Abstract

The invention provides a data sharing method applied among multiple virtual controllers. The method comprises the steps that virtual controller software is arranged, and function simulation of multiple virtual controllers is achieved by adopting a multi-engine mode; the virtual controller software is used for executing a control configuration program which is programmed by a user of an upper computer and conducting real-time monitoring and on-line modifying on data obtained in the calculation process of the control configuration program; the multi-engine mode is implemented through the steps that multiple software execution environments capable of driving the control configuration program to conduct calculation is constructed by loading and running multiple calculation engine programs in a physical computer, and then function simulation of the virtual controllers is achieved. According to the data sharing method, the technical problems that among nodes of the virtual controllers of an industrial control system, the data synchronization efficiency is poor, and the resource sharing degree is low are solved.

Description

technical field [0001] The invention relates to the technical field of industrial automation control, in particular to a data sharing method among multiple virtual controllers. Background technique [0002] In large-scale industrial control systems, virtual simulation platform is widely used because it can highly realistically simulate the dynamic operation of real control systems. At present, all major industrial control system manufacturers embed virtual controller software in their industrial control software products. The so-called virtual controller software, its main function is to virtualize the hardware functions of industrial field controllers, instead of physical control The controller completes the calculation and communication tasks of the control configuration. With the help of this software, users can debug and correct the control configuration program written by themselves in advance, and then import the program into the actual control system for use. This me...
