PURPOSE:To read an execution state of IL from a local display, too, by adding a state of an output inhibiting signal by an interlock IL instruction, to input/output staes by a logical operation result in case when the instruction is executed, and executing its monitor display. CONSTITUTION:A monitor device 2 inputs a program address range for specifying an instruction group to be monitored by a keyboard 8, and transmits its data to a transfer part 5 of a controller CTL1 from a transfer part 10. The CTL1 receives it, stores a monitor data regarding an instruction being within a program address range designated when the instruction is executed, in buffer memory of the transfer part 5, and transfers the monitor data to the transfer part 10 without discontinuing the operation of a main control part 3. The monitor data consists of a logical operation result in case when the instruction is executed, and a status data by an output inhibiting signal controlled by an IL instruction, and the device 2 decodes the monitor data by a display control part 7, and display an RADA diagram obtained by adding a state of the output inhibiting signal to input/output states, on a CRT6. |
