Find unused Variables
NOTE Finding unused variables can only be performed if the project has been build and was not
changed since them. Otherwise a warning message will be displayed.
Each unused variable is listed under the container of its declaration: the Global Variable List for
global variables, or the corresponding POU for local variables. Only those containers are listed
where unused variables exist. For example, if there is no global variable, the Global Variable List
location will not be enlisted. Containers are written in bold text and appear at a higher level than
their contained items.
