Software libraries for Windows operating systems are available for the Lightbus. All the necessary functions for communication over the Lightbus are implemented. The communication interface is linked into the operating system as a device. A large number of functions are conveniently utilised within customer’s own software written in high-level languages.

Using active communication interfaces with a dedicated communication processor, the Lightbus system’s process image is cyclically made available in dual-ported RAM. This leaves the system processor entirely free for application tasks.

The fast interrupt capability of the Lightbus system is supported by the active communication cards, permitting signals to be sampled every 25 µs over large distances. The Lightbus system and its software libraries provide an ideal input/output medium for many computer systems.
