Versatile Automation Random Access Network

When selecting the right bus system for machine automation, reliability plays a central role in addition to the speed.

Based on globally proven Ethernet physics, the hard real-time at the lowest cycle times and maximum data security is provided.

Robust, error-tolerant maintenance in raw industrial environments is also an important performance characteristic of a modern bus system. As a real-time Ethernet bus system, the VARAN bus meets these requirements and offers much more.

Instead of standard Ethernet frames, smaller data packets are used with the VARAN bus, guaranteeing the highest possible resistance to disruptions. The immediate repetition of unacknowledged messages within a bus cycle is one of the most important advantages, which characterize the VARAN bus as a future-oriented bus system.
