Method for implementing configuration debugger of virtual controller

Abstract

The invention provides a method for implementing a configuration debugger of a virtual controller. The method comprises the following steps: storing the algorithm logic of the virtual controller as the sequence of sequential storage of logical configuration pages and in-page modules, and defining a configuration breakpoint data structure accordingly; defining a logical configuration page file based on a modular storage structure and monitoring real-time data of the virtual controller; on the basis, realizing a breakpoint setting function of a debugger by issuing the configuration breakpoint information; meanwhile, defining a configuration breakpoint list in the virtual controller, storing the configuration breakpoint information, when performing the control algorithm simulation, determining whether a breakpoint is hit or not and determining whether the simulation is suspended by traversing the configuration breakpoint list; when issuing page-by-page, module-by-module, and next-step debugging instruction information by debugging software, converting the information into a temporary configuration breakpoint by the virtual controller, and implementing these debugging instruction functions according to the breakpoint hit logic; and when the debugging is finished, issuing an instruction to clear the configured breakpoint list in the virtual controller by the debugging software.

Description

technical field [0001] The invention belongs to the field of industrial automation control, in particular to the emulation debugging of a virtual controller used in an industrial process control system. Background technique [0002] In the field of industrial process control, virtual controller, as the functional simulation software of industrial process controller, has the functions of simulating logic configuration and basic debugging in the controller. However, for the simulation debugging of complex control logic, only by monitoring the variable trend of its operation in real time, the debugging efficiency is often low, and it is impossible to accurately and effectively locate the defect of the logic. [0003] To solve this problem, consider adding a development debugger function in the virtual controller software. By introducing single-step debugging functions such as breakpoint setting and single-step execution, the single-step and breakpoint debugging of the control ...

AI Technical Summary

Problems solved by technology

The function of the debugger implemented by this method is not comprehensive, and the insertion of stub information leads to a large change in the algorithm configuration source program before and after debugging

The inconsistency of the algorithm configuration source program will not only lead to completely different algorithm debugging results, but also bring greater disturbance to the operation of the controller

[0005] In addition, in the virtual controller software of the existing industrial control manufacturers, the debugger function is often not supported
