Configuration data online downloading method and device and electronic equipment

Abstract

The embodiment of the invention provides a configuration data online downloading method and device and electronic equipment, and the method comprises the steps of enabling an upper computer to compile to obtain first updating information of a first self-defined function block and second updating information of a first function block instance, under the condition that a second address indicated by the second update information does not conform to the position where the first function block instance currently stored in the memory of the controller is located, copying the currently stored first function block instance to the position indicated by the second address, respectively updating first storage information of the first custom function block and second storage information of the first function block instance; and according to the updated first storage information and second storage information, updating data of the first custom function block and the first function block instance are downloaded to the memory of the controller in an online manner, so that when the custom function block is updated, online downloading of related configuration data is realized, data hopping is not generated. Therefore, stability and the efficiency of system operation are improved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a method, device and electronic equipment for online downloading of configuration data. Background technique [0002] Distributed Control System (DCS) is an industrial control system commonly used in modern industrial sites, and it is equipped with mature industrial control configuration software. During the operation of the DCS, it is necessary to maintain the DCS, and adjust the configuration data of the industrial control configuration software according to the on-site operation conditions, so that the DCS system can work in the best state. [0003] In the actual production process, it is generally required that the industrial controller can work continuously and stably. When adjusting the configuration data, the industrial equipment cannot be disturbed, so the online download method is generally used. And allocate independent and relatively fixed memory space for e...
