User interface between a flexray communication component and a flexray user, and process for transmitting messages over said interface

A user interface (204) is arranged between a FlexRay communication component (100) connected to a Flex-Ray communication line (101) over which messages are transmitted and which comprises a message memory (300) for temporarily storing messages from the FlexRay communication line (101) or for the FlexRay communication line (101), and a user (102) associated with the FlexRay communication component (100). In order to ensure a particularly resource-saving and resource-sparing connection between the user (102) and the FlexRay communication component (100), the user interface (204) comprises an arrangement (800) for the temporary storage of messages. The arrangement (800) comprises at least one message memory (802) having a first connection (804) to the FlexRay communication component (100) and a second connection (806) to the user (102).; The message memory (802) is preferably designed as a dual-ported RAM.
