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, a ring-type MOST network installed in a vehicle, a plurality of units— a master unit (M) as well as a plurality of slave units oo (S)— are networked, preferably through an optical data bus (D), and connected through supply lines (L) to a central voltage source such as the on-board battery of the et) vehicle. In order to enhance the operational reliability, error diagnostics, and overall performance of the network, data are also transmitted through the supply lines (L)—for example, diagnostic data for error diagnostics or update data to update the individual units (M, S). The invention is especially suited for use in a motor vehicle.
