PURPOSE:To monitor simply a programmable controller by providing a number display switch transferring a number stored in a number storage device to a display storage section again and commanding the display of a display device. CONSTITUTION:A number inputted from a number switch 5 is stored in a number storage section 4, transferred to a display storage section 6 and displayed on a display device 7. In depressing a state display switch 3, a control section 2 transfers the state of the number from the state memory 1 to the storage section 6 and the state is displayed on the display 7. In switching the display to the number display, when the number display switch 8 is depressed, the number is written from the storage section 4 to the storage section 6 and the number is displayed automatically on the display 7. Then when the stage display is desired to be observed again and the state display switch 3 is depressed, since the state is stored in the memory 1, the display is attained again. |
