With 'Project' 'Rebuild all', unlike the incremental compilation, the project is completely recompiled⮫ “'Project' 'Build'”. Download information is not discarded, however, as is the case with the command 'Project' 'Clean all'⮫ “'Project' 'Clean all'”⮫ “'Project' 'Load download information'”. Note the possibility to exclude objects from compilation⮫ “Options for build”.

See 'Online' 'Login' for a diagram showing the relations between Project-Build, Project-Download, Online Change and Login on the target systemFigure.
