Abstract
PURPOSE:To display information on overlapping use by making an automatic check on the overlapping use of a program stored in the program memory of a sequence controller employing arithmetic processing on a repetitive arithmetic system. CONSTITUTION:According to the contents of address counter 2, a program is read out of program memory 4 of a sequence controller and then transferred to output instruction detecting circuit 5, which decides whether the instruction of it is output one and when not, address-up indicating circuit 11 is put into operation to indicate the next address through the counting-up operation of address counter 2. Once the output instruction is detected, its number is transferred to output-number use checking circuit 7 and according to the number, memory part 9 is read out to checks whether the instruction has been used. As a result, when so, a signal is supplied to overlapping-use state display converting circuit 13 and while the overlapping use state is displayed on display part 15, the contents of counter 2 are displayed via converting circuit 14.
