A bus arrangement includes a coordinator, a first subscriber having a first optical display, a second subscriber having a second optical display, a third subscriber having a third optical display, and a bus that couples the coordinator to the first, second, and third subscribers. In a standard operating phase, the first subscriber is configured to display first local information of the first subscriber on the first optical display, the second subscriber is configured to display second local information of the second subscriber on the second optical display, and the third subscriber is configured to display third local information of the third subscriber on the third optical display. The coordinator is configured to switch from a standard operating phase to a display operating phase based on detecting a fault in the first subscriber.

A bus arrangement includes a coordinator, a first subscriber, a first subscriber arrangement, and a bus. The first subscriber arrangement has a second subscriber. The bus couples the coordinator with the first subscriber and the second subscriber. The first subscriber is arranged between the coordinator and the second subscriber on the bus. The bus arrangement is configured such that the first subscriber arrangement can be decoupled from the bus in an operating phase, and such that the first subscriber cannot be decoupled from the bus in the operating phase.

Bus arrangement and method for operating a bus arrangement

A media converter has an electrical bus port for connecting a first electrical bus; and an optical bus port for connecting an optical bus. The media converter is configured to convert an electrical signal of the first electrical bus into an optical signal of the optical bus in such a way that, at a first value of an internal control signal of the media converter, the optical signal corresponds to the electrical signal and, at a second value of the internal control signal, the optical signal has an inverted shape corresponding to the electrical signal. In a transmission phase during which the internal control signal changes from the first value to the second value, the media converter is configured to emit the optical signal in such a way that the optical signal corresponds to the electrical signal until the end of the transmission phase.

A bus arrangement includes a coordinator having a coordinator address; a first subscriber having a first subscriber address; and a bus, which couples the coordinator to the first subscriber. The first subscriber is configured to receive an information message from the coordinator in a configuration phase, to extract the coordinator address from the information message, and to establish and store a safety address as a function of the first subscriber address and the coordinator address.

A bus arrangement includes a coordinator; a first subscriber; a first subscriber arrangement with a second subscriber; and a bus. The bus couples the coordinator with the first subscriber and the second subscriber. The first subscriber is arranged between the coordinator and the second subscriber on the bus. The bus arrangement is configured such that the first subscriber arrangement can be decoupled from the bus in an operating phase, and such that the first subscriber cannot be decoupled from the bus in the operating phase.

A bus arrangement includes a first subscriber, which includes a base module and a first number N of modules; a second subscriber; a coordinator, which includes a first bus terminal and a second bus terminal; and a bus that couples the first bus terminal with the first subscriber and the second subscriber. The coordinator is configured such that, in a configuration phase (K), it sends the first subscriber a first bus telegram for requesting information, the first subscriber being configured to transmit the first number N to the coordinator. The coordinator is configured to receive a fieldbus telegram via the second bus terminal and to convert the field bus telegram into a second bus telegram that is directed to the base module or to a module from the first number N of modules and to transmit the second bus telegram via the first bus terminal.

A bus arrangement includes a coordinator that has a non-volatile memory; a first node that has a first serial number; a second node that has a second serial number; and a bus. The bus includes a first signal line, which couples the first node and the coordinator; a second signal line, which connects the second node to the first node; and at least one bus line, which connects the coordinator to the first and the second nodes. The coordinator is configured such that, in a configuration phase, it establishes a connection to the first node, queries the first serial number, and stores the first serial number in the non-volatile memory, and establishes a connection to the second node, queries the second serial number, and stores the second serial number in the non-volatile memory.

System and method for bus arrangement communications

A bus arrangement includes: a coordinator; a first subscriber; a second subscriber; and a bus. The bus includes: a first signal line coupling the first subscriber and the coordinator; a second signal line connecting the second subscriber to the first subscriber; and at least one bus line connecting the coordinator to the first subscriber and the second subscriber. The coordinator is configured to send a message via the at least one bus line to the second subscriber with a command to activate the first subscriber via the second signal line. The first subscriber includes a first current sensor and the second subscriber includes a switchable current source. The second signal line couples the first current sensor with the switchable current source.
