Address-generator for network module e.g. in vehicle - generates individual address for modules within local area network using comparators coupled to passive components

摘要

A network module (10) is coupled to a bus communication system (12) via a control area network, CAN, stage (14) that carries out a comparison of a received address with that internally generated (16). A bidirectional link is provided to the central control stage (20) and this also connects with a drive stage (24) and sensor unit (24). The multibit address generator has a pair of stages that are in the form of comparators, coupled to passive components. The outputs connect with an oscillator driven division circuit. ADVANTAGE - Simple construction insensitive to disturbances.
