    Abstract: A method for autoconfiguration of a plurality of nodes in a linear network allows extracting the address and position of each node. The method includes applying an identifier field for transmitting to the bus the bit sequence of the identifier of a chosen node. Then for at least for the first node to the last but one node, a field comprising a predetermined bit sequence is applied. The field comprises dominant bits, so a current is transmitted. Then, a further field is applied for transmitting any stored direction bit associated to that node and obtained in any previous iteration. The iteration continues by choosing a node different from a node chosen in any previous cycle, starting the communication, until all nodes are identified.

    Abstract: A transmitter for establishing communication between a device and a differential network bus includes current driving means connected to each of the two conduction lines of the differential network bus, through a first and second conduction paths of the transmitter; at least one unidirectional current regulator for extracting a first current equal to a known ratio of a parasitic current circulating through the first conduction path, with a direction inverse to the driving current through the conduction path connected to one of the lines of the differential bus; means for obtaining, from the first current, a second current with a magnitude equal to the original magnitude of the parasitic current; and means for introducing the second current into the second conduction path connected to the other line of the differential bus.

    Abstract: A method for autoconfiguration of a plurality of nodes in a linear network allows extracting the address and position of each node. The nodes are identified by a unique identifier. The method comprises choosing a node in a network and extracting its identifier, and for the first node to the last but one node, transmitting a current in the network from the chosen node, and reading the direction of the current flowing through at least the nodes not chosen in previous iteration cycles. The identifier is linked with the direction of the current for said not chosen nodes, obtaining the position of said not chosen nodes relative to the chosen node. These steps are repeated by choosing a different node not chosen before. Autoconfiguration is finished when the identifier of each node is extracted, and the physical position of each node is determined.

    Abstract: A system having a plurality of devices configured in a daisy chain network including a communication bus connecting the devices and adapted to exchange address-setting information. Each device includes an input pin adapted to receive via an input signal line different from the communication bus a signal comprising configuration information for configuring at least the device; a configuration handling unit adapted to detect a configuration mode and to configure the device according to the configuration information; an indicator adapted to indicate whether the configuration handling unit has finished configuring the device; an output pin adapted to forward the configuration information to the daisy chain network when the indicator indicates the configuration of the device is done; and a safety handling unit adapted to be operable in a safety handling mode when the indicator indicates the configuration of the device is done.
