Abstract: The present invention relates to an integrated circuit device for controlling LIN slave nodes based on a control signal transmitted by a LIN master control device. The IC device comprises a slave node circuit for processing the control signal when received in the form of a LIN message frame via a first data line terminal. The IC device also comprises a master node circuit for processing further control signals to be transmitted in the form of LIN message frames via a second data line terminal to the LIN slave nodes. The IC device also comprises a processing unit for controlling the LIN slave nodes based on the control signal by composing the further control signals.

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.

Abstract: A lighting system includes a plurality of nodes arranged in a serial network. The lighting system has a master node, one or more gateway nodes, a first communication bus connecting the one or more gateway nodes to the master node, a plurality of slave nodes such that each slave node is connected to a lighting source and is arranged for conveying data messages, and one or more second communication buses, each connecting one of the gateway nodes with one or more slave nodes of the plurality. The master node is arranged for conveying a unique network address to the one or more gateway nodes via the first communication bus, and the one or more gateway nodes are arranged for conveying a unique network address to the plurality of slave nodes via one of the second communication buses. At least one gateway node is arranged for storing a lighting plan for lighting one or more slave nodes connected to that gateway node.

Abstract: A method of operating a plurality of driving units for powering electronic units comprises interchanging a data frame including a bit sequence, between a master control unit and at least one of a plurality of driving units at slave nodes. A step of applying an ID field comprises indicating the driving unit address using a first bit sub-string comprising N bits, allowing the master control unit to identify whether data should be received or transmitted, or allowing each addressed driving unit to decode which action is required by the master control unit, using an R/T command bit, performing a length decoding step, for including information in the ID field regarding the type of instructions included in the data frame, using an F function bit, and assigning data bits to different electronic units or indicating in the length of the bit string in the data field, using a second bit sub-string.
