Bus system and method for assigning addresses to peripheral units
First Claim
1. A bus system comprising:
- a bus controller;
a bus wiring comprising at least one bus line and connected at one end to said bus controller;
a number of connectors for peripheral units arranged in series along said bus wiring;
a number of peripheral units each connected to a respective connector on said bus wiring;
wherein, said bus system is designed in such a way that, as long as a peripheral unit has not been connected to a given connector, communication in said at least one bus line downstream of this connector is interrupted, and that upon connection to a peripheral unit communication in said at least one bus line is restored at this connector; and
wherein said bus controller comprises means for detecting a default-addressed peripheral unit on said bus wiring and assigning an address thereto.

Abstract
A bus system (10) comprises a bus controller (12) and a bus wiring (14) comprising at least one bus line (16) and connected at one end to the bus controller (12). A number of connectors (221 . . . 224) for peripheral units (24) are arranged in series along the bus wiring (14) and a number of peripheral units (24) are each connected to a respective connector (22i) on the bus wiring (14). The bus system (10) is designed in such a way that, as long as a peripheral unit (24) has not been connected to a given connector (22i), communication in the at least one bus line (16) downstream of this connector (22i) is interrupted, and that upon connection to a peripheral unit (24) communication in the at least one bus line (16) is restored at this connector (22i). The bus controller (12) comprises means for detecting a default-addressed peripheral unit (24) on the bus wiring (14) and assigning an address thereto.

7. A method for assigning an address to peripheral units in a bus system, said bus system comprising a bus controller and a bus wiring including at least one bus line and connected at one end to said bus controller, a number of connectors for peripheral units being arranged in series along said bus wiring;
- said bus system being designed so that said at least one line of said bus wiring is interrupted at each connector that is not connected to a respective peripheral unit, and that upon connection of a respective peripheral unit said line is restored;
said method comprising the steps of;
(a) detecting the presence of a default-addressed peripheral unit in the bus system;
(b) upon detection of a default-addressed peripheral unit, assigning an address to said non-identified peripheral unit. - View Dependent Claims (8, 9, 10, 11, 12, 13)
- said bus system being designed so that said at least one line of said bus wiring is interrupted at each connector that is not connected to a respective peripheral unit, and that upon connection of a respective peripheral unit said line is restored;
