Creating elements (e.g. user blocks) for library

The element required within a library must be created within a →project. Create this element as you would any element (e.g. a →POU or →data type) that you would use within the project but with the following difference:

Use namespaces for the element per library – if the usage of a namespace is possible.

The usage of →namespaces ensures the unique identification of the elements. This will help to avoid name conflicts, when e.g. user blocks from the library are used in the application.

Recommendation by logi.cals for such namespaces: com.company-name.library-name for the syntax of a qualified name – If required, insert more →IEC identifiers after library-name (each separated by . from each other).
Example 1: com.CompanyA.Controller
Example 2: com.CompanyA.Controller.Embedded

logi.CAD 3 supports the following elements for a library:

Language	Starting points for more information
→ST	Creating application in ST Supported ST-syntax, in particular: Namespaces in ST Declaration of a function block in ST Declaration of a function in ST Declaration of a data type in ST Declaration of an interface incl. method prototypes
→FBS	Creating POU in FBD Creating FBD-logic Namespaces in FBD Creating the interface in the interface editor
→LD	Creating POU in LD Creating the ladder diagram Namespaces in LD Creating the interface in the interface editor

Restriction

→C or →C++ blocks (see "Integrating C-code and/or C++-code into the application (deprecated)") are not supported as elements for a library.
Valid for logi.SAFE libraries and logi.WEB libraries: See "Peculiarities for logi.SAFE/logi.WEB libraries".
