function for CC-Link system gives
a simple and inexpensive solution for redundant systems.
■ On-line I/O replacement
2-piece terminal block construction of remote I/O allows
on-line I/O replacement without affecting other remote I/O
control.
