Installation bus system with device for changing bus substation's operating system, has programmer for connection to bus connection elements of substation device disconnected from bus

摘要

The device has a bus (3) with at least one substation (7) connected via bus connection elements (4) with a microcontroller (10) with integral flash memory for storing an operating system. Bus substations are equipped to change the operating system or parts of the operating system by changing the contents of the flash memory after disconnection from the bus and connection of a programmer (5) to the bus connection elements of the substation device.
