Abstract
PURPOSE: To make it possible to display contents of input, output and operation memories even in a sequence controller operating time by selecting the address of a signal, which should be monitored, by a setting equipment.
CONSTITUTION: Contents of program memory 3 are read out seccessively from zero address 0 to maximum address n at the oscillation period of oscillator 1 according to contents of program counter 2, and contents of instruction part OP are sent to operation part 4 through instruction bus 14, and contents of address part Ad are transmitted to input part 5, output part 6 and operation memory 7 as the operation result through address bus 15. When the address of setting epuipment 9 which sets an address to be monitored and the address read out from memory 3 through bus 15 agree with each other, coincidence circuit 8 sends a signal to memory circuit 10; and since circuit 19 stores the current signal stage of input data line 12 and output data line 13, circuit 10 lights display epuipment 11 when signals from circuit 8 exist.
