Benefits of technology

This patented technology improves upon existing systems for managing power supply networks used within large-scale nuclear facilities such as coal plants or oil refineries. It allows operators to set up different configurations based on their needs without having direct access from outside sources like external devices (IoT). By configuring specific functions into these tools that work together correctly, they can ensure efficient operation while also being able to detect any issues related to incorrect settings caused during installation process. Overall, this innovation enhances safety measures and reduces costs associated therewith.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency at which software programs for industrial control systems (ICS) perform their functions during testing stages when they require modifications or changes made on multiple components within them. Current methods involve manual checks and comparison between different versions of program code files before finalizing any tests.

Embodiment

[0036] A DCS control system project includes several controllers, and the product corresponding to the visual logic configuration page in a single controller is uniformly generated in units of program organization units, and a single controller supports up to 1000 program organization unit files (POU). Such as figure 1 As shown, the specific implementation steps are as follows:

[0037] S1: Read the controller list DPU, the number of controllers is M, set i=0;

[0038] S2: Network connection controller DPU[i], if the connection is unsuccessful, then i=i+1, continue to connect to the next controller;

[0039] S3: Query to obtain the POU number list of the controller DPU[i], the total number of POUs is N, and j=0;

[0040] S4: Send the debugging data of DPU[i].POU[j] to the controller, the configuration tool receives the debugging data sent by the controller, analyzes the debugging data of the current program organization unit, and fills the debugging data into the correspondi...

Abstract

The invention discloses a configuration consistency check processing method for a DCS (Distributed Control System), which comprises the following steps: a configuration tool of the DCS is successively connected with a controller of the DCS, a configuration file in the controller is uploaded to the configuration tool, and the configuration tool analyzes a function block parameter in the configuration file; the configuration tool obtains debugging data uploaded by the controller; a local function block parameter in the configuration tool is compared with a function block parameter in the configuration file obtained by analysis, and information that the function block parameter is inconsistent is obtained; and the local debugging data in the configuration tool is compared with the debugging data uploaded by the controller to obtain the information of the inconsistent debugging data. The problem of inconsistent configuration parameters can be eliminated, the engineering debugging efficiency is improved, and potential safety hazards are eliminated.
