A CC-Link cable is a cable compatible with CC-Link (Control & Communication Link), an FA network.
CC-Link is an FA network developed by Mitsubishi Electric Corporation that enables high-speed transmission up to 10 Mbps and long-distance communication up to 1,200 m (transmission rate: 156 kbps). CC-Link network can be constructed by connecting a CC-Link compatible PLC and each input/output device with a CC-Link cable.
Generally, shielded 3-core twisted pair cables are used, and each cable supports a different version of CC-Link (backward compatible). Model numbers are assigned according to the intended use, such as for fixed and movable sections, and to the outer jacket color.
CC-Link cables are mainly used in industrial applications.
While hard-wired communication requires the laying of dozens of multi-core cables between devices, CC-Link requires only a 3-core shielded cable to be connected in series via a master station, resulting in low cost and space saving. Therefore, CC-Link is used in production lines where many devices are used. Transmission distance can be extended by using repeaters or optical repeater units.
CC-Link compatible products can be developed by applying to Mitsubishi Electric Corporation, the developer of the CC-Link, as a partner, so cables, measuring instruments, controllers, and other products compatible with the CC-Link are sold by various manufacturers. Furthermore, since memory-mapped profiles are set for each product type, similar programs can be used for other manufacturers' products as long as they have the same functionality for the same application.
CC-Link cables are often shielded 3-core twisted pair cables.
Soft materials such as vinyl are often used for the sheath. In addition, black polyethylene is used for CC-Link cables for outdoor use to improve weather resistance. Since CC-Link cables are used for communication and do not transmit large amounts of electric power, thin conductors of about 0.5 mm2 are used.
Processing and wiring of CC-Link cables are performed in the following steps.
Strip the sheath
Strip the cable sheath. Be careful not to damage the shield mesh.
Processing of the shield
Carefully unwind the shield netting. Insulate one bare drain wire other than the signal line.
Removing the signal line sheath
The removed parts should be firmly aligned.
Attach crimp terminals
Connect the crimp terminals using crimping pliers.
Connection to terminal block
Attach termination resistors to both ends of the network. The resistor used in this case is 110Ω.
Grounding the shield wire
Ground both ends of the shielded wire to the SLD of each unit.
CC-Link IE Field (Control & Communication Link-Industrial Ethernet Field) is an open network developed by the CC-Link Association in 2007. CC-Link is a master-slave serial communication system, while CC-Link IE Field is a communication system based on Gigabit Ethernet.
Since CC-Link IE Field utilizes Ethernet technology, the network is constructed using LAN cables. However, STP cables are used for the cables, which are shielded inside the cables and are resistant to noise.
