The View > All Variables command opens the All Variables view. This separate view window provides an overview of the variables declared in the project.
Each variable is listed in a separate line with columns for the usual definitions for variable declaration: Scope, Name, Address, Data type, Initialization, Comment and (pragma) Attributes as described in the Tabular Declaration Editor chapter.
In addition to these standard definitions, the All Variables view contains the column Parent. This column lists the object in which the variable is declared, that is the name of the POU or GVL.
You can double-click a variable to open the editor of the parent, that is the element in which the variable is declared.
In order to display variables of I/O modules, activate the option IO Mapped Variables.
