Description

Technical Field

[0001] The invention relates to a PIO configuration system and to the technical field of industrial control system applications. Background Art

[0002] As the degree of industrial automation increases, the application scenarios of industrial control systems such as DCS are increasing. The on-site PIO signals are connected to the PIO hardware module, and the PIO module collects and converts the on-site signals before uploading and sending them down. The configuration steps for engineers are to first configure and collect the PIO signals entering the IO module, and then convert the collected physical signals into engineering quantities that can be used in the logical configuration. Engineers need to perform two-step conversions before they can use the PIO signals in the logical configuration. The configuration process is cumbersome. At the same time, due to the increasing number of on-site PIO signals, the conversion types are numerous and complex, and the amount of conversion configurations also increases. On the other hand, the PIO module status and PIO channel status are generally viewed in the device status interface and channel point interface respectively. During debugging and maintenance, it is necessary to switch back and forth and query, which increases the difficulty of configuration and debugging maintenance. Summary of the invention

[0003] The purpose of the present invention is to design a PIO configuration system in order to solve the above-mentioned problems of large configuration volume, great difficulty and low efficiency.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions, a PIO configuration system, including: S100: The system develops and designs a PIO module macro for each PIO module. The PIO module macro has a standard parameter table, including macro code, input and output addresses, and macro parameters. The macro parameters include PIO module information and each PIO channel information. The PIO module information includes module status information and module operation type. Each PIO channel information includes detailed information such as the control mode, recording mode, alarm level, alarm dead zone, channel signal name, range, coordinates, etc. of the channel. The system designs a standard PIO logic page for each PIO module. The standard PIO logic page includes PIO module macro, module control cycle, channel quality information, hardware fault information, and network communication interface status. The system designs a PIO channel macro. When the user performs control logic configuration, the PIO channel macro can be used to configure the PIO signal.

[0005] S101: The system is designed with a module PIO module configuration module. The user selects each PIO module by pulling down the PIO module menu in the controller configuration interface.

[0006] S102: The system is designed with an automatic logic diagram generation module. After the user configures the PIO module, the system automatically generates a PIO logic diagram instance of the configured PIO module based on the standard PIO logic diagram of each PIO module.

[0007] S103: The user selects a PIO module macro in the automatically generated PIO logic page, then selects a PIO channel, and modifies channel parameters in the PIO channel property interface.

[0008] S104: The system compiles and generates a macro parameter table according to the PIO module and channel parameter configuration information.

[0009] S105: When the user is configuring the control logic, the user directly uses the PIO channel macro and configures the module type, channel number, and PIO logic diagram page number of the PIO channel macro in the macro property interface of the PIO channel macro.

[0010] Furthermore, to facilitate user configuration, for multiple channels with the same channel attributes in the same PIO module, users can select multiple channels at the same time and make unified settings in the drop-down menu to complete the batch configuration, thereby improving user configuration efficiency.

[0011] Furthermore, in order to simplify the user configuration steps, after the user configures the PIO module, the system automatically generates a PIO module measurement point table. The user can modify the PIO measurement point information on the generated measurement point table, including channel type, channel quality, physical range, engineering range, alarm type, alarm dead zone, alarm high and low limits, IO channel corresponding signal name, signal type, and after the modification is completed, use the measurement point import function to import it into the logic diagram.

[0012] Furthermore, when all PIO configurations are completed, the system compiles and automatically generates the parameter files used by the controller, and also automatically generates the database import files required for the operator station configuration, thereby improving the efficiency of the operator station configuration.

[0013] The beneficial effects of the present invention are as follows: the PIO configuration system is simple and clear in function, and can be called conveniently and quickly during user configuration. It can automatically generate a standard PIO logic diagram, which can be used directly by the user. At the same time, the user can modify various information of the signal through a drop-down menu, thereby simplifying the multi-step configuration work of the PIO signal. At the same time, the system provides a PIO measurement point import function, which can be conveniently and quickly edited in a table and then imported into the system. The system compiles and automatically generates a page parameter table, which greatly reduces the configuration time. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] S101: The system designs a PIO module configuration module, such as Figure 5 As shown, the user selects the PIO module from the drop-down menu in the controller configuration interface to configure the PIO module used by the system.

[0025] S102: After configuring the PIO module, Figure 6 As shown, the system automatically generates a PIO logic page instance and automatically generates a PIO logic page number 63 according to the controller station number and node number of the module. In the PIO logic page, by selecting a single PIO channel 61 of the PIO module macro instance 60, the channel attribute parameters can be modified in the macro attribute interface 62.

[0026] S104: The system compiles and generates a macro parameter table according to the PIO module and channel parameter configuration information.

[0027] S105: Figure 7 As shown, when configuring the control logic, the user uses the PIO channel macro instance 70 to set the module type, channel number, and the PIO logic diagram page number where the channel is located in the PIO channel macro property interface.

[0028] As an optimization technical solution of the present invention, in order to facilitate user configuration, for the same channel properties of different channel measurement points in the same PIO module, the user can select multiple channels and set them uniformly in the macro property interface, so as to complete the batch setting quickly and efficiently.

[0029] As an optimized technical solution of the present invention, after the user configures the PIO module, the system automatically generates a PIO module measurement point table.
