Abstract
A bus system with an address conductor and a status conductor onto which there are connected mutually parallel stations with programmable address decoders and with status decoders and/or status encoders, whereby the address conductor carries a sequence of address informations and the status conductor status informations timewise associated therewith. The bus system is essentially so constructed whereby the address conductor carries mutually spaced serially binary coded bit patterns of presently m address bits (address-bit pattern m), and the status conductor which is displaced relative to the address-bit pattern carries a serial bit pattern of r status bits (status-bit pattern r).
