In the left part of the editor window the currently Available variables of the
application are shown in a tree structured by a "Variables" and a "DataTypes" node.
Indented each below these nodes find the POU, GVL
and data type names and again
below finally the names, data types and access right of the particular variables (items).
Via the Refresh button the tree can be updated with the currently valid variables. With
the compiler option Link Always a not compiled object can be reinterpreted and
downloaded to the PLC. Then all variables declared in this object will be available. In
addition the pragma {attribute 'linkalways') can be used to make not compiled
variables available in the symbol configuration.
In the right part of the window the currently Selected variables are displayed also in a
tree structure. For those items each a symbol definition will be created and exported to
the symbol file. The Display invalid variables button will indicate by a red writing all
variables which are currently not valid in the application, for example because their
declaration has been removed.
Use the single-arrow buttons in the center of the editor window to add a currently
selected item (or node) from the left tree to the right tree resp. to remove one from
there. The double-arrow buttons always will take the complete list, in this case
nothing must be selected explicitly .
The access right for a selected item can be modified in the right window by a mouse-
click on the symbol in the Access Rights column. Each mouse-click will switch the
symbol within the following definitions: read+write, write-only, read-only.
The checkbox Show libraries in "Available variables" defines if variables of libraries are
also displayed.
The Instance Path of a currently selected item is displayed in the same-named field in
the bottom part of the dialog. It can be copied to the clipboard by the Copy Instance
Path button, which might be useful for inserting a long path to any text edit field.
If the symbol configuration has been modified in online mode, the modified
application can be downloaded via button Download.
