PURPOSE:To cope with wide-range requests to the scale and functions of a sequence controller in a short time, by recording control instructions on a cassette tape to facilitate changing control instructions. CONSTITUTION:A tape where control instructions are recorded is set to a cassette 5, and a generating part 19 for a control instruction reproduing command signal is operated to generate the command signal. When this command signal is inputted, an instruction execution controlling part 16 interrupts an executing processing and controls the cassette 5 through data transmission and receiving parts 11 and 3 and a controlling part 4 to reproduce control instructions. Said generating part 19 gives the signal to a reproduced data converting part 13 to report that data to be inputted hereafter is control instructions. Control instructions reproduced from the cassette 5 are inputted to the reproduced data converting part 13 through data transmission and receiving parts 3 and 11 and have the signal mode converted and are written in a control instruction storage part 15. |
