How is a project structured?

A Project is put into a file named after the project. The first POU (Program Organization Unit) (Program Organization Unit) created in a new project will automatically be named PLC_PRG. The process begins here (in compliance with the main function in a C program), and other POUs can be accessed from the same point ( Programs, Function Blocks and Functions).

Once you have defined a Task Configuration, it is no longer necessary to create a program named PLC_PRG. You will find more about this in the Task Configuration chapter.

There are different kinds of objects in a project: POUs, data types, display elements (visualizations) and resources.

The Object Organizer contains a list of all the objects in your project.
