Fieldbus suits low-density networks
CC-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.
A new version of the CC-Link Open fieldbus has been developed for applications where the I/O is distributed as a low-density, widespread network The CC-Link/LT suits sensor networks around a processing plant, environmental data collection, machine sensing and actuating control systems

If the active master PLC processor fails for any reason, the standby PLC processor takes control immediately with a "bumpless" changeover.
Explaining worldwide fieldbus differences
All fieldbus protocols share the same, really rather short, history, but that does not mean they are anything like equal.
CC-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 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 of field devices and within control panels.
This ensures that wiring errors are minimised and installation time is reduced.
CC-Link/LT uses 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 stand-alone mode.
A 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 expansion of the 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.
Designing 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. Request a free brochure from CC-Link Partner Association ...
