Description

Technical Field

[0001] This application relates to the field of distributed control technology, and in particular to a method, apparatus, device and storage medium for direct reference of station tag numbers. Background Technology

[0002] In medium to large-scale industrial control systems, control application data is typically distributed across multiple control stations. Therefore, inter-station communication is necessary for data exchange. Specifically, inter-station communication involves the sending station transmitting data to the receiving station using a specific communication protocol, and the receiving station receiving and using this data according to the same protocol, thus completing the data exchange. In existing technologies, indirect referencing requires users to configure a sending table at the sending station and a receiving table at the receiving station. This configuration process is complex, restrictive, and prone to errors, making inter-station tag reference difficult. Direct referencing based on the UCP protocol requires modification of the controller, limiting its support to specific controller models and further complicating inter-station tag reference.

[0003] In conclusion, how to reduce the difficulty of referencing station reference numbers is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0048] Figure 3 This is a schematic diagram of the structure of a computer device provided in an embodiment of this application. Detailed Implementation

[0049] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. This application provides a method, apparatus, device, and storage medium for direct reference of inter-station tag numbers, applicable to the field of distributed control technology. The above are merely examples and do not limit the application areas of the methods and apparatuses provided in this application.

[0050] In medium to large-scale industrial control systems, control application data is typically distributed across multiple control stations. Therefore, inter-station communication is necessary for data exchange. Specifically, inter-station communication involves the sending station transmitting data to the receiving station using a specific communication protocol, and the receiving station receiving and using this data according to the same protocol, thus completing the data exchange. In existing technologies, indirect referencing requires users to configure a sending table at the sending station and a receiving table at the receiving station. This configuration process is complex, restrictive, and prone to errors, making inter-station tag reference difficult. Direct referencing based on the UCP protocol requires modification of the controller, limiting its support to specific controller models and further complicating inter-station tag reference.

[0051] The inventors, through research, proposed the technical solution of this application. When executing this method, firstly, it is determined whether the first control station containing the referenced bit number has been detected. If so, the first inter-station communication program page of the first control station is opened. Within the first inter-station communication program page, it is searched to see if the referenced bit number exists in the data reference block connected to the first control station's transmit pin. If so, the second control station is controlled to add a bit number of the same type as the referenced bit number. Next, the second inter-station communication program page of the second control station is opened. Within the second inter-station communication program page, it is searched to find the function block pin corresponding to the first control station's function block, with the same function block number and function block pin number. Then, it is determined whether the function block pin is connected to the data reference block. If not, a data reference block is added and connected to the function block pin to reference the referenced bit number. In this way, inter-station bit number referencing is achieved and the difficulty of inter-station bit number referencing is reduced.

[0052] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application. It should be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of the present application can be combined with each other.

[0053] Before executing the embodiments of this application, it is necessary to configure an inter-station communication FBD program page, configuring various types of inter-station function blocks, with one-to-one correspondence between sending and receiving, and placing it as a template file in the installation directory. Next, modify the logic for creating a new control station to automatically copy the inter-station FBD program page template configuration file from the installation directory to the configuration directory, and rename the inter-station communication FBD program page template file to a specific name, such as "Interstation_communication_Domain_Station_Number," with one fixed file for each control station. Finally, add an "Inter-station Reference Link" module to the FBD configuration program, similar to the "Data Reference" module. Users who want to reference the tag number of other control stations only need to add the "Inter-station Reference Link" module to the FBD configuration program, double-click the module, and in the pop-up "Inter-station Reference Tag Number Selection" dialog box, select the control station to reference and the tag number within that control station, and click OK to complete the direct reference of the inter-station tag number. The specific referencing method is as follows:

[0054] See Figure 1 , Figure 1 A flowchart of a method for directly referencing inter-station tag numbers provided in this application embodiment includes:

[0055] S101: Determine whether the first control station where the referenced bit number is located has been detected.

