Displaying Variable Values in the Visualization¶

There are visualization elements ranging from simple to very specialized for displaying the data of a running application.

Some examples:

Simple output of variable values: For an element Rectangle, for example, you configure a pure formatting specification in the property Text and the variable whose value is to be displayed in the element in the property Text variable.
Displaying structured variable values (structure, array, function block): You use the element Table and in its configuration in the property Data array you enter an array variable whose values are to be displayed in the table. One-dimensional arrays can also be visualized in a histogram.
Displaying values by image toggling. Example: a certain plant image is shown depending on the error message that occurs. To this end you configure an element Image with a variable in the Image ID variableproperty.
Displaying a variable value as a bar or with a pointer on a scale: enter a variable in the property Value of the element Bar display or element Meter in order to display its value as a bar on a horizontal or round scale.
Displaying alarms: The alarms configured in the alarm management of the application can be made visible in the user interface via the elements Alarm table and Alarm banner.
Trace and Trend: for the graphic recording of variable values over a period of time.

See the descriptions of the respective element properties for details.
