3. Select the file and click the Open Button.
The imported user-defined function block will be displayed in the Logic Ed-
itor Object List.
User-defined function blocks that are no longer required can be deleted.
1. Click the user-defined function block to be deleted on the Logic Editor Ob-
ject List.
2. Select Function Block – Delete from the Logic Editor main menu.
Deleted user-defined function blocks cannot be restored. Be sure you do not
need the function block before deleting it.
Project files (*.ncf files) and user-defined function block files (*.fbd files) exist
as separate files. This section describes the relationship between project files
and user-defined function block files.
Apply the program (select File – Apply) in Logic Editor to temporarily save
data for all function blocks used in a program (including those used inside
user-defined function blocks) (see note). This data will include all data
required for NE1A-series Controller operation.
Once you exit Logic Editor and click the OK Button in the NE1A-series Con-
trollers' Edit Device Parameters Dialog Box, the data will be saved to a project
file.
Project files can still be read normally even if there are no user-defined func-
tion block files.
Configurator data can still be downloaded normally even if there are no user-
defined function block files.
Once programs that include user-defined function blocks have been down-
loaded to the NE1A-series Controller, they can still be uploaded normally
even if there are no user-defined function block files.
User-defined function blocks are displayed.
A user-defined function block can be edited
by right-clicking it and selecting Edit from
the pop-up menu.
User-defined function blocks cannot be
edited, however, once they have been
allocated in a program.
