The Tag Browser is the central location for interaction with all types of Tags on your system. It gives you full view of the Tags including the current value, datatype, and any traits. When panels are in their default configuration in the Designer, the Tag Browser appears on the left side.
As of release 8.1, the Tag Browser has been updated with a new design for ease of use. Tags and UDT Definitions now have their own tabs. The Tag Provider Selector enables you to view Tags for a specific Tag provider. There is a new interface for Creating Tags. Many other improvements have been integrated, including icons for each Tag type.
The Tag Browser is set up in an interactive tree structure with folders that can be expanded or collapsed to view more Tags. Click on the Expand 
icon to expand any folder or the Collapse 
icon to collapse the folder. In the example below, the pH Tag for Tower2 was expanded.
The Tag Browser toolbar has several options for working with Tags.
The Add 
icon opens a context menu showing all the options to Browse Devices, add a Tag, Folder, UDT Instance or a UDT Definition. The new object is added under the Folder you selected, or as a sibling to the Tag you selected. This button is disabled if there is no selection.
With the Browse Devices, you can browse to find external PLC or OPC Tags. Click the Add icon at the top of the Tag Browser to open the Browse Devices. You can then select Tags and move them to the Tag Browser to be used in the Ignition system. For complete information, see Creating Tags.
Clicking on the Search 
icon in the Tag Browser will open up the Designer's global Find/Replace screen. In the the example below, we searched for the Ramp9 Tag and limited the search to the default Tags. Results are shown at the bottom of the screen. For additional information, see Find and Replace.
The Refresh Providers 
icon refreshes all of the Providers in the Tag Browser. This is useful if you or others have modified Tags and do not see an update. In general, this button is not used very often.
The Tag Provider Selector is a dropdown menu with a list of available Tag Providers. Use this selector to view the System Tags, Vision Client Tags, default Tags, or other Tag Providers you have in your project.
On a new install of Ignition, a single "default" Tag Provider is created for you, but there are no Tags added to the "default" provider initially. You'll notice the "default" provider is in bold. The bold entry in the dropdown list is determined by the Default Provider for the project. You can change the default provider in Project Properteries > Project > General > Tag Settings > Default Provider. Save and restart the Designer, and the next time you open the Tag Provider in the dropdown of the Tag Browser, a different Default Provider will be displayed in bold.
System, the Browsing Devices under the Add icon is disabled.
A More options 
icon on the upper right of the Tag Browser, opens a dropdown menu of additional options.
In the Tag Browser, the 
Edit Tag Grouppens the Tag Group Editor window. Tag Groups dictate the rate of execution of Tags. This is where you set up your Tag Groups and scan rates. See Tag Groups for more information.
Ignition can export and import Tag configurations to and from the JSON ( JavaScript Object Notation ) file format. Use the 
Import icon or 
Export icon to import and export Tags in this Gateway. See Exporting and Importing Tags for more information.
The Tag Browser displays the Value and Data Type. The Value type is set by default. To toggle any of the options, click on the 
Column Selector icon, then click the checkbox.
In the example below, the Tag values are shown next to the Tag names.
Editing Tags is done mostly through the Tag Browser. The Tag Browser allows you to right click on a Tag or folder to perform any of the following functions. Different objects will have different options available. The special Data Types folder is slightly different than a regular folder and will have even fewer options.
