Subprogram calls by MSTB code and macro program calls by G code, M code, etc. are performed. Further, there is a case where multiple sub-programs are called from among the sub-programs called in the main program.

[0003]

A machining program becomes larger and more complicated as the number of called subprograms and macro programs is increased, and as the number of calls becomes multiple, the machining program becomes larger and more complicated. It gets harder.

In addition, the subprogram is not called due to the misuse of the calling code, an alarm occurs because there is no program to be called, or the called program is wrong. There was a problem that it might not be noticed.

The present invention has been made in view of the above points, and has a function of grasping the whole picture of a machining program and checking the constraint violation of the program before actually machining. It is an object to provide a program configuration display method for a numerical control device.

[0006]

In order to solve the above problems, the present invention provides a program configuration display system for a numerical control device having a function of displaying a calling relationship between a plurality of programs and checking a constraint violation of calling programs. In, call code search means to search the specified program to see if there is a call code,
Program search means for checking whether the program called by the retrieved call code exists in the internal or external memory, code content search means for examining the content of the call code, and the program search means and the code content search means Alarm content retrieval means for retrieving erroneous content when not retrieved, display means for displaying the configuration of the designated program and a program called from this program, and the erroneous content retrieved by the alarm content retrieval means And a program configuration display method for a numerical control device.

[0007]

According to the above-mentioned means, the calling code searching means searches the designated program for the calling code, and the program searching means searches for the program called by the calling code. The code content search means searches the code and the usage of the code for errors, and the alarm content search means searches and displays the alarm content when an error is found by the program search means or the code content search means. The means displays the program structure or alarm content.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a program configuration display system of a numerical controller according to the present invention. In this figure, there is a program 1 which is a program configuration display target. This program 1 constitutes the main program of the machining program and is designated from a plurality of programs.

The program configuration display system of the numerical controller comprises a calling code retrieval means 2, a program retrieval means 3, a code content retrieval means 4, an alarm content retrieval means 5 and a display means 6. The calling code search means 2 searches the designated program 1 and searches the program 1 for a calling code. The program search means 3 checks whether or not there is a program called by the calling code searched by the code search means 2, and searches for a program in the internal or external memory 7. Here, if the program called by the calling code does not exist in the memory 7, an alarm is issued. The code content retrieval means 4 retrieves whether the calling code is used correctly. Here, if the calling code is used incorrectly, an alarm is issued. The alarm content retrieval means 5 retrieves the error content from the alarms issued by the program retrieval means 3 and the code content retrieval means 4. Display means 6
Displays the configuration of the designated program 1 and the program called from this program 1 and the content of the error retrieved by the alarm content retrieval means 5.

FIG. 2 is a flow chart showing the processing for searching the contents of the program. When searching the contents of a program by the program structure display method, first, the calling code in the program is searched (step S
1). Next, as a result of the search in step S1, it is determined whether or not there is a calling code in the program (step S2). If there is no call code in the retrieved program, the process directly goes to the display process.

If it is determined in step S2 that there is a calling code, the code and the called program are searched (step S3). Since the called program can be placed not only in the internal memory (RAM) of the numerical controller but also in the external memory such as a floppy disk or a data cassette, these programs are also searched. Then, it is judged whether or not there is a called program (step S4). If the called program does not exist in the internal or external memory, the alarm contents are searched (step S5) and the process proceeds to the display process. .

If it is determined in step S4 that there is a called program, then the contents of the code are searched (step S6). As a result of the content search, it is determined whether or not there is an error in the code (step S7), and if there is an error in the code, the alarm content is searched (step S8), and the process proceeds to the display process.

If there is no error in the code in the determination in step S7, it is determined whether there is any error in the usage of the code (step S9). If there is no error in the usage of the code, the process proceeds to the display process. If the usage of the code is incorrect, the alarm content is searched (step S1).
