Versatile Automation Random Access Network

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

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

 

Guaranteed hard real-time data transfer
Each instruction is immediately acknowledged by the receiver within the bus cycle
Automatic addressing
No network administration costs
Hot Plug in
Participants can be added or removed during operation
High reliability
In the event of an error, instructions are repeated immediately
Open Standard
VARAN technology is open and can be used by anyone
