Eaton easyE4 User Manual

6. Function blocks
6.3 UF - User function block
6.3.8 Exporting a user function block
User function blocks can be saved in a separate folder as a uf7 file. The"Export user
function block" menu option will become available if a user function block call is
selected or the programming view for a user function block is open.
Before the user function block is exported, it will be subjected to a plausibility check.
Please note that it will only be possible to export the function block if it does not con-
tain any errors. Finally, if the function block is protected with a password and is not
open, a prompt asking you to enter the password will appear.
A dialog box will appear and ask if you want to edit the user function block's name,
version, password, and/or comment before exporting it.
Yes:
Yes: The "Edit user function block settings" dialog box will appear. Please note that if a password was
previously set for the user function block, you will need to enter it first. If you do not enter the password,
a prompt will appear asking whether you still want to export the user function block.
No:
No: The "Select user function block folder" dialog box will appear. You can then select the folder where
you want the user function block's uf7 file to be saved.
If the selected folder contains any items (files, folders, archives) with the exact same
name as the user function block being exported, you will not be able to notice this in the
"Select user function block folder" dialog box. Accordingly, make sure to first check
whether the selected folder is suitable for saving the file.
Clicking on the Select Folder button may result in any of the following scenarios if
there is a problem:
In the five cases below, you will need to select a different folder.
1. The selected drive is not ready or is write-protected.
2. The selected drive does not have enough free memory.
3. The selected folder cannot be accessed.
4. The selected folder is write-protected.
5. The selected folder already contains a file named UserFB_V1_01.uf7.
If the aforementioned checks are all completed successfully, the user function block
will be saved and the user interface will be refreshed in the Programming view and in
the list of operands and function blocks if applicable.
6.3.8.1 Plausibility check
When exporting a user function block, a user function block check that determines
whether the user function block can be executed in the easyE4 device's current
state will be triggered. This is especially necessary for user function blocks pro-
grammed using ST, as entering impermissible operands is possible in these cases.
The export function will generate a uf7 file only if the user function block is execut-
able. In this case, the file will contain not only the actual user function block, but also
all required management data.
