How to Change Variable Values via the Visualization

 

In addition to displaying values from the controller, a user interface is also used to enter and change values.

In general, you can configure user input for each element in its Input­configuration properties. Moreover, elements have been developed especially for specific input.

Examples:

• A Button element (or Rectangle element, and son on) that is clicked to open a predefined dialog visualization for easily speci­fying a value.

• A Slider element for changing the value of a variable by moving visual element parts, for example with the mouse. In the case of the slider: The element adjusts the value of a variable, depending on the position of the slider within the slider. You define the value range of the slider bar by means of the scale start and scale end.

• A switch element (example; Power switch) for setting a Boolean value.

• A SpinControl element for incrementing or decrementing the value of a variable in defined intervals.

• A Button element for writing a recipe, executing a specific ST code, writing a specific variable, and so on (definition in the input config­uration).
