Verification Required Program verification can be completed even without the function block
file once the file is downloaded to the controller, but the function block
configuration cannot be checked.
Edit the program Required A warning message will appear if the Logic Editor is opened without the
function block file. The user-defined function block without a file will
appear with a
icon and any connections to or from it are deleted.
Editing features such as copy and paste are not available. If the program
is edited in any way, it cannot be saved or downloaded.
Apply program Required This command cannot be executed without the user-defined function
block file.
TIP If you import the user-defined function block file with the program open, it
will not automatically update. Close the program and open it again to
display the function block correctly.
IMPORTANT Always check the original program after editing user-defined function
blocks. If you created a user-defined function block, used it in the original
program, and edited the function block after the original program was
saved, the function block occurrence in the program is not updated.
