You have access to all the processing functions via STEP 7 objects:
And you can print and
archive objects!
You can edit and
save objects!
You can cut, copy, and
paste objects!
You can rename and
delete objects!
You can create and
open objects!
With STEP 7, you can structure a system into projects. A project contains the
entire database for an automation solution. Creating a project or a project
structure is therefore an essential prerequisite for working with STEP 7.
Figure 4-2 shows you how a project is structured:
