16.1.27 List Components Functionality
The text input is supported noticing standard IEC 61131-3. The 'IEC 61131-3 Text
Editor' plug-in provides a kind of "List Components" functionality, which can be
activated or deactivated in a project in the Text Editor options.
"List Components" helps to insert a correct identifier:
• If you - at any place, where a global identifier can be inserted - insert a dot "."
instead of the identifier, a selection box will appear, listing all currently available
global variables. You can choose one of these elements and press to
insert it behind the dot. You can also insert the element by a doubleclick on the list
entry.
• If you enter a function block instance or a structure variable followed by a dot, then
a selection box listing all input and output variables of the corresponding function
block resp. listing the structure components will appear, where you can choose the
desired element and enter it by pressing or by a doubleclick.
