The import function makes it possible to load user function blocks (uf7 files) from a
folder. This function is available in the Programming view.
In order to be able to import user function blocks, all open user
function blocks must be unmodified.
If they are not, the following message will be output: If open
user function blocks are modified, an import will not be pos-
sible. Please save all modified user function blocks first..
Select a uf7 file and click on "Open"
The selected user function block will be added to the user function block management
group only if it meets certain criteria.
The following messages can occur:
User function block is already found in easySoft 7.
l
You do not need to import it. Do you want to select a different file?
A user function block with different content is already found in easySoft 7. Since it is
l
used in the project and the function block interfaces are different, the import is not
allowed. Do you want to select a different file?
A user function block with different content is already found in easySoft 7. This user
l
function block is open for editing, meaning that an import is not possible. Do you
want to select a different file?
The following applies to these three scenarios:
No:
The import will be aborted
Yes— You will be able to select a different file
A user function block with different content is already found in easySoft 7. Do you
l

Yes— The existing function block will be replaced with the imported function block
