Controller configuration downloading method based on upper and lower computer configuration difference identification

Abstract

The invention discloses a controller configuration downloading method based on upper and lower computer configuration difference identification, which comprises the following steps of: reading a first file of a controller so as to obtain a configuration file list of the controller and a first file abstract corresponding to each configuration file; determining a to-be-downloaded configuration file based on a comparison result of the first file abstract and a second file abstract in the upper computer, and generating a third file based on the to-be-downloaded configuration file; downloading the configuration file to be downloaded and a third file to a controller; according to the controller configuration downloading method based on upper and lower computer configuration difference identification provided by the invention, the modified file is obtained by comparing the MD5 abstract of the file, so that the downloaded content is identified, and only the service corresponding to the downloaded file is notified after downloading. Therefore, other services are not disturbed.

Description

technical field [0001] The invention relates to the field of industrial automation intelligent control, in particular to a controller configuration download method based on the identification of upper and lower computer configuration differences. Background technique [0002] At present, the configuration download of the controller in the field of industrial control is to record the configuration modification flag according to the operation, and perform the corresponding operation according to the modification, addition, deletion and modification of the configuration item during downloading. [0003] However, the scheme using the difference flag needs to consider many situations, the code is complex, difficult to maintain, and prone to defects. In addition, only the difference information of the current latest version can be recorded. When dealing with scenarios such as configuration version switching and rollback, it is impossible to download only accurate update informatio...

Problems solved by technology

[0003] However, with the scheme of difference flags, there are many situations to be considered, the code complexity is large, it is difficult to maintain, and it is prone to defects

In addition, only the difference information of the latest version can be recorded. When dealing with scenarios such as configuration version switching and rollback, it is impossible to only download accurate update information, which will cause the download operation to interfere with the operation of field devices.
