Abstract
A bus device that has recently been connected to a bus system is first addressable at a pre-set address. A bus master transmits a new address and an identification to the bus device. The bus device compares the transmitted identification with an identification that has been stored in the bus device and assumes the transmitted new address, if the transmitted identification corresponds with the identification that has been stored in the bus device. The bus device is then addressable at the new address.
Claims21
An address assignment method for at least one bus device that has been newly connected to a bus system, comprising:
- transmitting a new address and an identification from a bus master to a bus device initially addressable at a pre-set address;
- comparing, at the bus device, the identification transmitted from the bus master with a preset identification stored in the bus device;
- and
- assuming, at the bus device, the new address transmitted from the bus master, if the identification transmitted from the bus master corresponds to the preset identification stored in the bus device, so that the bus device is subsequently addressable at the new address.
At least one computer readable medium storing a program to control a bus master to perform a method comprising:
- transmitting a new address and an identification from a bus master to a bus device initially addressable at a pre-set address;
- comparing, at the bus device, the identification transmitted from the bus master with a preset identification stored in the bus device;
- and
- assuming, at the bus device, the new address transmitted from the bus master, if the identification transmitted from the bus master corresponds to the preset identification stored in the bus device, so that the bus device is subsequently addressable at the new address.
A bus master connected via a bus system to at least one bus device that has been newly connected to the bus system, comprising:
- an output unit to transmit a new address and an identification to a bus device initially addressable at a pre-set address, the bus device comparing the identification transmitted from said bus master with a preset identification stored in the bus device and assuming the new address transmitted from said bus master, if the identification transmitted from said bus master corresponds to the preset identification stored in the bus device, so that the bus device is subsequently addressable at the new address.
A bus device newly connected via a bus system to a bus master, comprising:
- an input unit to receive a new address and an identification from a bus master to a bus device initially addressable at a pre-set address;
- at least one storage unit to store a preset identification;
- and
- a processing unit to compare the identification transmitted from the bus master with the preset identification and to assume the new address transmitted from the bus master, if the identification transmitted from the bus master corresponds to the preset identification stored in said at least one storage unit, so that said bus device is subsequently addressable at the new address.
