METHOD FOR CONTROLLING A PLURALITY OF UNITS NETWORKED TO GIVE A NETWORK, AND NETWORK COMPRISING A PLURALITY OF NETWORKED UNITS

摘要

In a network, for example an annular MOST network mounted in a vehicle, a plurality of units one master unit (M) and a plurality of slave units (S) are networked via a preferably optical data bus (D) and linked with a central voltage source, for example the vehicle battery (B), via supply lines (L). In order to improve operational safety, error diagnosis and the general capacity of the network, the supply lines (L) are also used to transmit data, for example diagnostic data for the purpose of error diagnosis or update data for updating the individual units (M, S). The invention is especially suitable for use in a motor vehicle.
