A method and device for encapsulating and reusing configuration data in an industrial control system

Abstract

The invention discloses a method for encapsulating and reusing configuration data in an industrial control system, including: S1, editing configuration data attributes based on application requirements; S2, encapsulating and exporting configuration data based on a preset template; S3, exporting The packaged configuration data is read back for verification; S4, importing the configuration data. Among them, the readback verification includes reading back the exported configuration data by itself, and checking and verifying with the configuration data before exporting through CRC. A device for data encapsulation and reuse in industrial control systems is also proposed, including support for configuration data Reuse, improve the efficiency of engineering configuration configuration, prevent illegal tampering of configuration data content, and perform correct integrity checks on data export and import that may be tampered with.

Description

technical field [0001] The invention relates to the field of industrial process control, in particular to a method and device for encapsulating and reusing configuration data in an industrial control system. Background technique [0002] In an industrial control system, a complete control system is composed of multiple sites, the configuration data of the same site is composed of different sub-configuration data, and the sub-configuration data is composed of smaller configuration units. For example, the control station configuration is composed of control logic configuration, hardware configuration and variable configuration. The hardware configuration is divided into module configuration, signal point configuration and communication configuration, and the communication configuration is divided into modbus communication group. Modbus configuration is divided into master station and slave station configuration. Part of the functional configuration data for each station is la...

Problems solved by technology

Changing and removing unnecessary data on a large scale requires a large amount of engineering; at the same time, the configuration data in the industrial control system is highly correlated. Such an implementation process may affect the reused part of the configuration data. Engineering volume, but may increase additional engineering volume

[0004] In addition, some control systems also have the encapsulation of small-grained configuration data, but the encapsulated data is opaque and cannot be viewed or edited by the user. There will be certain limitations, and it is impossible to compare and edit in real time, and the effect is not good
