Abstract

The invention discloses a programmable logic control language compiling method and device. The method comprises the steps that a corresponding first debugging information table is generated according to a text language of a programmable logic control (PLC) language, wherein the debugging information table comprises variables of the text language and a first syntax tree; a corresponding second debugging information table is generated according to the graphic language of the PLC language, wherein the second debugging information table comprises a second syntax tree of the graphic language; and a coding instruction is generated according to the first debugging information table and the second debugging information table. The technical problems that the ST text language of the programmable logic control language in the related technology cannot be directly recognized and executed by the controller and the logicality is poor are solved.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to a programming logic control language compiling method and device. Background technique [0002] With the diversification of industrial application requirements, the traditional programmable logic control PLC (Programmable Logic Controller) is weak in the field of calculation and motion control. The advent of ST structured text high-level language satisfies this demand very well. Structured text language ST (Structured text) is a high-level language similar to pascal. For developers familiar with high-level computer languages, ST language is easy to learn, easy to use, flexible to use, fast and efficient. However, in the related art, the ST language cannot be recognized and executed by the controller, and needs to be converted into an IL instruction set, which is similar to assembly language to be used by the controller, and the logic is poor. [0003] For the above problems, no...
