PURPOSE:To make it possible to display the conditions of input and output elements together with operating cycle numbers by practicing both the operating cycle numbers and the program, which is used to monitor the input and output element relating the shift of the operating cycle, together with the sequence program. CONSTITUTION:When the operation of a sequence controller is started to satisfy the starting condition of an operating cycle 1, a monitor program is practiced. When a monitor command is read out in accordance with the monitor program, signals are generated from a monitor command circuit 21. On the other hand, the data indicating the operating cycle 1 of the operation portion of the monitor command are stored in a latch 25a and displayed in an indicator 26a. In response to the output of the circuit 21 and the clocks, a counter 22 is stepwise advanced so that the input and output signals of their addresses indicated at the operation portion of the next monitor command are displayed in indicators 26b to 28d. |
