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,

HMI Function Reference

selection dialog box displays all the tags configured in the currently
