When you create a project, a Program Organization Unit (POU) with the name “Main” is cre-
ated automatically for standard controllers in the “COMPONENTS” area under “Programs”
(see Figure 4-24 on page 107).
Opening the POU To open a POU, proceed as follows:
• Click on “Programming (x)” in the “COMPONENTS” area.
• Then click in turn on the arrow next to “Local (x)” and “Programs (x)”.
• Double-click on the desired POU (in the example: “Main” program).
The editor group for the selected POU opens. You are prompted to select the programming
language for the first worksheet of the POU.
