One skilled in the art, under the guidance of this application, may add one or more other operations to, or remove one or more operations from, the flowchart.
In addition, the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application.

It should be noted that in the embodiments of the present application, the term "comprising" is used to indicate the presence of the features stated hereinafter, but does not exclude the addition of further features.
In the software interface of the PC terminal provided at present, the same configuration page is used for configuration of a digital quantity input, a digital quantity output, an input register and a holding register. However, the configuration modes required by the four information types during configuration may be different, and therefore, when a same page is used for configuring a plurality of information types requiring different requirements, the configuration process of a user becomes cumbersome, and configuration efficiency is low.
In addition, for the input register and the holding register, in actual use, the mapping of PLC byte data to the PC-side communication variables may need to be performed, so that when other devices use the data of the input register or the holding register, the other devices can use the data based on the PC-side communication variables. However, in the current PC-side software, a configuration function for mapping PLC byte data to PC-side communication variables is not provided, which results in a low user experience.
Based on the above problems, the embodiments of the present application provide a PLC data processing method, which provides independent configuration interfaces for digital input, digital output, an input register, and a holding register, and provides a mapping configuration from PLC byte data of the input register and the holding register to a PC-side communication variable, so that a user can conveniently configure PLC data, and user experience is greatly improved.

Specifically, the PC may also be connected to other electronic devices, or some processing software may be installed on the PC. After the PC reads the point location data from the PLC, the other electronic devices or processing software may read the point location data from the PC for subsequent processing, and/or the other electronic devices or processing software may set the point location data of the PLC and write the point location data into the PLC via the PC. The other electronic devices or the processing software request the PC to read point location data of the PLC or instruct the PC to write the point location data into the PLC by using a variable name configured at the PC end as an identifier of the point location, and after receiving the read request or the write instruction, the PC can learn, based on configuration information input by a user on a configuration interface of the PC, the point location that the electronic devices or the processing software need to read or write, and correspondingly read or write the data of the point location.
The following embodiments of the present application will describe in detail a process in which a user inputs configuration information based on a configuration interface of a PC, and a process in which the PC reads point location data from and writes point location data to the PLC based on the configuration information.
Before describing the technical solutions of the embodiments of the present application, technical terms related to the embodiments of the present application are explained first.

In the following embodiments, the references to "addresses" each refer to an address to which a point bit corresponds.
2. Digital quantity input and digital quantity output
Digital quantities refer to discrete signals that vary intermittently in both time and value. In the PLC, the digital quantity input and the digital quantity output may include input and output of a switching quantity (high and low levels). For example: button digital input, coil digital output and the like. The PC can read the digital input dot data and write the digital output dot data.
3. Input register and holding register
An input register in the PLC may store the state of each input interface. The holding register may be a register that can be read or written by a communication command, typically some function control register or holding register or the like.

