Libraries
With the TIA Portal you can create independent libraries from different project
elements that can be easily reused.
Using libraries offers the following advantages:
Simple storage for the data configured in the TIA Portal:
Cross-project exchange
Central update function of library elements
Versioning of library elements
Fewer error sources when using control blocks through system-supported
consideration of dependencies
Note Other recommendations of how the user program can be optimized can be found
in programming guideline S7-1200/S7-1500.

Note Once hardware and software have been fully migrated, optimized and loaded, a
test of all functions should be carried out!
