Abstract

PURPOSE:To easily execute programming to various handlings in the course of sequence operation, by providing a program corresponding to an interruption input. CONSTITUTION:A program memory 6 is divided into an area which is related to an interruption processing, and an area which is not related to said processing. It is operated as a general controller at a usual time when there is no interruption input. When a changeover handling, etc. occur in the course of sequence operation, they are handled as an interruption input. An interruption analyzer 8 saves contents of an address pointer 5 of a program which is being executed at present, into a save buffer 7, analyzes the inerruption input simultaneously, decides a program corresponding to the interruption input, sets an address to the address pointer 5, and executes a sequence corresponding to the interruption.
