Creating POUs
A POU (Program Organization Unit) is a subdivision from the applicative program, which can be
written in any language available in the software.
With the project creation through a selected profile, some POUs are already created. It is possible to
create more POUs, up to the maximum limit of the program memory size.
To insert a new POU, click on Application (default name created for the application), select “Add
Object” and, finally, “POU...” (Figure 5-10):
Figure 5-10. Inserting POUs
A configuration window will pop up on the screen. Name the POU and select the type/language to be
implemented. Click “Add”.
