Bus component device has a sub-divided integrated flash memory, so that operating system and application programs can be altered, expanded or corrected without disconnection of the device from the bus

摘要

Method for alteration, expansion and error correction of stored data in a microcontroller (20) of a bus component (10), whereby a connection is made via a bus (30), especially a European installation bus, so that a new operating system, or parts thereof, or a new application program can be stored in a flash memory (50) that is subdivided into memory segments (5.1-5.n). An Independent claim is made for a bus component device for connection to an EIB system.
