Input processing from the external storage device 23, such as reading the machining program PRO2, is executed one after another. The main control section 2 performs drive control of the actuator 25 via the above-mentioned machining operation control section 19 as foreground processing, and performs drive control of the actuator 25 via the above-mentioned processing operation control section 19, and performs drive control of the actuator 25 via the above-mentioned external I/O processing section 12 from the external storage device 23. Input processing for machining program PRO2 and the like is performed as background processing. Further, the main control unit 2 detects the “processing item” currently being processed via the external I/O processing unit 12, and notifies the window processing unit 5 of the “processing item”. Then, via the window processing section 5, a request is made to the real screen data generation processing section 7 to "display a cursor" regarding the "processing item". The main control unit 2 then generates an external I/O window displayed on the external I/O window screen BD' of the screen display device 22 via the screen data generation processing unit 7 and the screen display processing unit 16, as shown in FIG. A blinking cursor CR is displayed at the display position of the external I/O processing item data BI related to the "processing item" in the /O processing item data BI. Therefore, the screen display device 22 of the control panel 20 displays the position screen FD' related to machining operation control and the machining program P from the external storage device 23.
Since the external I/O window screen BD' related to input processing such as RO2 is displayed in a composite manner at the same time, the operator can perform operations related to machining operation control as foreground processing, while also performing operations on external storage device 23 as background processing. It is possible to suitably monitor the input processing of the machining program PRO2, etc. from the computer without switching the display screen of the screen display device 22 as in the conventional case. Note that after the input processing of the machining program PRO2 etc. from the external storage device 23 has started, the operator

That is, as will be described later, the external I/O window screen BD' is not deleted from the screen display device 22 until the input processing from the external storage device 23 is completed. It is possible to suitably monitor input processing such as the following.

[0014] When the input processing of the machining program PRO2 etc. from the external storage device 23 is completed, the main control unit 2
detects “end of input processing” via external I/O processing unit 12, and transmits “end of input processing” to window processing unit 5.
Notify. Then, via the window processing section 5, it requests the real screen data generation processing section 7 to "erase the external I/O window screen BD' displayed on the screen display device 22." Then, among the position screen data FD and external I/O window screen data BD written in the real screen data memory 9, the external I/O window screen data BD is deleted via the real screen data generation processing section 7. , the contents of the real screen data memory 9 are changed to only the position screen data FD. Then, the main control section 2 reads out the position screen data FD from the real screen data memory 9 at any time via the screen display processing section 16, and displays only the position screen data FD as the position screen FD' as shown in FIG. is displayed on the screen display device 22 as follows. That is, when input processing of the machining program PRO2 etc. from the external storage device 23 is completed, the screen display device 22 of the control panel 20
As shown in FIG. 7, the position screen FD' and the external I
The external I/O window screen BD' is erased from the state in which the /O window screen BD' is simultaneously displayed in a composite manner, and a state in which only the position screen FD' is displayed as shown in FIG. 3 is reached. Therefore, the operator can suitably monitor the completion of reading of the machining program PRO2 etc. from the external storage device 23 without switching the display screen of the screen display device 22 as in the conventional case.

In the above embodiment, when reading the machining program PRO2 etc. from the external storage device 23,
That is, the case where input processing to the external storage device 23 is performed has been described, but when performing output processing to the external storage device 23, the external I/O window screen BD' related to the output processing is similarly set to the position screen FD.
' etc. can be displayed in a composite manner on the screen display device 23 at the same time. In addition, in the above embodiment, in order to simplify the explanation, as soon as input/output processing to the external storage device 23 is completed, the external I/O window screen BD'
has been described above from the screen display device 22, but if predetermined conditions are met, the external I/O window screen BD' will not be deleted even if input/output processing to the external storage device 23 is completed. Alternatively, it may be displayed as is on the screen display device 22. In other words, after the menu key 21b at the left end of FIG. Assuming that input/output processing to the device 23 is to be performed again, the external storage device 2
Even if the input/output processing for 3 is completed, the external I/O window screen BD' may be displayed as is on the screen display device 22. In this case, only the highlighted display of the menu MN3 shown in FIG. 7 is erased, and the operator is notified that the input/output processing for the external storage device 23 has been completed.

Therefore, on the screen display device 22 of the control panel 20, an external I/O window screen BD' related to input/output processing to the external storage device 23, which is performed as background processing, is displayed corresponding to the progress of the input/output processing. In this way, the position screen FD' related to machining operation control performed as foreground processing can be displayed in a composite manner at the same time, so the operator can display the background screen without switching the display screen of the screen display device 22 as in the conventional Input/output processing for the external storage device 23 performed as ground processing can be conveniently monitored.
