Library namespace
Scope operator: Extension to the IEC 61131-3 standard.
The library namespace can be used to explicitly access the library components.
Example: If a library which is included in a project, contains a module "fun1" and there
is also a POU "fun1" defined locally in the project, then add the "namespace" of the
library can be added to the module-name in order to make the access unique. The
syntax is: ., for example "lib1.fun1".
By default the "namespace" of a library is identic with the library name, however you
can define another one either in the Project Information when creating a library
project, or later in the Properties dialog for a library.
Example:
There is a function "fun1" in library "lib". There is also a function "fun1" declared in the
project. By default the namespace of library lib is named "lib":
res1 := fun(in := 12); // call of the project function fun
res2 := lib.fun(in := 12); // call of the library function fun
Enumeration name
Scope operator: Extension to the IEC 61131-3 standard.
The type name of enumerations can be used to disambiguate the access to an
enumeration constant. In this case "." precedes the constant
name. So it is possible to use the same constant in different enumerations.
Example:
The constant "Blue" is a component of enumeration "Colors" as well as of enumeration
"Feelings".
color := Colors.Blue; // Access to enum value Blue in type Colors
feeling := Feelings.Blue; // Access to enum value Blue in type Feelings
