Machine control apparatus capable of treating plc interface with program and treatment method thereof

Abstract

PROBLEM TO BE SOLVED: To improve user's convenience, easiness of design, and stability of the system, by easily constituting, without wiring, an I / O means for PLC (Programmable Logic Controller) for a non-sequential control command of a main operation panel of a controller for a machine tool, by processing it using a software system without using another contact and another lamp. SOLUTION: In the controller 300 for the machine tool capable of performing software PLC contact processing and its processing method, the non-sequential control command to be processed by a PLC 330 is not transmitted through the regular PLC input contact, but is transmitted in a method in which it is directly inputted into a memory for the PLC through the main operation panel 310 and a numerical control section 320. The control result is displayed on the main operation panel 310 by being transmitted to the numerical control section 320 in a preset predetermined method without using the regular PLC output contact.

Description

technical field [0001] The invention relates to a machine tool control device and an interface processing method that can be used for PLC interface processing with a program, especially for the I / O on the programmable logic controller (Programmable Logic Controller: hereinafter referred to as PLC) of the main operation panel (Operation Panel) of the machine tool. The method does not use an interface or an indicator light, but uses a program to process, thereby forming a machine tool control device and a processing method that can perform PLC interface processing with a program that does not require wiring. Background technique [0002] CNC (Computer Numerical Control: Computer Numerical Control) machine tools currently in use refer to equipment that performs machining operations such as cutting on workpieces through automatic operations controlled by NC programs.

Problems solved by technology

This wiring can sometimes act as a transmission path or antenna for clutter that occurs in the machine tool and its controls, degrading the machine tool performance, and the wiring process constrains the machine tool design

[0015] In addition, with the recent increase in the price of I / O interfaces, the installation of switching elements for various machine tool controls has become more and more expensive.

Moreover, installing this switch element on the main operating panel makes the main operating panel larger and larger, and the design of the main operating panel is also limited by these switches and indicator lights.
