Using Visualization Elements to Control Recipe Management dl-permalink__symbolPermalink

You can manage and use the recipes created in CODESYS by means of a visualization.

For this purpose, the input configuration of a visualization element provides the capability of using the “Execute Command” input action to execute the following commands:

  • “Read Recipe”

  • “Write Recipe”

  • “Load Recipe from File”

  • “Save Recipe in File”

  • “Create Recipe”

  • “Delete Recipe”

For more information, see: ⮫ Dialog:Input Configuration

Example: Loading recipes by means of visualization elements

Requirement: The “Visualization” object is added to the project.

  1. Create a recipe according to the instructions in the "Changing Values with Recipes – Creating Recipes" chapter.

    Assign the following names:

    • Recipe definition: "Recipes"

    • Recipes: "Recipe1" and "Recipe2"

    • Variables: ‎iValue1‎ and ‎iValue2‎

    Type in different variable values of both recipes.

  2. Open the “Visualization” object in the editor.

  3. Drag a “Button” element to the visualization. Label it "Load Recipe 1". You can specify the text by double-clicking the element or in the “Texts  Text” property.

  4. Click the value field of the “Input configuration”: “OnMouseDown” property.

    The “Input Configuration” dialog opens.

  5. Select “Execute command” in the left of the left side and click the _visu_img_input_configuration_button.png button.

    The configuration of the “Internal command” opens on the right side of the dialog.

  6. Select the “Write Recipe” command from the list box.

  7. Click the _visu_img_input_configuration_button_plus.png button.

    The “WriteRecipe” command is added to the list.

  8. Specify the first parameter as ‎Recipes‎ and the second parameter as ‎Recipe1‎.

  9. Click “OK” to exit the dialog.

  10. Drag a second button to the visualization, name it "Load Recipe 2", and repeat steps 4 to 8. For Step 7, specify ‎Recipe2‎ as the second parameter.

  11. Load the program to the controller and start it. Click the “Load Recipe 1” and “Load Recipe 2”, and monitor the variables ‎iValue1‎ and ‎iValue2‎.

The other recipe commands are assigned to visualization elements in the same way as this example. For a description of the internal commands, see the ⮫ help page of the input configuration.
