Problems solved by technology

[0003] With the continuous improvement of the level of industrial automation control, the calculation process of the logic configuration file in the distributed control system is complex and the demand for data interaction between process controllers is also increasing. The logic of data interaction between multiple process controllers It is not simple, the communication between the controllers is complicated, the logic is difficult, and the real-time performance is poor. Therefore, when parsing the logic configuration file, how to update the reference points between the controllers in real time is a problem that needs to be solved

Embodiment approach

[0045] Such as figure 1 As shown, the present invention is a kind of multi-task cycle-oriented data interaction method, comprising the following steps:

[0046] Obtain the basic information of the source controller stored in the local controller;

[0047] According to the basic information, request the source-end controller to register and configure the reference point belonging to the source-end controller in the local controller, and analyze the data response message returned by the source-end controller; The data information and the result of analysis are stored in the inter-controller data interaction queue corresponding to the reference point, and the corresponding flag bit of the reference point is updated;

[0048] Load the corresponding reference point in the inter-controller data interaction queue to the corresponding position in the algorithm page to participate in the operation, and clear the updated flag of the reference point after the operation is completed.

Embodiment

[0052] Such as figure 1 As shown, the present invention is a kind of multi-task cycle-oriented data interaction method, comprising the following steps:

[0053] S1, enter the inter-controller data interaction cycle, traverse all other source controllers i in the stored domain in the local controller, and obtain the basic information of the source controller i stored in the local controller;

[0054] The acquisition process is as follows: the basic information includes the reference points of the source controller i referenced by the local controller, the IP address of the source controller i, the network link status of the source controller i, the group state change flag cfgFlag, and judge the number of reference points, network link status and configuration change flag cfgFlag of the referenced source controller i.

[0055] Further, judging the number of reference points, network link status and configuration change flag cfgFlag of the referenced source controller i specific...

Abstract

The present invention provides a data interaction method, system, device and storage medium oriented to a multi-task cycle, including fetching the basic information of the source controller stored in the local controller; requesting the source controller to register and configure the local controller The reference point data belonging to the source controller and parse the data response message returned by the source controller; after the parsing is completed, the data information and the parsed results of the reference point are stored in the inter-controller data interaction queue corresponding to the reference point and Update the corresponding flag of the reference point; traverse the next source controller after the processing is completed; load the reference point in the corresponding data interaction queue between controllers to the corresponding position in the algorithm page to participate in the operation, and clear the reference after the operation is completed Click the updated flag. The method can realize that the local controller efficiently periodically requests reference point data from other source controllers based on the algorithm task period, so that the data displayed by the local controller is more reliable.

Description

technical field [0001] The invention belongs to the technical field of controller data processing, and in particular relates to a multi-task cycle-oriented data interaction method, system, device and storage medium. Background technique [0002] A Distributed Control System (DCS) is a control system specially designed to control complex, large-scale applications in industrial processes. The controller is the brain of the distributed control system, which controls the various parts geographically distributed in the control area, and executes the control algorithms and configurations of various devices, and handles the network communication between the engineering PCs, which passes simplex or redundant Additional configuration is implemented to better control the performance of complex processes. The reliability, stability, and high timeliness of the controller are the guarantees for the high reliability, flexibility, coordination, and stability of the distributed control sys...
