Abstract: A directly taught sequence control system performs the steps of storing as a pattern information and in order of steps of operation of a load so as to superpose data one on another, one information block of real time data which includes a binary load control signal and all of pulse signals fed back in a parallel manner from detectors on the load to be controlled in accordance with the load control signal every step of operation of the load whereby a successive sequence program is formed to control the operation of the load; and successively renewing the sequence program by comparing the next real time data fed back on operation of the load while the sequence program is reproduced with the reference data which includes the data fed back from the load to be stored whereby a programing operation on a desk is unnecessary.
