The Scaling Active option must be selected to apply user defined scaling.
Values which determine when the bar is empty or full are set in the 0% Value and 100% Value fields,
respectively. These specifications are automatically converted to the set length of the bar.

4.6.4 Text and Graphics Output Using an Index
This type of output field is used for displaying dynamic status information where the value of a numeric process
variable corresponds to a text or bitmap from a predefined collection. The PLC application only needs to process
the numeric status information. Visual Components automatically takes care of displaying the correct text or
bitmap in the visualization application.
In this way, the same status information can be represented several times in the visualization application, i.e.
once as a text and again as a bitmap graphic.
The following output fields are possible:
• Advanced Text Output
• ListBox
• Bitmap Graphic
The displayed text or bitmap can be changed at any time by changing the value in the control application.
Language switching can also be used for these dynamically displayed texts.
Text or bitmap lists can no longer be influenced during runtime (except for ListBoxes which can use a process
variable for the preparation of texts. In this case, language switching has to be turned off in the PLC application).
Tip:
By combining output fields described in this section with HotSpots, active input elements can be created very
easily with bitmaps and texts!
