BUS NODE AND CONTROL SYSTEM FOR CONTROLLING A WORK MACHINE

摘要

The invention relates to a bus node for an electric coupling of a bus system (3) to a functional module arrangement (6), having an electronic circuit for converting electrical signals between a bus protocol provided by the bus system (3) and an internal communications protocol provided by the functional module arrangement (6), and having a first coupling means (32, 33) for electrically connecting the electronic circuit to the functional module arrangement (6) and having a second coupling means (36, 37) for electrically connecting the electronic circuit to the bus system (3). According to the invention the first coupling means (32, 33) comprises a first contact means (33) that is designed for directly electrically contacting an earth connection (26) of the functional module arrangement (6).
