Designating Identifiers

Identifiers are names of variables and programming objects (for example programs, function blocks, and methods) and names of other objects of the application and project. There are rules that you must follow when assigning identifiers. Furthermore, there are also recommendations to help you designate uniform and expressive identifiers.

You designate variables identifiers in the variables declaration. These identifiers can e changed in the declaration section of the programming object. You designate identifiers for programming objects and other objects in the dialog box when adding the object. You can change the identifier of an existing object of the application or of the project in the properties dialog of the object. However, you cannot change the identifiers of objects that can be available only one time per application or project (for example, the Library Manager and ImagePool identifiers).
