Abstract
The invention relates to a single-channel digital communication bus system and to a station for use in such system. Only a single physical interconnection between the stations is present for transferring the data. Bit synchronization is effected either in that the data is self-clocking or by a second, clock lead. The data channel realizes an AND-function. The transmission of a message by a master station is answered by an addressed slave by an acknowledge signal train. The acknowledge signal train has a plurality of bits, inclusive of error protection bits. Error protection may be effected by transmitting a series of mutually identical bits, or by means of a CRC signal subtrain. The acknowledge may be positive, negative or a 'no acknowledge' signal train.
