Network technology

CC-Link is the highspeed field network able to simultaneously handle both control and information data. With the high communication speed of 10 Mbps, CC-Link can achieve the maximum transmission distance of 100 meters and connect to 64 stations.

In addition to highspeed 10 Mbps operation, CC-Link is extremely deterministic. Being able to rely on a predictable, unvarying I/O response allows system designers to provide reliable, real-time control.

CC-Link significantly reduces the amount of control and power wiring needed in today's complex production lines. It reduces wiring and installation costs, minimizes the work needed to accomplish the wiring and drastically improves maintenance operations.

CLPA provides a "memory mapped profile" that defines data for each product type. This definition includes the control signal and data layout (addressing). Multiple vendors can develop CC-Link compatible products to match this "profile". Users are then able to easily change from one product brand to another without needing to change connections or control programs.

The maximum overall cable length is 100 meters when 10 Mbps is selected. This length can be extended to 1.2 km when the network speed is 156 Kbps. The use of cable repeaters and optical repeaters allows even greater distances to be covered. CC-Link supports large-scale applications and reduces the work needed for wiring and device installation.

The RAS (Reliability, Availability, and Serviceability) function is another of CC-Link features. Functions including stand-by master, detaching device station, automatic return and testing and monitoring provide high reliability net-work system and allow the system down time to minimize.

Using CC-Link, a stand-by master station can assume control of network communications in the event that the primary master station becomes inoperable.

In the event that a device station stops communicating, CC-Link allows communication to continue with all other stations.

CC-Link automatically returns a disconnected station to full network operation when the fault is corrected.

This function monitors data link status, and conducts a series of hardware and circuit tests.
