How Do You Create a Tag?
From the main panel of the Tag Configuration Editor, press one of the
following buttons: Create Analog Tag(s)…, Create Discrete Tag(s)…,
Create String Tag(s)…, or Create Bit Array Tag(s)…. A separate
window prompts you to define a new tag. The tag name must be unique
within a given configuration (
.scf
) file. Select OK on the pop-up window
when you finish creating the new tag, or Create New Tag to finish creating
the new tag and create another tag of the same type. Any changes are not
written to disk until you select Save from the File menu. For step by step
instructions on using the Tag Configuration Editor to create a tag, see
Activity 3-1, later in this chapter.
How Do You Edit a Tag?
From the main panel of the Tag Configuration Editor, select one or more
tags from the tags listed and press the Edit Tag(s)... button. A separate
window displays the attributes for the tags you select, which you can then
edit. When you finish editing a tag, select OK to save your changes and
return to the main panel, Edit Next Tag to save your changes and go on
to the next tag, or Cancel to discard your changes and return to the main
panel. Selecting Cancel only cancels the changes made to the current tags.
Any changes you make are not permanent until you save the configuration
file.
You also can use a spreadsheet to edit multiple tags. Use File»Export… to
export the tag information to a spreadsheet file, edit the fields, and then use
File»Import… to import the tag configuration information from the edited
spreadsheet file. For more information, see the section
Spreadsheet Files for Tag Configuration?
in this chapter.
How Do You Delete a Tag?
To delete a tag from a configuration, select the tag(s) from the main panel
of the Tag Configuration Editor and press the Delete Tag(s) button, and
then save the SCF. Tags that will be deleted when you save the SCF are
marked with a trashcan symbol. The Delete Tag(s) button also serves as an
Undelete Tag(s) button if all selected tags have a trash can symbol. If you
decide you want to keep one or more deleted tags, select those tags and
press the Undelete Tag(s) button.
