Programming
Editing User-defined Function Blocks After Creating a Program
190
The following diagram shows how the program will appear if the Logic Editor
is started in this status.
A user-defined function block without a file will appear as a question mark (?)
and the connections will be deleted. Editing operations (copy, paste, undo,
redo, etc.) cannot be used for the user-defined function block. Also, the pro-
gram cannot be saved or downloaded after editing.
If the user-defined function block file is missing, import the user-defined func-
tion block. The program will not be automatically updated, however, if the
user-defined function block is imported with the program open. Close the pro-
gram and open it again to correctly display the user-defined function block.
The following table shows which functions require user-defined function block
files and what will happen if the function is executed without the file.
