At a Glance

The Derived FB Types Import function allows the user to import one or several DFB types. The imported DFB can be either write protected or not write protected. If the DFB is write protected, the DFB elements can only be accessible in read only mode. If the DFB has version protection, the version number is only accessible as read only. Any nested DFB or DDT that are used to compose the imported DFB is also be imported.

If the imported DFB type already exists in the application, a pop-up window appears to allow the user to either:

  • keep the element from the current project,

  • replace the project element with the one in the import file,

  • rename the imported element.

Importing a DFB type

A message tells you that the import is complete.

If any errors occur during import, you are informed of these by a message in the Output Window.
NOTE: If the imported duplicate DFB is not renamed, the DFB might not function as expected. Multiple reuse of the same instance of either the imported DFB or copied DFB is not recommended because it could lead to improper execution of the DFB.
