About Tagging Components and Lines

You can tag components and lines to identify them as unique items in a project.

Depending on how your administrator set up your project, you may be prompted to assign tag information as you place components or lines. However, if you do not know all of the tagging data at that time, you can dismiss the prompt and tag a component or line whenever you have the data available.

You can assign or modify tag information to a component or line by using the ribbon, the Properties palette, the shortcut menu, or the Data Manager.

Note:

Do not use Find and Replace to modify tag information.

Components such as equipment, nozzles, valves, instruments, and pipe lines have the following default tag formatting:

• Equipment tag (Type-Number). Defined by default with a type property and a number (for example: P-100).
• Equipment tag 2 (Area-Type-Number). Defined by default with an area property, type property, and number (for example: 25-P-1000).
• Hand valve tag (Code-Number). Defined by default with two letters representing a valve code and a number (for example: HV-100).
• Nozzle tag (N-Number). Defined by default with one or more letters representing a nozzle code and a number (for example: N-1).
• Instrumentation tag (Area-Type-Number). Defined by default with an area, type, and loop number (for example: 51-PT-100).
• Line number tag. Defined by default with a line number (for example: 100).
• Pipeline tag (Size-Spec-Service-Line Number). Defined by default with size value, spec, service, and line number (for example: 6"-C1-P-10014).

If your tag formats are different than those listed above, your administrator may have changed the formatting. For more information about the tag formats that are set up for your company, see your administrator.

When you copy a component or line, or create a new line by inserting equipment into an existing line, the new item is assigned a temporary tag that contains a question mark to differentiate it from the original tag. For example, if the original tag for a component is P-100, the temporary tag might be P-100?.
