WebAPISampleApp

This is a simple Windows Forms HMI application that uses the In-Sight Web API. It includes a project to build a base assembly for accessing the Web API, Cognex.InSight.Web. It also includes a project that holds the Windows Form Controls for visualization, Cognex.InSight.Web.Controls.

Project

This Visual Studio 2022 project uses .Net 4.8.

The project may require the following NuGet package installations:

• Microsoft.Build by Microsoft 17.8.3
• WebSocketSharp.Standard by web-sharp-standard 1.0.3

Application

The MainForm in the application includes:

• Connecting to an IP address with HMI port using a designated username and password
• Menu that includes manual trigger, online/offline, information about the camera, etc
• A CvsDisplay control to display the image and graphics
• A CvsSpreadsheet control to display the spreadsheet
• A CvsCustomView control to display the custom view
• A CvsFilmstrip control to display the results queue filmstrip

Cognex.InSight.Web Project

This project provides the core classes to establish a CogSocket connection to the In-Sight camera.

Includes:

• CvsInSight.cs class and the supporting SimpleCogSocket classes
  • Added GetCellValueByLocation(string cellLocation)
  • Added GetCellValueByName(string cellName)
  • Added SendNMC(string nmc, double timeout, int port, string ipAddress, string username, string password)

Cognex.InSight.Web.Controls Project

This project provides the controls and dependencies that rely on Windows Forms.

Includes:

• CvsDisplay.cs UserControl that uses PictureBox to display the image from the results and overwrites graphics
• CvsSpreadsheet.cs UserControl that uses a DataGridView to display a spreadsheet for the cell results
• CvsCustomView.cs UserControl that uses the CvsSpreadsheet to display a custom view
• CvsFilmstrip.cs UserControl to display the results queue filmstrip

Support for Dialogs, Wizards, and Bitmaps

Because the new In-Sight sensors (2800/3800 and beyond) do not support the Wizard and Dialog cells, support for HMI defined cells is added. The "Jobs" directory includes a sample job, ExampleHmiSpreadsheetCells.jobx, and json file, ExampleHmiSpreadsheetCells.json. This json file contains definitions for cells that will overwrite or replace any cells from the sensor when they are displayed in the sample application. This json file may be loaded in the sample application after the correct job has been loaded in the sensor.

The following cell types are supported:

• DialogCell - Display a "Dialog" button at the designated location. This button will display the designated dialog. Example: { "$type": "DialogCell", "location": "A3", "label": "Dialog1", "title": "Dialog 1", "range": "A400:E405" }

• WizardCell - Display a "Wizard" button at the designated location. This button will cycle through the designated dialogs. Example: { "$type": "WizardCell", "location": "A2", "label": "MyWizard", "dialogs": [ "A3", "A4" ] }

• BitmapCell = Display the designated bitmap in the cell. The image will be loaded from the same directory as the json file. Example: { "$type": "BitmapCell", "location": "A1", "file": "Nyan_cat_125px_frame.png" }
