Embodiment Construction

[0014] The present invention will be further described below.

[0015] The invention discloses a general PLC platform, which comprises a conversion module, an editing module, a compiling module, a modular calling module, a communication module and a symbol table module.

[0016] The conversion module is the most important functional module of the general platform. This module mainly realizes the conversion function between Siemens, Mitsubishi, Omron and IEC61131-3 standard PLC languages.

[0017] The editing module is the most basic functional module of the general platform, which mainly provides a program editing environment for the mnemonic language instructions of the PLC. Its function is not only able to accept the input of the user program, but also to be able to edit the input text.

[0018] The compilation module compiles the user program written in mnemonic language, prompts the user for errors in the program, and finally generates executable files that can run on vari...

Abstract

The invention relates to the field of industrial control, in particular to a PLC universal platform and a design method thereof. The PLC universal platform comprises a conversion module, an editing module, a compiling module, a modular calling module, a communication module and a symbol table module. The design method of the PLC universal platform includes the steps of symbol table design, modular design, program conversion design and communication design. Thus, the universal platform can be used for PLCs of many manufacturers, the transportability of PLC programs among different machine types can be improved, burdens on engineering technicians and engineering designers can be relieved, the PLC universal platform has practical industrial application value, and the situation that the compatibility of the PLCs of the manufacturers is poor at present can be alleviated to some extent.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to a general PLC platform and a design method thereof. Background technique [0002] Programmable logic controller (Prograble Logic Controller, referred to as PLC) has gone through more than 40 years of history, with its compact structure, high reliability, strong function, fast speed and other advantages, it has been widely used and has become the mainstream of industrial control systems. With the development of semiconductor technology, computer technology and communication technology, the field of industrial control has undergone earth-shaking changes, and PLC is also constantly developing and changing. PLC constantly adopts new technologies and continuously enhances the functions and openness of the system. [0003] Due to the advantages of PLC in various aspects, it has been widely used in petrochemical, power electronics, electrical appliances, metallurgy, machinery manufactu...
