Click View > Tag Editor to open the Tag Editor pane, as displayed on the right:

Here, all created tags, and their designated names, data types, connected I/O devices, assigned I/O addresses, initial values, persistent attributes, and descriptions are shown. Users can create, group, edit, paste, copy, cut, and delete tags from this pane by clicking the icons or using the right-click menu. The user can also click the Tag Count icon to see how many tags of each type or device have been created.

The Tag Editor pane can be undocked by dragging the pane's header to be placed to the user's liking.

To add a tag group, click the Add tag group icon in the Tag Editor pane. After pressing the button, a text field will open in the Tag Editor pane where a name for the tag group can be assigned.

If the user has too many tags in a single pane, finding and managing individual tags may be challenging. Tag groups allow users to organize tags based on category, with a tree structure for subordinate tags. The grouped tags are displayed and managed in the Tag Editor pane.

Tags can be defined and configured inside the Tag Editor pane. Within a Canvas project, tags can be accessed and updated by UI elements, external devices, scripts, and various utility functions (recipes, alarm groups, etc). Canvas currently has three types of tags: Remote, Virtual, and Virtual (Runtime Only). Remote tags write and read their value to and from external devices. Virtual tags allow access to the Xpanel's gateway and can be accessed by other devices through the Data Server feature. Virtual (Runtime Only) tags are only used internally within the Xpanel. They simulate devices and processes, process input data, and store data describing the application state.

Each tag supports boolean, analog, and string tags with the following data types: BOOL, REAL, LREAL, SINT, INT, DINT, LINT, USINT, UINT, UDINT, ULINT, and STRING.

Tags can be bound to objects and their parameters. Within Canvas projects, tags can be bound to specific values in objects, and some objects require tags to be bound to them before they can function properly. To bind a tag to an object parameter, users must hover over any parameter that can have a tag bound to it. Once hovering over, there will be a Link icon, and clicking on this icon will open the Binding Properties window. Clicking the Tag field will open a tag window and display all tags in the project. Users can select a tag from the page, which will then be bound to the parameter. Users can pick the direction for how the tag will function. Users can pick Tag to Property, Property to Tag, or Bidirectional.

Users can also Drag and drop the tag onto the parameter. To bind a tag to a property, click and hold the tag's name from the Tag Editor. While holding, drag onto the property that the tag needs to be bound to, and once the Link icon appears, let go of the tag, and it will automatically be bound to the property. After this, no further input will be required for the tag unless necessary.

Depending on the tag type, users can also add Formatting Options. These options can specify how many decimal places, how many leading zeroes, or even if the base should be decimal or hexadecimal, or if there should be a thousand separators. These will only work on tags that are bound to Text.

Some objects can be bound by just dragging the tag onto the object. This will automatically bind the tag to a specific property of the object. An example of this would be a Text Box. When the user smart binds to a Text Box, it will automatically bind the tag to the text. To smart bind, click and hold the tag's name from the Tag Editor. While holding, drag onto the object that the tag needs to be bound to, and the cursor will change, indicating it can be bound to. Once the cursor changes, let go, and it will be bound, requiring no further input on the object. Objects that have a bindable parameter in basic properties will be able to have tags smart bound to them.

Custom Expressions can be used on object parameters. Custom expressions can be used in place of a tag to have an object parameter function in a specific way. There are currently six expressions that are possible in the Custom Expressions. There is a Condition Map, Boolean Value, Multilanguage String, Scale Tag Value, Date/Time String, and Custom Expressions. Each of them can perform a specific function; for more information on what they do, please look at the Appendix, as there will be more details on each Expression.

1. Select the tag(s) or tag group(s) to be copied to a spreadsheet. The user can select multiple tags using the [Ctrl] + Left-click. The subordinate tags are also selected when the user chooses a group tag.

2. Copy ([Ctrl] + [C]) the selected tags to the clipboard.

3. Paste ([Ctrl] + [V]) the contents directly into a spreadsheet. Each column stores a different tag attribute. These tag attributes match the ones described in the Edit Tag window. A detailed description of the tag attributes and their intended functions can be found here. Note that the associated attributes of Encoding, Clamp Mode, Deadband Type, and Scale Mode populate in a spreadsheet, even if their parent attribute is disabled.

4. Edit the tag(s)/tag group(s) in the spreadsheet. Users can automatically create consecutive tags with a spreadsheet's increment/decrement feature. Note: Most Auto-increment features do not work for hexadecimal values. Please double-check that word and bit addresses for real tags follow the correct device address format.

5. Select the rows in the spreadsheet to copy.

6. Copy ([Ctrl] + [C]) the rows to the clipboard and paste ([Ctrl] + [V]) them to the Canvas Tag Editor pane. The pasted contents will replace tags with the same name. All tag attributes must be copied for Canvas to paste into the Tag Editor pane.
