POUs, data types, visualizations and the resources global variables, the variable configuration, the Sampling Trace, the PLC Configuration, the Task Configuration, and the Watch and Receipt Manager are all defined as "objects". The folders inserted for structuring the project are partially involved. All objects of a project are in the Object Organizer.

If you hold the mouse pointer for a short time on a POU in the Object Organizer, then the type of the POU (Program, Function or Function block) is shown in a Tooltip. For the global variables the tooltip shows the keyword (VAR_GLOBAL, VAR_CONFIG).

With drag & drop you can shift objects (and also folders, see 'Folder') within an object type. For this, select the object and shift it to the desired spot by holding down the left mouse button. If the shift results in a name collision, the newly introduced element will be uniquely identified by an appended, serial number (e.g. "Object_1").
