Machining center PLC integration method

Abstract

The invention relates to a machining center PLC integration method. A function selection module is connected with an input and output filtering processing module, an input and output logic processing module and an internal memory, and controls program contents in a form of byte with the input and output filtering processing module, the input and output logic processing module and the internal memory so as to form a machining center PLC integration system capable of realizing module functions according to needs of the outside. The machining center PLC integration method has the advantages of completely and uniquely mapping physical addresses into the internal memory in the input and output filtering processing module, precisely processing the positive negative logic and forced logic of the physical addresses in the input and output logic processing module, saving scanning time and shortening execution period; and a program control and manual control mixed programming module is a main part of an entire PLC, and the art of programming of the program control and manual control mixed programming module is directly related to the level of integration and also determines the compactness and intensiveness of the logic of the entire PLC.

Description

technical field [0001] The invention belongs to the field of numerical control machining centers and motion control, and mainly relates to a PLC integration method of a machining center. Background technique [0002] At present, the logical control programming methods of most CNC machine tool manufacturers for their products are basically based on the characteristics of the controlled objects to compile sequential programs that meet their control requirements one by one, which will greatly increase the number of program steps, which is not conducive to real-time control. There are also a small number of designers who make relatively independent program blocks with the same function and different logic in a small range. This program block can be called unlimited times, which is an improvement over the previous one. However, different input and output interfaces correspond to different PLCs. version, making debugging and maintenance more difficult. However, as a specific log...

[0002] At present, the logical control programming methods of most CNC machine tool manufacturers for their products are basically based on the characteristics of the controlled objects to compile sequential programs that meet their control requirements one by one, which will greatly increase the number of program steps, which is not conducive to real-time control

There are also a small number of designers who make relatively independent program blocks with the same function and different logic in a small range. This program block can be called unlimited times, which is an improvement over the previous one. However, different input and output interfaces correspond to different PLCs. version, making debugging and maintenance more difficult

However, as a specific logic control of a machining center, no one has designed its logic with PLC logic integration to quickly switch between different interfaces and solve the problem of quick debugging.
