Hello mnplc

first of all

Dynamic entries in Textlists are not possible in WinCC Professional!

But you can use insted of textslists and symbolic IO Field a combobox Control.

Here you can run a Script (for example at screen loading event) to fill the Combobox with entries you need, or also dynamically if you need so.

Here a little example (of course with dummy object names...)

------------------

Dim ComboObj

Set ComboObj = ScreenItems("NameOfComboboxControl")

ComboObj.NumberLines = 3

ComboObj.Index = 1
ComboObj.Text = "Text 1"
ComboObjj.Index = 2
ComboObj.Text = "Text 2"
ComboObj.Index = 3
ComboObj.Text = "Text 3"
