Abstract

PURPOSE:To check the halfway course of the sequence program, by counting up the program counter by every one step and by displaying the operation result at that time. CONSTITUTION:When an arbitrary value is indicated to check indicating circuit 4, the advance of program counter 3 is stopped with this value, and after that, counter 3 is counted up by every one step by the command of indicating circuit 4. Operation control part 5 reads an instruction word from memory 1 by the address indicated by program counter 3, and various data are taken in from machine tool 10 through input unit 9 according to the instruction word and are output through output unit 8 after subjected to prescribed operations. Since the operation result is displayed on display circuit 6, it can be checked whether the program is correct or not.
