Programming Section 6-3
• When the No Button is clicked, the function blocks and connections con-
nected to the outputs of the corresponding user-defined function block will
be deleted, as in the following figure (output tags and connections to jump
addresses will not be affected).
• If the Yes Button is clicked, changes to the user-defined function block file
will be updated in the programming.
If changes to the user-defined function block affect the function block exe-
cution sequence (e.g., newly adding or deleting parts of the function
block), the user-defined function block outputs and the sequence of con-
nections connected to function block inputs may be changed.
The following figure shows an example of the above. The figure at the left
shows the condition before the changes.
Note (1) Thoroughly check performance using the actual system after changing a
user-defined function block that is used multiple times in the program.
(2) User-defined function blocks cannot be imported, saved, deleted,
checked, or edited by any user (e.g., by a guest account) other than the
Windows administrator. Perform these operations immediately after log-
ging on to Windows as the administrator.
