In the dynamic element Combo/Listbox, you can link certain values of process variables with texts and select them during Runtime. If the varialbe reaches the defined value, the linked text is displayed. If the text is selected in the Runtime, the value of the variable is set to the value that is linked to this text.

The following variable types are supported: Binar, analog, string

The Combo Listbox Element supports the same additional functionality as the numerical value element (lock, status, visibility, dynamic colors)

info Info

For dynamic colors:
The background color is only accepted for existing entries. The part of the element that is not filled with entries has the standard background color.

Not supported are dynamic behavior and the linking of macros to element-events (e.g. LeftClickUpÂ…)
