Fast and failsafe industrial communiation

The Beckhoff Lightbus system is a fast and failsafe serial fieldbus system that was conceived for high speed automation technology. Low-cost and easy-to-process standard fiber optic conductor technology is used for transmission. The crucial advantages of the fiber optic conductor are interference immunity to electromagnetic influences, complete electrical isolation of connected modules from one another and a high data transfer rate. In conjunction with an optimized, compact telegram structure, Lightbus permits a very high user information data transfer rate of up to 2.5 Mbits/s.

With one Lightbus interface board, up to 255 decentralized modules can be operated with a maximum distance of up to 300 m between two modules.

With efficient test functions and diagnostics, individual Lightbus module functions and communication in the entire Lightbus ring are monitored cyclically and automatically. Changes or additions to a system configuration can be made easily and reliably by means of configuration programs in the Lightbus system.

Lightbus is open and universally applicable. Lightbus interfaces are available for common bus and computer architectures, from the standard PC up to VME computers, and for control systems in use around the world.

The wide range of distributed Lightbus components cover the requirements found in automation technology for items from displacement sensors, through universal Bus Terminals up to drive controllers.
