 (1) "Project library"

– Integrated in the project and managed with the project

– Allows the reusability within the project

 (2) "Global library"

– Independent library

– Use within several projects possible

A library includes two different types of storage of library elements:

 (3) "Master copies"

– Copy of configuration elements in the library (e.g. blocks, hardware, PLC

tag tables, etc.)

– Copies are not connected with the elements in the project.

– Master copies can also be made up several configuration elements.

 (4) "Types"

– Types are connected with your usage locations in the project. When types

are changed, the usage locations in the project can be updated

automatically.

– Supported types are controller blocks (FCs, FBs), PLC data types, HMI

images, HMI faceplates, HMI UDT, scripts).

– Subordinate elements are automatically typified.

– Types are versioned: Changes can be made by creating a newer version.

– There can only be one version of a used type within a controller.
