If all cross references within the project should be listed: Type in the identifier string
manually or copy it via copy&paste from any editor window to the Name field and
then confirm with <Enter> or use button .
If only the cross references within the same POU should be listed: Either select the
identifier string within the editor window of that POU and draw it with the mouse into
the Cross Reference List view, or activate option Automatically list selection in cross
reference view and place the cursor within the string in the editor window resp. select
that string. In this case the string will be automatically entered in the Name field and
also the list of references will be displayed automatically.
If a valid identifier has been entered, the found locations will be listed in the form of a
table showing the following information on the variable:
POU Name of the POU where the variable is used.
Variable Variable name resp. POU name of the reference.
Access How the variable is used resp. accessed at this location: Declaration / Read / Write / Call
Type Data type
Scope Scope of the variable: Global / Local
Address IEC address if defined
Location Position of the variable reference within the editor (for example line, network)
Comment Comment attached at the declaration of the variable.
The list can be sorted alphabetically along one of the columns. By a mouse-click on the
column title field the sorting will be done in ascending or descending order (toggles
with each further mouse-click).
A double-click in a line of the cross reference list the opens the corresponding POU and
the respective location of the variable will be highlighted there. This corresponds to
using button ("Show location") when a list entry is selected.
Button ("Show previous location", Shortcut: <Shift> + <F4>), will jump to the
previous entry in the cross reference list.
Button ("Show next location", Shortcut: <F4>) will jump to the next entry in the
cross reference list.
Button ("Go to definition", Shortcut: <F2>) will jump to the location, where the
respective variable is declared. The corresponding declaration editor will be opened
and the variable will be highlighted there.
Button corresponds to command Browse cross references and will effect that the
current references list is generated to the message window. This might be useful if you
want to keep the list available although the automatic display is activated and thus
the list in the cross references view might change.
