Industrial control graphical programming environment running state data monitoring system and method

Abstract

The present invention relates to a system and method for monitoring the operating state data of an industrial control graphical programming environment. The graphical program is built in the upper computer, and a memory allocation list is formed according to the storage structure of the graphical program. After compiling, the execution code and memory The allocation linked list is downloaded to the target machine; the target machine creates the main thread and the background thread, the main thread initializes the interpreter and executes the execution code periodically, and the background thread is responsible for interacting with the host computer; the host computer sends the data to the corresponding target machine according to the configuration information Dynamic monitoring command message; the target machine switches to the background thread to receive the dynamic monitoring command message after the end of the main thread code execution cycle, parses the command message, collects monitoring data and sends the data group package to the host computer , real-time dynamic refresh display. The invention realizes the real-time dynamic refreshing of monitoring data during the program running process, and the dynamic refreshing monitoring function does not affect the execution function of the control program.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a system and method for monitoring operating state data of an industrial control graphical programming environment. Background technique [0002] Compared with traditional programming languages, graphical programming adopts the concept of "data flow", so that the program design can also complete the program writing while completing the flow chart, and the user does not need to be familiar with hardware implementation and specific text-based programming According to the rules of the language, you only need to understand the functions realized by each graphical programming component, and according to the design requirements of the target object, configure, arrange and lock the graphical programming components to complete the complex application programming design, so it is simple The intuitive graphical programming method is also more and more favored by users in the field ...

AI Technical Summary

Problems solved by technology

If the execution result fails to meet expectations, it is difficult to judge which link has a problem

[0005] Graphical programming software with display components can dynamically view components and variables, but the program needs to be recompiled when replacing the components to be displayed, which reduces the efficiency of graphical program development; and after the industrial automation program is running normally, it is often not allowed to recompile the program. compile

[0006] Special debugging methods such as serial port printing, emulator debugging, etc. are generally only used in the early design and development, and the on-site operators often do not have these professional debugging skills
