fieldbus exchange format (automotive) (FIBEX)

Fieldbus Exchange Format (FIBEX) is a data exchange format defined by the Association for Standardization of Automation and Measuring Systems ( ASAM) between tools working with message-oriented bus communication systems.

Fibex can combine complex communication systems into one file with a uniform format. It is a description language based on the Extensible Markup Language(XML) that contains all the information needed to describe a complete car wiring system. This includes the topology, configuration parameters, schedules, frames and signals up to their encoding on bit level. It also supports communication systems in which different fieldbuses are used between which data exchange must take place.

As a standardized description language, Fibex simplifies data exchange between all parties involved in a project. Fibex files can be very large and complex and can contain 200 or more parameters. In version 3.0 Fibex received some structural additions. In addition to the MOST specification, protocol data units( PDU) consisting of user and control data were introduced. As a result, Fibex also supports AUTOSAR.
