Using the Library Manager

7 Library Manager

The library manager shows all libraries that are connected with the current project. The POUs, data types, and global variables of the libraries can be used the same way as user-defined POUs, data types, and global variables.

The library manager is opened with the 'Window' 'Library Manager' command. Information concerning included libraries is stored with the project.

7.1 Using the Library Manager

The window of the library manager is divided into three or four areas by screen dividers. The libraries attached to the project are listed in the upper left area.

In the area below that, depending on which register card has been selected, there is a listing of the POUs , Data types, Visualizations or Global variables of the library selected in the upper area.

Folders are opened and closed by doubleclicking the line or pressing <Enter>. There is a plus sign in front of closed folders, and a minus sign in front of opened folders.

If a POU is selected by clicking the mouse or selecting with the arrow keys then the declaration of the POU will appear in the upper right area of the library manager; and in the lower right is the graphic display in the form of a black box with inputs and outputs.

With data types and global variables, the declaration is displayed in the right area of the library manager.

Standard Library

7.2 Standard Library

The library with "standard.lib" is always available. It contains all the functions and function blocks which are required from the IEC61131-3 as standard POUs for an IEC programming system. The difference between a standard function and an operator is that the operator is implicitly recognized by the programming system, while the standard POUs must be tied to the project (standard.lib).

The code for these POUs exists as a C-library and is a component of WAGO- I/O-PRO 32.

7.3 User-defined Libraries

If a project is to be compiled in its entity and without errors, then it can be saved in a library with the 'Save as' command in the 'File' menu. The project itself will remain unchanged. An additional file will be generated, which has the default extension ".lib". This library afterwards can be used and accessed like e.g. the standard library.

For the purpose to have available the POUs of a project in other projects, save the project as an Internal Library *.lib. This library afterwards can be inserted in other projects using the library manager.

If you have implemented POUs in other programming languages, e.g. C, and want to get them into a library, then save the project using data type External Library *.lib). You will get the library file but additonally a file with the extension "*.h". This file is structured like a C header file and contains the declarations of all POUs, data types and global variables, which are available with the library. If an external library is used in a project, then in simulation mode that implementation of the POUs will be executed, which was written with WAGO-I/O-PRO 32; but on the target the C-written implementation will be processed.

7.4 'Insert' 'Additional Library'

With this command you can attach an additional library to your project.

When the command is executed, the dialog box for opening a file appears. Choose the desired library with the "*.lib" extension and close the dialog with OK. The library is now listed in the library manager and you can use the objects in the library as user-defined objects.

7.5 Remove Library

With the 'Edit' 'Delete' command you can remove a library from a project and from the library manager.
