The Object Organizer is always located on the left side of CoDeSys. At the bottom there are four
register cards with symbols for the four types of objects POUs, Data types, Visualizations
and Resources. In order to change between the respective object types click with the mouse on
the corresponding register card or use the left or right arrow key.
You will learn in chapter Managing Objects in a Project how to work with the objects in the Object
Organizer.