It should be understood that the point location data described herein refers to the numerical values at the point locations.
First, a process in which a user inputs configuration information via a configuration interface of a PC will be described below.
Fig. 2 is a schematic flowchart of a data processing method of a programmable logic controller according to an embodiment of the present application, where an execution subject of the method is the PC. As shown in fig. 2, the method includes:
s201, displaying a configuration interface, wherein the configuration interface is used for carrying out data configuration of the programmable logic controller, and the configuration interface comprises: a digital quantity input tab, a digital quantity output tab, an input register tab, and a hold register tab.
Fig. 3 is a first interface schematic diagram of the embodiment of the present application, and as shown in fig. 3, a PC may display a configuration interface. In the configuration interface, four tabs of a digital quantity input tab, a digital quantity output tab, an input register tab and a holding register tab are displayed. The left-most digital quantity input tab is selected by default, and a user can click any other tab to switch.
S202, responding to the operation that a user clicks a target tab, and displaying a configuration item of the target tab on the configuration interface, wherein the target tab is any one of the numeric value input tab, the numeric value output tab, the input register tab and the holding register tab.
As described above, when the PC displays the configuration page, the leftmost digit quantity input tab is selected by default, that is, the customer is considered to have selected the digit quantity input tab by default, and in response to this default selection operation, with continued reference to fig. 3, the PC displays configuration items of the digit quantity input tab on the configuration interface, including: digital quantity input point location, address sequence number, variable name, variable value, point location value and description. The numerical value input point bit represents an address corresponding to the point location, the address serial number represents a number of the address corresponding to the numerical value input point location at the PC end, the variable name represents a variable name corresponding to the numerical value input point location at the PC end, that is, a name used by the electronic device or the processing software communicating with the PC, the variable value represents a value corresponding to the value of the numerical value input point location at the PC end, and the point location represents a value on the numerical value input point location in the PLC.
And after the user clicks other tabs, the PC correspondingly displays the configuration items of the other tabs.
S203, responding to the operation information of the user on the configuration item of the target tab, and generating and storing the configuration information corresponding to the target tab.
Optionally, the user may perform an add, modify, or delete operation on the configuration item to implement adding, modifying, or deleting the configuration information. The specific process will be described in detail in the following examples.
When the target page tag is a digital quantity input page tag, the configuration information corresponding to the target page tag is the configuration information of one or more digital quantity input point locations, when the target page tag is digital quantity output, the configuration information corresponding to the target page tag is the configuration information of one or more digital quantity output point locations, when the target page tag is an input register, the configuration information corresponding to the target page tag is the configuration information of one or more input registers, and when the target page tag is a holding register, the configuration information corresponding to the target page tag is the configuration information of one or more holding registers.
Continuing with fig. 3 as an example, after the user clicks the digital quantity input tab, the configuration item of the digital quantity input is displayed on the interface, and at the same time, the configuration information that the user has added is displayed under the configuration item. A row represents the configuration information of a digital quantity input point location, and a user can modify the added configuration information by modifying the value of a certain configuration item, or select a certain row to delete the configuration information corresponding to the row, or input the data of each configuration item in a new empty row to add the configuration information of a new digital quantity input point location.
After the user performs the operation and confirms, the PC may store the configuration information after the user operation in a local PLC communication file of the PC, and use the file in subsequent reading or writing of point location data.
In this embodiment, the PC sets different tabs for the digital quantity input, the digital quantity output, the input register, and the holding register on the configuration interface, and after a user clicks a tab, a configuration item specific to the tab is displayed, so that the user can configure the configuration information by operating the configuration item. Through the mode, the point positions of different types are independently configured, the configuration efficiency is improved, and the use experience of a user is further improved.
When the target tab is an input register tab or a holding register tab, the user may add configuration information of several input registers or configuration information of holding registers by performing step S203. On this basis, the user can configure the mapping data for these newly added input registers or holding registers. The following description will be specifically made.
Optionally, the method further includes:
responding to the selection operation of the user for the configured register under the target tab, displaying a mapping interface, and displaying the mapping configuration item of the configured register on the mapping interface, wherein the mapping configuration item at least comprises: a variable upper limit value, a variable lower limit value, a device upper limit value, a device lower limit value, and a variable name. And responding to the operation information of the mapping configuration item by the user, and generating and storing the mapping data corresponding to the configured register.
The above process is described below by taking the configuration interface of the input register as an example, and the configuration interface of the holding register may be the same as the configuration interface of the input register, which is not described separately.
Fig. 4 is a schematic view of an interface according to an embodiment of the present application, where as shown in fig. 4, after a user clicks a tab of an input register, a configuration item of the input register is displayed on the interface, and configuration information that has been added by the user is displayed, where the configuration item includes: configuration information of the input register AI0.0 and configuration information of the input register AI 0.1. Where AI0.0 and AI0.1 respectively represent the addresses of the input registers. Input registers AI0.0 and AI0.1 are configured registers. After the user selects one of the configured registers (for example, the selection input register AI0.0 in fig. 4), a mapping interface shown in fig. 5 and described below may pop up above the interface of fig. 4. Alternatively, the user may select the configuration register by double-clicking, single-click and determining, and the like.
Fig. 5 is a third interface schematic diagram of the embodiment of the present application, and as shown in fig. 5, a mapping configuration item of a configured register is displayed in a mapping interface, where the mapping configuration item includes: a variable upper limit value, a variable lower limit value, a device upper limit value, a device lower limit value, and a variable name. The upper limit value and the lower limit value of the variable form a variable value range of the PC end, and the upper limit value and the lower limit value of the equipment form a point value range of the PLC. The variable name defaults to the variable name of the input register when the user selects the input register, which the user can modify in fig. 5. The user can add a new empty line under the mapping interface and input the data of each configuration item in the line, and after the user fills and determines the data of the configuration items, the PC generates and stores the mapping data corresponding to the input register AI 0.0. After the PC reads the point location data of the input register AI0.0 from the PLC, the variable value on the PC can be obtained according to the mapping data and used by other electronic equipment or processing software. When the PC needs to write point location data into the input register AI0.0, a point location value on the PLC can be obtained according to the mapping data and written into the PLC.
In addition, for the interface illustrated in fig. 5, the user may also modify the added mapping data by modifying the value of a certain configuration item, or may also select a certain row to delete the mapping data corresponding to the row.
In this embodiment, a mapping interface is provided for the input register or the holding register, a user can fill information of each mapping configuration item in the mapping interface, and the PC can further generate and store mapping data corresponding to the register according to the input of the user, and enable the user to perform subsequent reading and writing of register data, thereby implementing configuration of mapping from PLC byte data to a communication variable at the PC end, and greatly improving user experience.
The specific execution of steps S202 and S203 will be described below.

Accordingly, when the above step S203 is executed, the configuration information of the digital quantity input or the digital quantity output is generated in response to the operation of inputting the configuration address and the variable name by the user.
The above process is described below by taking the configuration interface of the digital quantity input as an example, and the configuration interface of the digital quantity output may be the same as the configuration interface of the input register, and is not described separately.

Furthermore, the user can input and confirm the data of each configuration item in the new empty row under the configuration item, that is, the configuration information of a digital quantity input point position can be newly added.
In addition, as illustrated in fig. 3, the PC may also display the added configuration information on the configuration interface, where a row represents the configuration information of one digital quantity input point location, and the user may also modify the added configuration information by modifying the value of a certain configuration item, or may select a certain row to delete the configuration information corresponding to the row, or may also input the data of each configuration item in a new empty row to add the configuration information of a new digital quantity input point location.
