MEMORY SYSTEM OF SEQUENCE CONTROLLER

摘要

PURPOSE:To simplify the program by writing a data written in a memory in a controller to a memory of an external storage device and writing it to other memory in the controller so as to eliminate the need for confirmation of end of write. CONSTITUTION:Storage memory images 7, 8 are provided in the inside of a machine tool sequence controller 3 in addition to a sequence memory 6. A data written in the image 7 is inputted to a machine tool controller 2 through a line 10 and written in a storage memory 9 in an external storge device 4 through a line 11. The data of the memory 9 is written in the image 8 of the controller 3 via a line 12, the controller 2 and a line 13. Thus, the images 7, 8 are coincident with the state of the memory 9.
