At a Glance

Libset (set of libraries) comprises all libraries, families, functions and variables (I/O data structures) that can be used to develop an automation project.

You can only modify the Libset version in the Open project dialog.

Libset Versions

The Libset V10.0 and later are automatically installed with Control Expert.

To install previous Libset versions, start Programs > EcoStruxure Control Expert > Install libset tool.

Creating a New Project

Creating a new project, the latest Libset version is automatically selected for this project.

To modify the Libset version of your project, you have to save your project and open it again with the version of Libset you want to use.

Opening a Project

In general, opening an existing project (STU file) or an archived project (STA file), you can select the Libset version.

Importing a ZEF or XEF file, the latest Libset version is always selected.

The following table describes the default Libset version used to open a project according to the file type.

Modifying the Libset Version

Opening an existing project (STU file) or an archived project (STA file) you can select the Libset version.

The Open dialog provides the following options.

If the Libset version is modified, the project is in modified state.

Upgrade/Downgrade

• Upgrading the Libset does not update the project with the newly chosen libset automatically.

  EF/EFB differences will be displayed during opening the project in the LIBRARY Version Management dialog, where you can update the project.

  You can update the project later as well, using the contextual menu command in the Type Library Manager dialog.

  If you have updated the project, you have to start a Rebuild All . A Rebuild All needs to stop the PLC and to perform a global download.

• You can also downgrade the Libset version.

  There is no consistency check when downgrading the Libset while opening a project.

  So you may not be able to rebuild the project (using a block created in an earlier Libset version, not available in the latest Libset version).

  If the rebuild is unsuccessful, you have to save your project and to open it again with an appropriate Libset .

• If you want to add an FFB which is not yet contained in the current version of the Libset , you have to upgrade the whole Libset.

• A change of Libset version in the Open dialog is memorized in the project.
