Abstract

PURPOSE:To easily judge whether a parameter is a standard one or a nonstandard one at the time of maintenance or at the time of setting the parameter by displaying data different from the standard parameter on a display screen so as to be discriminable. CONSTITUTION:In a display screen 10, the standard parameter in a numerical controller is indicated, and a parameter number 11 and data 12 to indicate the meaning of the parameter are displayed. When the standard parameter in the screen 10 is reset according to a machine tool to be the control object of the numerical controller, to the four nonstandard parameters at parameter numbers 03, 06, 08 and 10, which are different from the standard parameter, out of the set parameters in a set parameter screen 13, underlines 14 to 17 are applied. Thus, the standard parameter can be easily discriminated from the nonstandard parameter only by observing the screen 13.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a numerical control device for controlling a machine tool, and more particularly to a numerical control device that has improved parameter input/output methods and display methods.

[Conventional technology]

A single control system such as a numerical control unit (CNC) or a PC (programmable controller) is used to control a large number of machine tools with different specifications.

As machine tools, etc. become more and more diverse as mentioned in 2, numerous parameters are added to the numerical control devices that control them.
It is necessary to set parameters corresponding to the machine tool, etc.

Recent numerical control devices have standard parameters internally. Normally, these standard parameters can be set and used as they are with simple operations. However, in reality, there are many cases where a part of these standard parameters is changed and used, that is, data different from the standard parameters (non-standard parameters) is set and used.

[Problem to be solved by the invention]

Although conventional numerical control devices have standard parameters inside and can be set with simple operations,
When a non-standard parameter is set, it is not possible to output only that non-standard parameter to an external storage medium; all data including the standard parameter (both standard and non-standard parameters) must be output. , there was a lot of waste. In other words, general-purpose numerical control devices have a large number of parameters, but in actual use, they often use parameters that differ only slightly from the standard parameters, and all data must be exported for maintenance purposes. There is a problem in that it is wasteful to save data on a storage medium and it takes time to output the data.

Furthermore, when malfunctions occur due to incorrect parameter settings, the programmer must display them on the screen and investigate the cause. Many of these setting errors are due to non-standard parameters. Therefore, programmers try to examine non-standard parameters first. However, the parameters displayed on the screen are simply a list of numbers and numerical values, and it is very difficult to intuitively determine whether they are standard parameters or non-standard parameters. Therefore, programmers and others referred to instruction manuals and other documents to investigate the cause. That is, when a malfunction occurs due to a parameter setting error, it is difficult to determine which parameter setting is incorrect, and it takes time to investigate the cause.

A first object of the present invention is to provide a numerical control device that can save parameters in an external storage medium in a short time.

The second object of the present invention is to:
It is an object of the present invention to provide a numerical control device that can easily determine whether a parameter is a standard parameter or a non-standard parameter.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides a numerical control device having standard parameters therein, which performs input/output operations of only data different from the standard parameters to and from an external storage medium. is provided.

Moreover, in order to solve the above-mentioned problem, the present invention provides a numerical control device that has standard parameters inside and can set them on a display screen. There is provided a numerical control device characterized in that the information is displayed on the display screen in a distinguishable manner.

[Effect]

When saving parameters to an external storage medium for maintenance purposes, only data that differs from standard parameters (non-standard parameters) on the external storage medium is subject to input/output operations, reducing the time required for the operation. .

In addition, when a malfunction occurs due to a parameter setting error and maintenance is performed, data that differs from standard parameters (non-standard parameters) can be easily identified, so the data can be investigated first and the cause can be determined at an early stage.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 2 shows a schematic configuration diagram of the hardware of a numerical control device for implementing the present invention. In the figure, 1 is a processor that controls the entire numerical control device, 2 is a ROM in which a system program is stored, and 3 is a RAM in which various data are stored. 4 is a display device, and a CRT or the like is used. Reference numeral 5 denotes a non-volatile memory in which a program, parameters, pinch error correction amounts, etc. are stored. 6 is an operation panel, and 7 is a machine tool. 8 is an external input/output interface consisting of R3232-C. Reference numeral 9 denotes an external storage medium, through which parameters are manually output via an external input/output interface 8.

FIGS. 1(a) and 1(b) are diagrams showing an example of a display screen for explaining an embodiment of the present invention.

A display screen 10 in FIG. 1(a) shows standard parameters within the numerical control device. Number 11 indicates the parameter number. Data 12 indicates the meaning of the parameter, l'OJ or fi
It is expressed as a numerical value of J.

