Abstract: In a straight and circular knitter, a control arrangement for supplying information upon needle selection on circulation knitting carriages includes a central control station provided with a main computer storing all information for controlling the knitting machine. Each knitting carriage is equipped with a control unit including an auxiliary computer, an end stage for operating the needles and a bus control circuit. The main computer is connected to respective circulating control units via a slide contact track and contact shoes coupled to respective auxiliary computers. The microprocessors in respective control units are interconnected by a bus including a transmitting line, a receiving and a bus control line. The bus control line forms with the bus control circuits and microcomputers of respective control units a closed loop which controls the transmission of error data to the main computer in the event that an error is detected in a control unit.
