Object ‘Library Manager’

Use the library manager in order to add libraries to your project and to adapt their properties.

You can add the library manager as an object in the POU view (global) or application-specific in the device tree. You can insert only one library manager at these positions.

The library manager is opened using the Edit Object command or by double-clicking on the object.

The library manager editor is divided into three windows.

• Top window: list of the integrated libraries
• Bottom-left window: modules of the selected library in tree structure
• Bottom-right window: details for the selected module

List of the integrated libraries

The top part of the library manager shows you the libraries currently integrated in the project. If a library depends on other libraries (referenced libraries), these referenced libraries are automatically integrated.

Libraries that were automatically inserted into the project by a plug-in are displayed by the library manager in gray lettering. Libraries inserted manually using the command Add library… are displayed in black lettering.

Name	Title, version and optionally the company name. These details correspond to the settings of the Summary tab of the Project Information dialog box. Library symbols :CODESYSV3 library (contains version information). : referenced library : CODESYS cannot find the referenced library file or the file is not a valid library file. Note here the messages in the Message window in the Library Manager category. The name of the missing library is underlined with a blue wavy line. If the node of the higher-level parent library is closed, the name of the parent library is underlined with a gray wavy line. : licensed library for which no valid license is currently available.
Namespace	You must use the namespace of the library as the prefix of the identifier in order to allow unambiguous access to a module that exists several times in the project. The namespace is also necessary if the use of this prefix is forced by the library property LanguageModelAttribute "qualified-access-only" (unambiguous access to library modules or variables). You can modify the standard namespace of an integrated library for local use (within the project) in the Properties dialog box.
Effective version	Version of the library that is currently used in the project in accordance with the definition in the library properties.

Contents of the library

In the bottom left part of the editor the modules of the currently selected library are also represented in a tree structure. The usual sort and search functions are available to you in a menu bar.
