Abstract
The teachings of the present disclosure relate to bus systems. Various embodiments thereof may include bus coupling units, for example a bus coupler comprising: four ports comprising input/output connections to which bus cables of a two-wire bus are connectable, wherein both electrical energy and data are transmissible via both bus cables. The first port and second port are bus coupler-internally electrically conductively connectable by means of a first connection path. The third port and fourth port are bus coupler-internally electrically conductively connectable by means of a second connection path. The first connection path and second connection path are bus coupler-internally electrically conductively connectable by a bridge path.
Claims8
A bus coupler comprising:
- four ports comprising input/output connections to which bus cables of a two-wire bus are connectable, wherein both electrical energy and data are transmissible via both bus cables;
- a first port and a second port are bus coupler-internally electrically conductively connectable by means of a first connection path;
- a third port and a fourth port are bus coupler-internally electrically conductively connectable by means of a second connection path;
- and
- the first connection path and second connection path are bus coupler-internally electrically conductively connectable by a bridge path.
A bus system comprising at least one bus coupler with four ports comprising input/output connections to which bus cables of a two-wire bus are connectable, wherein both electrical energy and data are transmissible via both bus cables;
- a first port and a second port are bus coupler-internally electrically conductively connectable by means of a first connection path;
- a third port and a fourth port are bus coupler-internally electrically conductively connectable by means of a second connection path;
- and
- the first connection path and second connection path are bus coupler-internally electrically conductively connectable by a bridge path.
A method for operating a bus system with at least one bus coupler with four ports comprising input/output connections to which bus cables of a two-wire bus are connectable, wherein both electrical energy and data are transmissible via both bus cables;
- a first port and a second port are bus coupler-internally electrically conductively connectable by means of a first connection path;
- a third port and a fourth port are bus coupler-internally electrically conductively connectable by means of a second connection path;
- and
- the first connection path and second connection path are bus coupler-internally electrically conductively connectable by a bridge path;
- including automatically opening the bridge path of each bus coupler to carry out tests or initialization procedures.
