TECHNICAL FIELD

[0001] The present application belongs to the technical field of industrial automation control, and particularly relates to a PLC configuration data automatic generation technology. BACKGROUND

[0002] In the traditional development process, engineers need to perform repeated configuration in the PLC programming environment (such as STEP7) and configuration software (such as WinCC) respectively, which is tedious and increases labor intensity, and there is consistency risk: manual operation is easy to cause the mismatch between the PLC program variables and the configuration elements, the configuration configuration consumes more than 30% of the total project time, and reduces the development efficiency of the PLC. SUMMARY

[0003] A PLC configuration data automatic generation method, comprising:

[0004] (a) defining a configuration tag set for each programming object in the attribute configuration interface of the PLC programming software, the tag set at least containing a graphical icon associated tag;

[0005] (b) in response to the modification of the graphical icon associated tag, writing the changed content into an independent configuration data file in real time;

[0006] (c) when the PLC program is compiled, parsing the configuration data file to generate a configuration picture description file.

[0007] The configuration tag set further contains a text content tag for defining object description text; the modification of the text content tag is synchronized to the configuration data file in real time.

[0008] The configuration tag set further contains an operation permission tag for configuring visibility and operation rules; the modification of the operation permission tag is synchronized to the configuration data file in real time.

[0009] Icon binding engine: persistently storing the graphical icon associated tag to the object attribute data structure; permission executor: when there is an operation permission tag, dynamically controlling the operation permission of the configuration picture. BRIEF DESCRIPTION OF DRAWINGS

[0016] Embodiment 1

[0017] Open the water pump object Y0 in the PLC programming software, enter the configuration label set configuration interface, and configure the graphical icon associated label: select the "water pump" icon from the standard icon library, and upload the custom icon file "emergency water pump.png", and the content description is "water pump"; perform the same operation on the valve object Y1, bind the standard "valve" icon, save the modification, and the system automatically generates the "water system.scada" configuration data file; when the PLC program compilation is completed, the system parses the file and automatically generates the configuration picture: the water pump position displays the blue water pump icon, and the valve position displays the standard valve icon.

[0018] Embodiment 2

[0019] First, configure the motor object M1: select the "three-phase motor" standard icon, and edit the text content label: display name: "main drive motor", and note: "drive packaging line conveyor belt"; configure the sensor X0: select the "photoelectric sensor" icon, and input the text content: "packaging in-place detection". All modifications are synchronized to the "packline.scada" file in real time, and the generated configuration picture after compilation: the "main drive motor" text description is displayed below the motor icon, and the sensor position displays the corresponding icon and text.

[0020] Embodiment 3

[0021] The icon and permission label definition are configured in the valve object attribute interface, the graphical icon associated label, the normal state "green valve icon", the alarm state "red flashing valve icon", and the content description is "valve".

[0022] The authority performs verification, the engineer logs in the configuration picture, and can click the valve icon to operate; the operator logs in, only shows the gray icon, the chlorine concentration exceeds the standard, all roles are locked, and the icon flashes red.
