A Realization Method of Configuration Debugger for Virtual Controller

Abstract

Provided in the present invention is a configuration debugger implementation method for use with a virtual controller, the method comprising: storing algorithm logic of a virtual controller as a logic configuration page and a sequence which is sequentially stored by a module in the page, and accordingly defining a configuration breakpoint data structure; defining a logic configuration page file on the basis of a modular storage structure, and monitoring real-time data of a virtual controller; on the basis of the foregoing, implementing a breakpoint configuration function of a debugger by means of issuing configuration breakpoint information; at the same time, defining a configuration breakpoint list in the virtual controller, storing the configuration breakpoint information, and when executing a control algorithm simulation, determining whether a breakpoint is hit by means of traversing the configuration breakpoint list, and deciding whether the simulation is paused; the virtual controller converting page-by-page, module-by-module, and next-step debugging instruction information which is issued by debugging software into a temporary configuration breakpoint, and implementing said debugging instruction functions according to breakpoint hit logic; when debugging ends, the debugging software issuing an instruction to clear the configuration breakpoint list in the virtual controller.

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
