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 device includes a master device, a set of slave devices and a bus. The master device is configured to transmit first messages carrying a set of operation data message portions indicative of operations for implementation by slave devices of the set of slave devices, and second messages addressed to slave devices in the set of slave devices. The second messages convey identifiers identifying respective ones of the slave devices to which the second messages are addressed requesting respective reactions towards the master device within respective expected reaction intervals. The slave devices are configured to receive the first messages transmitted from the master device, read respective operation data message portions in the set of operation data message portions, implement respective operations as a function of the respective operation data message portions read, and receive the second messages transmitted from the master device.

A dynamically addressable master-slave system and a method for dynamically addressing slave units includes a master unit and a plurality of slave units, such that the slave units are interconnected with the master unit via a bus system. The respective network addresses of the slave units are assigned to the respective serial numbers of these slave units in a table in the master unit according to the position thereof in the system according to a determined order. Upon replacement of slave units, a list of serial numbers of the units to be replaced is transferred to the master unit in the sequence of the acquisition of the serial numbers, which master unit replaces these serial numbers in the table with the serial numbers of the replaced slave units transmitted to the master unit.

The invention relates to a system and to a method for identifying a compression roller column in a tableting machine having a machine processor. The system includes a plug-in connection which includes a receiving socket and a plug. The plug has at least one embedded controller, and data can be exchanged between the machine processor of the tableting machine and the embedded controller of the plug via the one plug-in connection. The plug and the receiving socket are arranged on the tableting machine. The plug can be connected to the receiving socket.

The invention relates to an arrangement and a method performing data exchange between various integrated circuits, IC, (3,4,5,6,7) in an automotive control system wherein the data are exchanged by a bus and has the object to enable ASIL C/D system coverage and to tie various ICs (clocks, regulators, memory interfaces, sensor signal conditioners, power management ICs etc.) This is solved the data are exchanged by a bus being ASIL C/D compliant and forming a common protocol to exchange information among the integrated circuits (3,4,5,6,7). The method is solved by functions implemented within the bus as setting the frequency of operation; arbitrating roles of the integrated circuits as master or slave device; checking integrity of exchanged data; frame repetition; detecting bus stuck- at failure modes; filtering or denouncing failures and warnings from peripheral devices; detecting remote out of specification local clock; and monitoring and predicting system reliability and profiling maintenance events.