Parameter number 01 means the size of the minimum setting unit when inputting in millimeters, and in the case of data
In the case of J, it means that 0.01 mm was set respectively. In this embodiment, data fQJ is set in advance as a standard parameter. Standard parameters for parameter numbers 02 to 40 are similarly set in advance as shown in the figure, depending on the meaning of each parameter.

FIG. 1(b) shows a display screen of set parameters when the standard parameters on the display screen 10 are reset according to the machine tool to be controlled by the numerical control device. Among the setting parameters on the display screen 13, those that are different from standard parameters (non-standard parameters) have parameter number 03.06.
．． There are four on 08.10. In this example, for these four non-standard parameters, the underline (underline) 1
4.15.16 and 17 are attached and displayed.

This makes it possible to easily distinguish between standard parameters and non-standard parameters just by looking at the display screen 13.

Instead of underlining, standard parameters may be displayed as they are in white, and only non-standard parameters may be displayed in red, for example, by changing the color.
Also, only the non-standard parameters may be displayed in a different color from other display characters. Furthermore, only the non-standard parameters may be displayed blinking.

As long as the standard parameters and non-standard parameters are displayed on the display screen in a distinguishable manner, the essence of the present invention remains the same regardless of the method used.

The above parameter display process will be explained using the flowchart of FIG. In the figure, the number following S indicates the step number.

[S1] Determine whether parameter display has been selected. If the parameter display is selected, the process advances to S2, and if it is not selected, the process ends.

[S2] Set variable N to 1.

[S3] Read out the Nth parameter from the setting parameters.

(S4) Determine whether the Nth parameter has a value different from the standard parameter. That is, it is determined whether the Nth parameter is a standard parameter or a non-standard parameter. Then, if the values are different (non-standard parameters), go to S5, and if the values are not different (standard parameters), go to S6.
Proceed to.

(The 353N parameter (non-standard parameter) is displayed in red.

(S6) Set the Nth parameter (standard parameter) to white (
(general font color on the display screen).

[S7] Add 1 to variable N.

(S8) It is determined whether or not the Nth parameter exists for N, which is incremented by 1 in step 37. If it exists, the process advances to S3; if it does not exist, it ends.

In the above flowchart, we have explained the case where standard parameters and non-standard parameters are displayed in different colors so that they can be distinguished. However, when displaying them with underlines or blinking, S5 It is only necessary to change the contents of S6 according to the operation.

Next, the process of inputting/outputting parameters to/from the external storage medium 9 via the external input/output interface 8 will be described using the flowchart shown in FIG.

Sl, S2, S3, S4, S7 and S8 are the third
Since it is the same as the one shown in the figure, the explanation will be omitted.

The difference between this figure and Figure 3 is that in S4, if the Nth parameter is a value different from the standard parameter (non-standard parameter), the process advances to S56, and if it is a value that is not different (standard parameter), the process directly advances to S7. It's on the point of moving forward. Then, in 356, the Nth parameter (non-standard parameter) is output to the external storage medium 9 via the external output interface 8.

Through the above processing, only the non-standard parameters are output to and stored in the external storage medium 9.

In the above embodiment, the case where one data is set for one parameter number has been explained, but some numerical control devices allocate 8 bits of data to one parameter number. . This type of parameter will be explained below using FIGS. 5(a) and 5(b).

In the figure, a display screen 30 shows standard parameters within the numerical control device, and a display screen 33 shows setting parameters obtained by resetting the standard parameters of the display screen 30 according to the machine tool to be controlled by the numerical control device.

Among the setting parameters on the display screen 33, there are two parameter numbers, 03 and 05, that are different from standard parameters (non-standard parameters).

However, non-standard parameters on the data are underlined (
These are the six parts marked 34, 35, 36 and 37 (underlined).

Therefore, for parameters such as those in this example, the first
Rather than underlining the parameter number and its data as shown in the figure, it is easier to distinguish between the two by underlining and displaying only the non-standard parameter data. Further, only the non-standard parameters may be changed in color or blinked.

Regarding the input/output processing of the external storage medium 9, there are two methods: one is to store all the data with parameter numbers 03 and 05, and the other is to store only the data with underlines 34, 35, 36 and 37. The street can be considered. In either method, it is not necessary to store the data of the non-standard parameters and the standard parameters, so the time required for the operation can be shortened. If only the underlined portion is to be stored, the parameter number and the position information within the 8-bit data may be stored at the same time.

〔Effect of the invention〕

As explained above, according to the present invention, when saving parameters to an external storage medium for maintenance, only data different from standard parameters (non-standard parameters) is output, so there is no waste and time is saved. be.

In addition, even if a malfunction occurs due to a parameter setting error, data that differs from standard parameters (non-standard parameters)
If you investigate the problem first, it will take less time to find out the cause.
