6.3.9 Replacing a user function block
6.3.10 Deleting a user function block
If the aforementioned checks are all completed successfully, the imported user func-
tion block will be added to the group of user function blocks in easySoft 7.
This function makes it possible to replace a user function block that is being used in the
project with a different user function block with an identical "Interface" configuration.
In order for this menu option to be available, a user function block call must be selected
and the user function block must not be open for editing.
If there are any user function blocks with an "Interface" configuration that matches that
of the selected function block and the latter is not open for editing, the "Replace user
function block" dialog box will appear and the user function blocks that can be selected
as replacements will be shown as a list in a pane.
You can then use the "Replace area" section to specify which user function block calls
should be replaced:
The selected user function block only
l
All instances of the selected user function block in the current program
l
All instances of the user function block in all programs
l
Clicking on the "Replace" button will replace the original user function block instance(s),
i.e., the calls, contacts, and coils for the original user function block will be replaced
with the selected user function block.
If there are no user function blocks with an "Interface" configuration that matches that
of the selected function block available, or if they are open for editing, the following mes-
sage will appear:
"There are no user function blocks that are suitable as a replacement, or they are cur-
rently open for editing."
The function can be used to remove user function blocks from easySoft 7. Please note
that you will only be able to delete user function blocks that are not being used in the
project and that are not open for editing. If there are no user function blocks that can be
deleted, the Delete user function blocks menu option will not be available.
The following options are available for deregistering / deleting a user function block:
1. Program/Delete user function blocks... menu option
2. User function blocks folder in list of operands and function blocks/Delete user
function blocks... context menu option
3. List of operands and function blocks <name>/Delete context menu option
The following dialog box will appear if you use one of the first two options:
