Tags and the Project Database
After creating a tag, you can use it anywhere within the project, and you can use the same tag for more than
one object or attribute.
Project Tags Folder
The Project Tags folder contains all tags created and customized by the user. You can create project tags for
displays, to read from and write to field equipment, for control, to perform mathematical calculations, and so
forth.
To update a list of project tags, right-click on the Project Tags folder (or Datasheet View icon ) and select the
Refresh option.
Important: Before deleting a tag, we strongly recommend using the Object Finder tool (on the
Home tab of the ribbon) to verify that you are not using the tag in another part of the project
(screens, math sheets, so forth). If you delete a tag from the project database that is being used in
another part of the project, you will cause a compiling error and the project will function poorly.
To create a new tag, right-click on the Project Tags folder, the Tag List sub-folder, or Datasheet View icon and
select Insert Tag from the shortcut menu. You also can click Tag on the Insert tab of the ribbon.
The New Tag dialog displays, as shown in the following figure:
Use this dialog to specify the following parameters:
New Tag dialog
• Name field: Type a name for the new tag. The first character must be a letter and you can use up to 255
characters in the name.
• Array Size field: Type a value to specify the size of the tag. Any size greater than 0 implies that the tag is an
array.
• Type combo-box: Select a standard tag type from the list (Boolean, Integer, Real, or String). You also can define
new types as structures formed by the classes.
• Description text box: Type a tag description for documentation purposes.
• Scope combo-box: Click to select one of the following options:
• Local: Select if you do not want to share the information in this tag over the Internet.
• Server. Select if you want to share the information in this tag over the Internet.
These options have no affect on projects that do not have Web capabilities. If you select a Scope option for a
project with Web capabilities, then any object property using the Local tag will not work properly over the
Web.
Note: You must create unique tag names. You cannot create a tag that uses the name of an existing
tag.
You can view or edit the properties of a tag from either of the following dialoges:
• Tag Property dialog: Click Properties on the Home tab of the ribbon when the tag name displays in the Tag
name field or double-click on the tag name in the Tag List subfolder located in the Project Tags folder.
