Result
The blocks of the basic SINUMERIK PLC program have been copied to your project. Any
copied folder structure (Page 82) has been imported.
Figure 4-3
Now you can check the copied blocks and, if applicable, manually delete the PLC basic
program blocks that you do not require (e.g. unused axis DB, channel DB, FB or FC).
If you have unused blocks in your project, some tasks take unnecessarily long, e.g. the loading
or the creation and import of SINUMERIK archives.
