The invention provides an implementation method of a logic breakpoint debugging function for an industrial control system. The implementation method comprises the steps: utilizing logic minimum execution units to divide algorithm logic, and setting debugging state variables at each minimum execution unit; and completing logic interruption by calling the related functional functions, and maintaining the interface display during the process for running and debugging by debugging the corresponding relationship between the state variables and the minimum execution units. The implementation method specifically includes the steps: realizing setting and deleting of breakpoints in the algorithm program, including breakpoint setting and deleting of the text and graphical algorithm logic; during the executing process of the program, providing a debugging method for running to a breakpoint Run to and a single step Step In / Step Over; and displaying the running state in the configuration interface of the algorithm program. The implementation method of a logic breakpoint debugging function for an industrial control system can realize the logic breakpoint debugging function for an industrial control system, and can guarantee the correctness and stability of algorithm logic.
Description
technical field [0001] The invention belongs to the technical field of industrial automation control systems, and more specifically relates to a method for realizing a logic breakpoint debugging function of an industrial control system. Background technique [0002] In industrial automation control, the control system composed of configuration software and controller (also known as upper computer and lower computer) is widely used in various control fields: such as distributed control system (DCS), programmable logic controller (PLC) )Wait. The configuration software is responsible for generating the algorithm program, and the controller is responsible for executing the program to realize the control function. In many applications, the algorithm program has a certain complexity, and the correctness of the algorithm program is directly related to the correctness and safety of industrial control. Therefore, it is of great significance to provide a set of accurate and efficie...
