27.6.1 Sample Projects and Sample Programs
The STEP 7 installation medium contains a number of useful sample projects that are listed
below. You will find the sample projects in the "open" dialog of the SIMATIC Manager ("Sample
Projects" tab). Other sample projects may also be added when optional packages are installed. For
information on these sample projects, refer to the documentation for the optional packages.

The emphasis of the examples is not on teaching a particular programming style or the specialist
knowledge needed to control a particular process. The examples are simply intended to illustrate
the steps that must be followed to design a program.