[0056] In response to the user's reference operation, the referenced bit number is determined, and the first control station where the referenced bit number is located is identified. First, it is determined whether the first control station where the referenced bit number is located has been detected. If not, step S102 is executed; if yes, step S103 is executed.

[0057] S102: Error message: Adding bit reference failed.

[0058] If the first control station containing the referenced tag number is not detected, a tag number reference addition failure message will be displayed. For example, a pop-up message will appear saying "Control station xx not detected, tag number reference addition failure!".

[0059] S103: Open the first station inter-station communication program page of the first control station.

[0060] If the first control station where the referenced tag number is located has been detected, the inter-station FBD communication program page of the first control station where the referenced tag number is located will be opened in the background, i.e., the first inter-station communication program page.

[0061] S104: In the first station inter-station communication program page, check if the referenced bit number exists in the data reference block connected to the transmit pin of the first control station.

[0062] In the first station communication program page, check if there is a referenced bit number in the data reference block connected to the transmit pin of the first control station. If yes, proceed to step S105; otherwise, proceed to step S107.

[0063] S105: In the first inter-station communication program page, search from top to bottom for the first pin that matches the transmit pin type.

[0064] In the first inter-station communication program page, search from top to bottom for the first pin that matches the transmitting pin type. If a pin that matches the transmitting pin type exists, proceed to step S106. If no pin that matches the transmitting pin type exists in the first inter-station communication program page, prompt that the transmitting pin number of the first control station is full. For example, a pop-up message will appear saying "The transmitting pin number of xx control station is full and cannot be added!".

[0065] S106: Write the referenced bit number into the data reference block connected to the pin.

[0066] If a pin of the same type as the transmit pin exists, the referenced bit number is written into the data reference block connected to the first pin of the same type as the transmit pin from top to bottom in the first inter-station communication program page. Then, step S107 is executed.

[0067] S107: Control the second control station to add a tag with the same type as the referenced tag.

[0068] The second control station adds a custom bit number of the same type as the referenced bit number, such as "CUSTOM_AI001", to ensure bit number consistency.

[0069] S108: Open the second station inter-station communication program page of the second control station.

[0070] Open the inter-station FBD communication program page of the second control station in the background, i.e., the second inter-station communication program page.

[0071] S109: In the second station communication program page, find the function block pin that corresponds to the function block of the first control station and whose function block number and function block pin number are consistent.

[0072] In the second station communication program page, find the function block pin that corresponds to the function block of the first control station and that matches the function block number and function block pin number.

[0073] S110: Determine whether the function block pin is connected to the data reference block.

[0074] Determine whether the function block pin found in step S109 is connected to the data reference block. If yes, proceed to step S111; otherwise, proceed to step S112.

[0075] S111: Add a data reference block and connect it to the function block pin.

[0076] If a function block pin is not connected to a data reference block, a data reference block is added, a custom bit number is written before the bit number, and the function block pin is connected to the added data reference block to enable referencing of the referenced bit number.

[0077] S112: Indicates that the receiving address of the second control station has been occupied.

[0078] If a function block pin is connected to a data reference block, a message will appear indicating that the second control station receiving address is already in use. For example, a pop-up message will appear saying "The receiving station address is already in use and cannot be added!".

[0079] In this embodiment, it is first determined whether the first control station containing the referenced bit number has been detected. If so, the first inter-station communication program page of the first control station is opened, and the referenced bit number is checked in the data reference block connected to the transmit pin of the first control station. If so, the second control station is controlled to add a bit number of the same type as the referenced bit number. The second inter-station communication program page of the second control station is opened, and the function block pin corresponding to the function block of the first control station, with the same function block number and function block pin number, is checked. Then it is determined whether the function block pin is connected to the data reference block. If not, a data reference block is added and connected to the function block pin to reference the referenced bit number. This realizes inter-station bit number referencing and reduces the difficulty of inter-station bit number referencing.
