Info

Now you will add the function which copies the index of the current selection to an additional variable when a key is pressed. First you will need a touch button whose Key Type under the Action tab is set to "Momentary USINT". In the Data Point area, select the variable 'LBButtonDown' using the Assign... button and enter the number 1 as Value 1. This button function means that the 'LBButtonDown' variable keeps the value 1 as long as the button is pressed down on the screen. If the button is released, then the variable is set back to the value 0. Under the Appearance tab, choose 'Enter' from the Text combo box. Confirm the input by clicking OK. Next to the new 'Enter' button, add a numeric input field which is connected to the 'LBSelldx' variable. The value of the currently selected entry is stored in this variable after the 'Enter' button is pressed. The finished picture is shown in the following image: Introduction to Visual Components 2.3 260 4.2.2.11 IPC − Step 11: Page 3 − Inserting a ListBox with Control Buttons
Introduction to Visual Components 2.3 The Automation Basic task 'dummy' has to be expanded a bit for the 'Enter' button to function properly. The variables are now executed in the Init−SP part of the task. The Init−SP part can be shown if you move the 'splitter' on the upper border of the source code window to the middle (see image). The IF condition is true so long as the 'Enter' button is pressed. Then the contents of the LBCurldx variable (which contains the current index of the ListBox) are copied to the LBSelldx variable which is displayed in a separate output field in this example. In a real application, this type of function could be used for loading or saving a recipe. This ends the configuration process of the example project. The next step concerns compiling and transferring the project to Automation Runtime. 4.2.2.12 IPC − Step 12: Compiling and Transferring the Project Save the changes to the project and close the panel object. Now you are ready to compile the project and transfer it to the controller. Click on the icon in the toolbar to compile the project. This doesn't just affect the panel object; all components in the project that have been changed or added are compiled. Compilation progress is displayed. 4.2.2.12 IPC − Step 12: Compiling and Transferring the Project 261
