Background
The noun explains:
PLC: the PLC control system is a kind of Programmable Logic Controller, and is an electronic device specially designed for industrial production and operated by digital operation, and it adopts a kind of Programmable memory for storing program therein, executing Logic operation, sequential control, timing, counting and arithmetic operation, etc. and controlling various kinds of machinery or production process by digital or analog input/output.
Coupling, also called Coupling, is a measure of the degree of association between modules. The strength of the coupling depends on the complexity of the interface between the modules, the manner in which the modules are called, and how much data is transferred across the interface. The coupling degree between the modules refers to the dependency relationship between the modules, including a control relationship, a call relationship and a data transfer relationship. The more the modules are linked, the stronger their coupling and the less their independence (the lower the coupling, the better the independence). The degree of coupling and cohesion are commonly used as criteria for measuring the degree of independence of modules in software design. One criterion for partitioning the modules is high coherence low coupling.

Generally speaking, in the existing logic service coding of interaction between the PLC and the wire control program, once there is a service change or a new service addition, the wire control program needs to be recoded, which results in low stability of the wire control program in the production process and further causes instability of workshop production.

The following describes in detail a specific implementation process of the visual interaction method between the PLC and the wire control program of the present invention:
as shown in fig. 2, in the prior art, a wire control program integrates a program service code, a PLC, a wire control program communication code, and a PLC and wire control program communication interaction service code, which mainly has the disadvantage that the coupling degree of the wire control program is too high, so that if the workshop production service flow is changed or needs to be expanded, a new functional block is required to be expanded, and the function of the complex logic service code where the PLC and the wire control program interact is difficult to expand and maintain. The main risk is that the wire control program needs to be recoded once the communication interaction service of the PLC and the wire control program changes or is newly increased. This will greatly increase the instability of the by-wire program in the production process, resulting in unstable production in the plant.
As shown in FIG. 3, the present invention addresses the shortcomings of the prior art by providing a visual interaction method to solve the complex process of interacting with PLC and program logic. The invention has the main functions of modularizing logic service codes interacted between the PLC and the wire control program, the service codes of the wire control program and the communication codes of the wire control program and the PLC, so that each module is relatively independent, and the wire control program is only responsible for the service codes and can load and execute other modules only when in operation. In the invention, the coupling degree between the modules is low, the influence degree of the drive-by-wire program in later maintenance and function extension is reduced, and the stability is improved.
Specifically, the execution steps of the present embodiment are as follows:
s1, PLC and wire control program communication service coding;
in the embodiment, an independent class library is firstly created to realize each service logic for communication interaction with the PLC. The following describes the specific implementation steps of step S1 in detail by taking the communication interaction of the form-sharing system as an example:
s11, create a class library, and add 2 folders (handles, Params) in the class library.
And S12, creating the communication service class in the Handle folder, and compiling the service.
This embodiment takes the example of adding package code scanning communication interactive service. In this embodiment, a PackScanHandle class is added under a Handle directory, and the class must inherit a communication base class extensactivtybase prestored in a class library, then rewrite a method Handle of the extensactivtybase class, and implement a communication service code in the method.
S13, creating a communication parameter class in the Params folder, and writing the attribute of the communication parameter class. The communication parameter class in the Params folder is mainly provided for the communication service class in the Handle folder to transmit parameters.
In this embodiment, the package code scanning communication interaction parameter is added as an example. In this embodiment, a PackScanParam class is added under the Params directory, and the class must inherit the communication parameter base class davincipampamsase pre-stored in the class library, and then the attribute of the class is written.
S2, designing a communication interaction process;
s21, the present embodiment designs a "reference upload" function on the flow designer, and selects and uploads the class library created in step S1 by clicking the "reference upload" button.
S22, in this embodiment, a flow is created first, and then the flow is edited to configure corresponding flow nodes for the flow. Specifically, in this embodiment, after the flow is selected, the flow is selected and edited by the right key, and the flow node is dragged to the corresponding design canvas.
S23, according to the configured flow node, the embodiment configures the input/output parameter object of the flow node. Specifically, in this embodiment, the input and output parameter objects are configured in the pop-up configuration window by double-clicking the flow node.
In this embodiment, after the node configuration is opened, different nodes are added according to different node types, for example:
1) adding an (Add PLC Read) node when PLC data needs to be Read;
2) when the communication service needs to be processed, adding an (added Program explorer) node;
3) when a value needs to be written to the PLC, adding an (Add PLC Write) node;
after different nodes are added, the embodiment configures corresponding input parameter objects, output parameter objects, and business logic processing objects for the different nodes.
For example:
1) for Add PLC Read node: whether a task is created when the node is required to be configured and executed; whether each process executes the node or not is executed in sequence; whether the node has a response; and configuring the parameter class (from the class library uploaded in step S1) output after executing the node for use by the next node.
2) For the Add Program explorer node: configuring the Handle service class and method to be executed when executing the node (from the class library uploaded in step S1); and configuring the parameter class (from the class library uploaded in step S1) output after executing the node for use by the next node.
3) For Add PLC Write node: configuring the communication interaction point name of the node; and configuring the parameter class (from the class library uploaded in step S1) output after executing the node for use by the next node.
And S24, adding each node in the flow, and configuring the nodes and the associated connecting lines among the nodes.
S25, configuring the condition for executing the next node on the connection line, wherein the source of the condition is from the attribute in the output parameter object configured in the step S23.
The specific operation of this embodiment is as follows:
a) double-clicking a connecting line, and clicking an Add drop-down list in a popped configuration window;
b) if the Group button is selected, a condition Group is created;
c) and if the condition button is selected, creating a separate condition.
The specific condition content in this embodiment may be configured according to actual needs, and it is not necessary to use all attributes of the parameter class as the condition.
And S3, adding the starting code of the flow engine program in the starting entrance of the thread control program.
In this embodiment, the process engine programs in the steps S1 to S2 are finally started, so that the visual interaction between the PLC and the wire control program can be realized.
In summary, the process design steps of the visual interaction between the PLC and the wire control program of the present invention are: firstly, creating a process, designing process nodes and associating node relations, then configuring relation conditions, configuring node services, and finally storing all data of the process to obtain a process engine.
The specific flow execution steps of the visual interaction between the PLC and the wire control program are as follows: firstly, encoding PLC communication interactive logic service, then designing a communication flow, then loading a flow engine through a wire control program, and finally starting and executing the flow engine.
The invention solves the processing process of interaction between the PLC and the wire control program and complex program logic by using a visual configurational method.
In addition, compared with the prior art, the invention simplifies the maintenance and the expansion of the communication interaction between the PLC and the wire control program, once the communication interaction service needs to be adjusted or expanded, the communication interaction service can be realized only by adjusting a designer and a communication service library and then restarting the wire control program, thereby avoiding the risks of unstable programs and the like caused by the adjustment of the wire control program.
While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
