description The invention relates to a method of transferring information between microcomputers in a decentralized process control system, particularly for telephone systems. To prevent contention for possession of the information transfer bus without the need for central equipment, a simple bus system consisting of a multiwire data bus and two single-wire control buses is proposed. Bus mastership is passed on after transmission, with the address of the next transmitter being determined by each microcomputer itself and forming part of each message. Bus mastership is determined by communication of the previous transmitter and by calculations performed by the microcomputer itself.
