If the BridgeVIEW Engine is loaded, you can view the tags currently 
loaded with the Tag Browser. If the BridgeVIEW Engine is not loaded, the 
Tag Browser displays the currently loaded 

.scf

 file. Use the Browse… 

button to change the 

.scf

 file.

The Tag Browser is a useful tool if you need to look at how a tag is 
configured while you are building your MMI VIs. You also can use the 
Tag Browser to change the loaded configuration file.

If you want to access the configuration information for a tag 
programmatically, you can use the VIs in the Tag Attributes palette. 
For more information about the Tag Attributes VIs, refer to Appendix A, 

.

What Is the Tag Monitor?

With the Tag Monitor, you can monitor the value, unit, timestamp, alarm 
state, and status for selected tags in the system, as well as write the value to 
an output or input/output tag. You launch the Tag Monitor by selecting 
Project»Tag»Monitor. When you first launch the Tag Monitor, a tag 
selection dialog box displays all the tags configured in the currently 
selected tag configuration file. For more information about configuring 
tags, refer to Chapter 3, 

.

Figure 2-5 shows the Tag Monitor.
