Embodiment Construction

[0018] Please refer to figure 1 Shown, a kind of control strategy configuration syntax error automatic detection method of the present invention comprises the following steps:

[0019] Step 10, judging whether all logical pages of the control strategy configuration have been saved, if not, then proceed to step 20 after saving; if yes, then directly proceed to step 20;

[0020] Step 20, determine the object to be analyzed in the control strategy configuration, the object of the analysis includes: a logical page (that is, a certain diagram in the system), a loop, and the entire system; the entire system is composed of multiple loops, the The circuit is composed of several logic pages (the logic page is the smallest unit of control logic, and each logic page is edited by different types of configuration components; the function of analyzing the logic page is to analyze each The configuration element performs syntax analysis, and displays the error information in the information ...

Abstract

The invention provides a method for automatically detecting a syntax error in a control policy configuration. The method comprises the following steps of: 1, judging whether all logic pages of the control policy configuration are stored; 2, determining an object to be analyzed in the control policy configuration; 3, scanning connecting lines of all edited configuration elements in the analyzed object, wherein the configuration elements comprise an input element, an output element, a policy element and an auxiliary element; 4, analyzing attribute parameters of all configuration elements in the analyzed object, the input and output of the elements, and data streams of the elements one by one; 5, displaying an analysis result of the analyzed object; and 6, judging whether all logic pages are analyzed, if a certain logic page is not analyzed, executing the step 4, and if all logic pages are analyzed, finishing operation. By adoption of the method, the logic pages, a loop and a system of the control policy configuration are subjected to syntax analysis scanning, occurrence of logics which do not accord with a syntax rule in the logic can be quickly determined, and error / alarm information is displayed on an information output window.

Description

【Technical field】 [0001] The invention relates to the technical field of industrial automation software, in particular to an automatic detection method for grammatical errors generated in the editing process of control strategy configuration components. 【Background technique】 [0002] Control strategy configuration refers to the use of intuitive programming methods (ladder diagram, function module diagram, etc.), to complete the generation of control strategy or monitoring strategy program. At present, the most widely used system control strategy configuration software is the upper software part of the distributed control system for the PLC system. It is the interface between the user and the system, and completes the logical configuration of the field equipment in the control system, thereby realizing the control of the system. It is an integral part of the system. [0003] Control strategy configuration based on graphical components is the most common development method f...
