DEVICE FOR SOFTWARE CONTROL Russian patent published in 2000 - IPC

FIELD: automation and computer engineering, in particular, for computer-aided manufacturing. SUBSTANCE: device has duplex lines for control transmission. Goal of invention is achieved by introduced instruction memory unit, address counter, instruction register, address reception direction commutator, mode flip-flop, encoder for direction of control reception, encoder for direction of control transmission, delay counter, instruction bus, four OR gates, two AND gates, unit of triple-state gates, group of NAND gates, unit of prohibition gates and starting flip-flop. Only single physical communication line is required for interaction between any device pairs in control system. EFFECT: increased field of application due to decreased number of external inputs and outputs. 6 dwg, 1 tbl, 3 ex
