New CC-Link suits low-density networks
Another 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, machine sensing and actuating control systems.
CC-Link (Control and 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 multi-vendor automation devices over a single cable.
With its high performance capabilities, CC-Link is suitable 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 network applications.
Employing the same technology as 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 a product's compatibility with CC-Link/LT networking.
