A new version of the CC-Link Open fieldbus has been developed specifically for applications where the I/O is distributed as a low density widespread network.
Named CC-Link/LT, typical application would include sensor networks around a processing plant, environmental data collection, and machine sensing and actuating control systems.
CC-Link (Control & Communication Link) is an industrial field level network that processes both control and information data at high speed, to provide efficient, integrated factory and process automation. It provides high speed, deterministic communication linking a wide range of multivendor automation devices over a single cable.
With its high performance capabilities, CC-Link is ideally suited for many machine, cell or process control applications. CC-Link/LT complements this by addressing those applications that do not need CC-Link’s full capabilities but which would benefit from many of the advantages.
Offering a bit-oriented control network for widespread I/O applications involving numerous locations of smaller increments of I/O points, CC-Link/LT simplifies wiring both for field devices and within control panels. This ensures that wiring errors are minimised and installation time is reduced
CC-Link/LT utilises the same open technology as CC-Link, and can seamlessly integrate and communicate with CC-Link through a network bridge, as well as operating in a standalone mode. A specially-designed flat network cable carries both communication and power wiring. The CC-Link/LT “one-touch” connector enables a fast, reliable connection to the communication cable for easy changes or to expansion of your network application.
Employing the same technology used in CC-Link, CC-Link/LT provides excellent noise immunity that results in an extremely reliable communication system. CC-Link/LT Remote I/O units are available in a wide range of configurations to accommodate various equipment and assembly line applications.
For OEMs, the process to design CC-Link or CC-Link/LT compatible devices simply involves integrating an ASIC into the product. The CC-Link Partners Association (CLPA) can provide technical assistance and hardware development kits. A CLPA conformance testing laboratory will certify product’s compatibility with CC-Link/LT networking.
