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 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.
