The tag data type imports tag and tag group names from a tag configuration 
file (

.scf

). When you launch BridgeVIEW, the tag data type list of 

available tag names and tag group names is automatically updated from 
your default 

.scf

 file. The default 

.scf

 file is the last file you edited in the 

Tag Configuration Editor. If the list of names is empty, you have no default 

.scf

 file.

To change the currently selected 

.scf

 file, right-click on the tag control, 

indicator, or constant, and select Tag Browser…. Press the Browse… 
button to bring up a dialog box from which you can select the 

.scf

 file you 

want to use. This is possible as long as the BridgeVIEW Engine is not 
running. When the Engine is launched, the Tag Browser runs the currently 
selected 

.scf

 file. You cannot change the current 

.scf

 file until you stop 

the Engine.

You can create, edit or copy a tag by right-clicking on the tag control, 
indicator, or constant, and selecting Create Tag…, Edit Tag…, or Copy 
Tag…. Selecting any of these options invokes the Tag Configuration 
Editor. Any new or changed tags are automatically saved to the 

.scf

 file, 

and the list of available tags is then updated. For more information about 
the Tag Configuration Editor, see Chapter 3,
