Abstract

PURPOSE:To perform writing or rewriting operation with an input from the screen of a visual display device by providing a memory area where a value is set or read out through software on a computer link card and performing initialization with its data pattern. CONSTITUTION:The value in the memory area 4 on the computer link card 1 is set through the software when a control panel 3 is powered on, and the value is easily rewritten according to command data sent from a host computer. Consequently, initialization is carried out not by setting setting pins as hardware again, but by checking the value rewritten through the software. Namely, the hardware such as the setting pins is unneeded and the software itself performs processing corresponding to it instead.

Description

[Detailed Description of the Invention] [Industrial Applications] The present invention provides a flexible manufacturing system (FMS) or a direct numerical control (DNC) by linking with a host computer by a computer link card (interface card). This relates to a numerical control device for operation.

[Conventional technology]

FIG. 2 is a front view of a computer link card 1 attached to a conventional numerical control device, and 2 is a setting pin on the computer link card 1. As shown in FIG.

FIG. 3 is a front view of the control panel 3 of the numerical control device;
is a computer link card housed in this control panel 3.

According to the arrangement pattern of setting bin 2 in FIG.

The processing of the software on the computer recovery card 1 is different, and soft fist initialization processing is performed according to each arrangement pattern.

[Problem that the invention seeks to solve]

The computer link card 1 in the conventional numerical control device is configured as described above.

As shown in FIG. 3, when the computer link card 1 is stored in the control panel 3, the setting pin 2 cannot be reset, and the computer link card 1 must be reset after turning off the power to the control panel 3. It was necessary to take out the computer link card 1, reset the setting bin 2, and store the computer link card 1 in the control panel 3 again.

This invention was made to solve the above problems, and the setting pin 2 on the computer link card 1
The purpose of the present invention is to eliminate the setting pin 2 and to obtain a numerical control device that can solve the problems associated with the existence of the setting pin 2.

[Means for solving problems]

The numerical control device according to the present invention eliminates the setting pin on the computer link card, and instead provides a memory area on the computer link card in which a value corresponding to the setting value of the setting pin is set or retrieved by software. Initialization is performed using a data pattern set in a memory area, and the memory area can be written or rewritten by command data from the host computer or input from the visual display screen of the numerical control device. It is.

[Effect]

The numerical control device according to the present invention can set a value corresponding to the setting value of the setting pin in the memory area on the computer link card by command data from the host computer or input from the screen of the visual display of the numerical control device. , all the complicated procedures for changing the setting pins are unnecessary.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, 1 is a computer link card used in the numerical control device of the present invention, and 4 is a memory area provided on the computer link card 1 for setting or retrieving values corresponding to the values set by the setting pins using software. .

Next, its handling and operation will be explained.

The value of the memory area 4 on the computer link card 1 in FIG. 1 is set by software when the control panel 3 in FIG. 3 is turned on, and the value is set by the command sent from the host computer. Data can be easily rewritten.

As a result, each initialization can be performed by looking at the values rewritten by the software, rather than by resetting the hardware setting pins.

In other words, the hardware itself called the setting pin is no longer necessary, and the software itself is used instead.

It became possible to perform the corresponding processing.

2. In the above embodiment, the setting values of the memory area 4 on the computer link card 1 were obtained as command data from the host computer.

Settings can also be input from the screen of a visual display such as a cathode ray tube (CRT) of a numerical control device.

〔Effect of the invention〕

As described above, according to the present invention, setting pins on the computer link card can be omitted, the hardware becomes cheaper by that much, the schedule for developing Dounia logic is shortened, and the software It is now possible to have a wide variety of setting values, which has the effect of making it possible to build much more sophisticated software.
