PURPOSE:To change a sequence control program easily and to shorten the stop time of the 2nd unit at the change of the program by arranging the 1st unit preparing the sequence control program separably from the 2nd unit controlling the driving of a body to be controlled. CONSTITUTION:While moving a cursor on a CRT display device 8, respective marks and characters are successively inputted by operating a keyboard 6 to form a relay sequence on a screen. At that time, mark data corresponding to respective marks are successively stored in an RAM5. When a program preparation command is inputted from the keyboard 6, a CPU3 prepares a sequence control program in the RAM5 on the basis of a program stored in an ROM4 and stores the prepared program in a floppy disc. In the 2nd unit 2, a CPU11 executes the sequence control program transferred and stored to/in an RAM13 repeatedly under the control of an OS in an ROM12. In said execution process, control data are successively outputted to an output circuit 20 to control the driving of the body to be controlled. |
