Abstract

PURPOSE:To realize not only a small size but a low cost for the sequence control device, by actuating the sequence control device with the rewritable memory in a program writing device. CONSTITUTION:The sequence is supplied with every symbol and by the key switch 5 of the program writing device 3 and then converted into the object code by the processor 12. When the symbol is supplied, the mode switch 20 turns on and off the gate 16 and the gate 17, respectively. Thus the symbol is written into the rewritable memory 6 via the gate 16. In the control mode, the switch 20 turns off and on the gates 16 and 17. Thus a connection is given between the address bus and the data bus of the memory 6 and the instruction execution part 18 within the sequence control device 1 via the IC socket 2 and the gate 17, and an operation is given based on the contents of the memory 6.
