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 ...
