Communication entity for communicating over a bus oriented communication network

摘要

The entity has a control device constructed to communicate via a bus-oriented communications network in response to a selection signal according to one of communications bus sub-systems e.g. point-to-point system and multi-drop system. A selection device generates the selection signal as a function of an operating mode of the entity in order to select one of the sub-systems. A common hardware connection unit communicates via the sub-systems. The selection device is constructed to select the subsystems in two operating modes for transmission of process data and/or parameter data. An independent claim is also included for a bus communications system comprising two wiring arrangements for connecting communications entities according to communications bus sub-systems.
