Abstract
A bus system has a daisy-chain configuration. The bus system includes a master unit and a plurality of slave units that are serially connected to the master unit downstream thereof via a line system. A first one of the slave units first connected downstream of the master unit is configured to invert a request signal, which is provided by the master unit and received via a first line section of the line system, and to output the inverted request signal on a second line section of the line system leading to an adjacent, second one of the slave units.
Claims15
A bus system having a daisy-chain configuration, the bus system comprising:
- a master unit;
- and
- a plurality of slave units that are serially connected to the master unit downstream thereof via a line system, a first one of the slave units first connected downstream of the master unit being configured to invert a request signal, which is provided by the master unit and received via a first line section of the line system, and to output the inverted request signal on a second line section of the line system leading to an adjacent, second one of the slave units in the daisy-chain configuration,
- wherein the bus system is configured to provide a differential signal transmission, and
- wherein the first slave unit is further configured to invert an inverted response signal, which is provided by the second slave unit and received via the second line section, and to output based thereon a non-inverted response signal on the first line section leading to the master unit.
A slave unit for a bus system, the bus system having a daisy-chain configuration and including a master unit, to which a plurality of slave units are serially connectable downstream thereof via a line system, the slave unit being configured to:
- invert a request signal, which is provided by the master unit and received via a first line section of the line system;
- and
- output the inverted request signal on a second line section of the line system leading to an adjacent, second one of the slave units in the daisy-chain configuration,
- wherein the slave unit is configured to provide a differential signal transmission, and
- wherein the slave unit is further configured to invert an inverted response signal, which is provided by the second slave unit and received via the second line section, and to output based thereon a non-inverted response signal on the first line section leading to the master unit.
A bus system having a daisy-chain configuration, the bus system comprising:
- a master unit;
- and
- a plurality of slave units that are serially connected to the master unit downstream thereof via a line system, a first one of the slave units first connected downstream of the master unit being configured to invert a request signal, which is provided by the master unit and received via a first line section of the line system, and to output the inverted request signal on a second line section of the line system leading to an adjacent, second one of the slave units in the daisy-chain configuration,
- wherein the bus system is configured to provide a differential signal transmission, and
- wherein the second slave unit is configured to:
- invert the inverted request signal, which is output by the first slave unit and received via the second line section, and to output based thereon a non-inverted request signal on a third line section of the line system leading to an adjacent, third one of the slave units;
- and/or
- invert a non-inverted response signal, which is provided by the third slave unit and received via the third line section, and to output the same as an inverted response signal on the second line section leading to the first slave unit.
A bus system having a daisy-chain configuration, the bus system comprising:
- a master unit;
- and
- a plurality of slave units that are serially connected to the master unit downstream thereof via a line system, a first one of the slave units first connected downstream of the master unit being configured to invert a request signal, which is provided by the master unit and received via a first line section of the line system, and to output the inverted request signal on a second line section of the line system leading to an adjacent, second one of the slave units in the daisy-chain configuration,
- wherein the bus system is configured to provide a differential signal transmission, and
- wherein the master unit and the slave units are configured in such a way that a response signal from the second slave unit on the second line section is inverted and a response signal from the first slave unit on the first line section is non-inverted.
