摘要： A programmable sequence control device for programming a control sequence by simulating the steps of a flow chart comprises a plurality of stages each of which is visually representative of a step in the flow chart and is selectively wired to other stages for simulating the flow chart. The stages comprise contact points representing output terminals, address terminal and jumping control terminal, respectively. A logic control circuit between each two stages at the respective contact points comprises first logic means producing a first output signal based on the combination of signals at the output terminal and jumping control terminal of a first stage and second logic means responsive to an address signal applied to the address terminal of another stage for producing a further output signal applied at the output terminal of the latter stage. Upon application of a starting command at a selected stage, the stages sequence through the steps simulating the operations of the intended flow chart.
