Tagging devices and points

Tags on devices and points provide additional semantic information, making it possible to create hierarchical navigation schemes and to enhance the analysis of historical data. You may add more than one tag to a device or point and use tag groups to add a predefined collection of tags in a single add action. The Niagara Tagging Guide documents how to create tag dictionaries and apply tags to system objects.

Prerequisites: You have a TagDictionaryService in your Services folder. The tag dictionary you are using contains the tags you need. You have discovered devices and points and have the appropriate device or point manager open discovered objects in the Database pane.

Perform the following steps:

Select the devices or points to tag and click the TagIt button at the bottom of the view.
The Edit Tags window opens.
Select the dictionary from the option list in the top left corner .

TIP: In the Search property, you can use a shortcut to designate the dictionary. Type hs: for Haystack, n: for Niagara, and similarly for other dictionaries.

The top half of the window shows a list of tags available from the selected dictionary.
Use the filter fields as needed to limit the number of tags displayed. For example:
- Type in the Search field to filter by tag name. Tags are filtered immediately as you type.
- Select an option from the option list to filter based on validity options (Show All, Valid Only, or Best Only).
Add any number of tags to suit your needs (such as, n:device, hs:geoState, my:bldgRef, etc.) using either of the following methods:
- To add an individual tag from a tag dictionary, select one or more tags in the Tag Dictionary (upper) pane and click Add Tag to assign the selected tag(s) to the device
- To add a predefined collection of tags from a tag dictionary, in the Tag Dictionary (upper) pane in the dialog, scroll down to Tag Groups and select a tag group, and click Add Tag to assign the selected collection of tags at once.
The assigned individual tags and added tag groups are listed on the Direct Tags tab in the lower half of the window.
Edit any tag value propoerties, as appropriate, and click the Save button to save the added tag assignments.
Optional: For tags that have Ord type values (such as hs:siteRef), refer to the following steps as an example of how to add a link to your tag.
1. Click the option list arrow located to the right of the tag value field.
2. Select the appropriate link type from the options menu.
3. Browse to the desired link and select it.
4. Select the Handle option and click OK.
