Today, I would like to share with you how SuperIO derives data-driven knowledge points. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

1.1 the role of the export data interface

In the data integration system project, either they integrate the equipment of other manufacturers, or other manufacturers integrate their own equipment, in the absence of a unified standard, there will be a variety of integrated data formats. In order to meet such scenarios, an API is specially designed for the device to output data. Developers can inherit the interface. After processing the data, the device will automatically transfer the data to the interface and output the data in the specified data format.

1.2 functional description of the interface

The development of the device output interface mainly takes into account the output of various data formats in the integration project, during the integration process or during the integration process. You need to inherit the SuperIO.Export.IExportData API, which includes:

1) ThisKey

Returns the form ID, and it is unique. If the same form exists, it will not be displayed again.

2) ThisName

Form name.

3) UpdateDevice

Update the device data to receive the object instance passed in by the device OnDeviceObjectChangedHandler event.

4) RemoveDevice

Remove the device, and this function interface is called when the device is deleted.

5) Dispose

Release the resource function.

6) FormatDataString

Data formatting interface function. You don't have to use it.

1.3 Development and export data driver

1) add references to SuperIO components.

2) create a new class, inherit the SuperIO.Export.IExportData interface, and implement the interface function.

3) parse the object through the UpdateDevice interface and output the formatted data.

1.4 debugging export data driver

Interface mode testing has a form interface, which must inherit the "SuperIO.UI .mainform" class.

And set the software platform to debug mode "SuperIO.Device.DebugDevice.IsDebug = true;" with code, as shown in the figure:

Initialize the instance in Form_Load, and load the debug graphics display module, mainly to create an instance, such as: this.DebugExportData ((SuperIO.Export.IExportData) _ export) statement. As shown below:

1.5 Mount and export data driver

In the "industrial serial port and network software communication platform _ SuperIO" directory, find the [ConfigTool.exe] application, select the "Export data configuration" tab, click the "Mount Export" button, and mount the export data driver module just developed to the platform. As shown below:

1.6 run under the software platform

When the platform software starts, it will check whether the exported data instance is mounted in the configuration file. If there is an exported data instance, it will automatically load the instance and run under the platform. Information about the exported data instance is not displayed in the interface. After adding or deleting exported data instances through the configuration tool, you should restart the platform software.
