connection if the bit index is defined literally (and not by a defined constant).
The variables provided by the chosen data source are displayed in the Provider Data
Items field. The Refresh button at top of this field can be used to update the list of
items. The variables will only be added to the list if code has been created before for
the related application!
If option Structured view is activated, the items will be listed in a tree structure,
otherwise in a "flat" list. Below node 'Application' you find the POUs used by the data
source application and their variables. If function blocks and data types are
instanciated, those and their member variables will be displayed below node
'Datatypes'. Attention: if non-structured display is active, the datatypes will not be
listed!
If option Show documentation is activated, in the Documentation field a description
