AUTBUS Technology

AUTBUS can be used with balanced cables such as single-pair twisted-pair cables or unbalanced cables such as coaxial cables. With a qualified twisted pair cable, up to 254 multi-drop data network nodes can be reached over a distance of up to 500 meters, at a transmission speed of 100Mbit/s at the same time.

On physical layer, AUTBUS uses OFDM technology (Orthogonal Frequency Division Multiplexing) to adapt to severe channel conditions and against narrow-band co-channel interference which make AUTBUS a perfect solution for industrial communication technology in hash environment. OFDM technology has been used in wired and wireless communication. With its characteristics of broadband, low latency and determination, AUTBUS is predestined for the field of industrial wired data communication. The mission-critical deterministic challenges exist in a variety of industrial applications for which the AUTBUS can be of great benefit.

As AUTBUS is using time-based frame to synchronize each node, it can easily achieve accurate time synchronization result (less than 100ns) without complicated software protocol like IEEE 1588.

AUTBUS supports data tunnelling, with which, for example, Ethernet-based transmission protocols such as traditional Ethernet, PROFINET, EtherNet/IP, ModbusTCP, and other communication protocols like CAN, UART, LIN/FR can be transmitted from one data connection point to another via the multi-drop data network without having to translate these protocols.

AUTBUS can transmit IPv4/IPv6 data and at the same time enables the transmission of time-sensitive and non-time-sensitive data as a virtual bus. It’s an ideal solution for transmit periodic data together with burst data on a same bus without complex synchronization and management protocols.
