Object: Library Manager

Symbol:

The Library Manager lists all libraries which have been integrated in the project for creating applications. It provides information about the type of library, its properties, and its contents.

You can expand or collapse the list of integrated libraries, as well as edit library properties for non-dependent libraries.

The Library Manager consists of three views:

Upper view: List of the integrated libraries
Lower left view: Tree structure with all modules of the library selected in the upper view
Lower right view: Documentation for the library POU selected in the tree

For more information, see: Using Libraries and Information for Library Developers

List of integrated libraries

If a library depends on other libraries, then these referenced libraries are automatically integrated.

Displayed in gray fonts	A plug-in was used to automatically add the library to the project.
Displayed in black fonts	The Add Library command was used to automatically add the library to the project.
Name	Display of the integrated library in the following syntax: <placeholder name> = <library name>, <version> (<company>): <placeholder name>: When the library is a placeholder library, the placeholder name is before a =. <placeholder name> = (unresolved): The placeholder library is not resolved. <library name>: Name of the library that is used for management in the library repository <version>: Version that was referenced at the first time it was integrated (<company>): Vendor (optional)
Namespace	Namespace for unique access to the contents of the library It is prepended to a module identifier for this purpose: <namespace>.<library POU identifier> The namespace usually matches the library name. Note: If the library has the property `LanguageModelAttribute "qualified-access-only"`, then you have to access the library POU in the application code by means of the namespace. Qualified (unique) access is enforced. You can modify the standard namespace for local use (within the project) in the Properties dialog.
Effective version	Version of the library after the resolution This version of the library is used in the application. Requirement: The Library Manager exists in the Devices view and a placeholder library is selected. Example: `3.5.10.0`
	Symbol with tooltip to notify about the current resolution of the selected placeholder library which deviates from the default Example when the Library Manager is in the Devices view: This placeholder is explicitly redirected to this version (see the Placeholders dialog). Example when the Library Manager is in the POUs view: In the 'Device_1' device, the placeholder is resolved to 'VisuElemsAlarms, 1.0.0.0 (System)'.
	Library which is signed with a trusted certificate (compatible with CODESYS >= V33.5 SP15)
	Library which is signed with a trusted certificate, but references at least one unsigned library
	Library which is signed with a private key and token (compatible with CODESYS >= V33.5 SP15)
	Library which is not signed, or signed with an untrusted or expired certificate In the case of an untrusted certificate, the Trust Certificate command is provided in the context menu.
	Unavailable library or unresolved placeholder library Hint: Assign an available library to the placeholder. To do this, click the command icon. There you can edit the placeholder and, for example, assign the newest version or another library.
	Library that is defined as optional and not currently available
	Library whose status is being determined
	Licensed library for which no valid license is currently available
	Library symbol for a library that cannot be loaded because its signature (encryption) could not be verified
	Libraries which are managed by the Library Manager in the POU pool

Table 15. Commands in the Library Manager

Add Library	Opens the dialog for selecting a library All libraries installed in the library repository are offered.
Delete Library	Removes the currently selected library from the project
Properties	Opens the dialog for the display and editing of the properties of the presently selected library
Details	Opens a dialog with details for the presently selected library (general information, contents, properties, license information)
Try to Reload Library	If you select a library marked as not found, then you can try to load it into the project again using this command.
Download Missing Libraries	Opens a dialog which displays the libraries marked as missing in the Library Manager. On download, CODESYS scans for these libraries in the download server specified in the project options. After being downloaded, they will be installed automatically. As long as this dialog is open, the recently installed libraries can be uninstalled.
Placeholders	Opens the Placeholders dialog. The current resolution is displayed and you can edit them there.
Library Parameters	Opens the Library Parameters dialog. The parameters of the libraries which exist in the Library Manager of the application and of the POU pool are displayed there. You can customize the parameters in this dialog.
Library Repository	Opens the Library Repository dialog for installing and uninstalling libraries and for defining library locations
Icon Legend	Opens the Information dialog with a legend of the icons that display the current status of a library in the list of integrated libraries (see above)
Summary	Opens the Library Summary dialog All libraries referenced in the project are displayed in a tree structure in the dialog, and those libraries which reference these libraries. Display all occurrences in library hierarchy and close dialog command: In the editor of the Library Manager, the libraries in the open tree structure are marked which reference or use this library. Requirement: A library is selected. The Information dialog is closed afterwards. This command is also executed when you double-click a library. . Display of the libraries Managed Library: Name and version of the library Number of Occurrences: Number of locations where this library is referenced by other libraries When you click + for a library, the libraries, which reference this library, are displayed in the next level down.

Trust Certificate

Only in the context menu of a library selected in the Library Manager, in which the library has been signed with an untrusted certificate

The command turns the untrusted certificate into a trusted certificate and the prepended icon changes from to .

Export Library

Available only in the context menu of a library selected in the Library Manager

Opens the default dialog for saving the library file in the file system

Tree structure of all modules of a selected library

Table 16. Contents of the selected <library name> library

All library POUs which were integrated with the library are listed in a tree structure.

Requirement: A library is selected in the upper view.

Tip

The usual sorting and search functions are available in the menu bar.

Documentation for the library POU selected in the lower left view

Note

The documentation of implementation libraries has to be generated one time. This is done using the Click to update the library documentation command.

Tab: Inputs/Outputs	Interface (inputs/outputs) of the library POU
Tab: Graphical	Graphical display of the module
Tab: Documentation	Documentation for the library POU Note: As a library developer, you need to pay strict attention to the rules for documentation inclusion in "Guidelines for library development". For more information, see: Library Development Summary
Tab: Library Parameters	Requirement: The library project contains an object with library parameters. The Open configuration dialog command is located on the tab. This command opens the Library Parameters dialog.
