The tag formats of multiple equipment and lines can be changed in a single bulk edit (see Tag Formats). When the tag format of an item is changed, the tag number of the item will be updated to reflect the new format.
-
To edit the tag format of multiple items, select the items, then click Bulk Update Tag Format in the Actions section of the List Tools - Process Equipment or List Tools - Process Lines tab.
The Process Equipment Bulk Update Tag Format or Process Line Bulk Update Tag Format window is displayed:

The window displays the current tag numbers of the items selected in the Process Equipment or Process Lines list, with their class names and tag formats (see Class Definitions).
The required tag format to be applied to all listed items is selected from the Tag Format list.
By default, this list is restricted to the tag formats assigned to the classes of the listed items. If the listed items are associated with different classes, only those tag formats common to all those classes are available.
-
Select the required Tag Format from the dropdown list.
-
If required, the class of the listed items can be changed. Uncheck the Lock Class checkbox.
-
The Class Name list then becomes available. Select the required class from this list. The Tag Format list will then list the tag formats associated with the selected class. Select the required format.
-
Once the required tag format has been selected, click Next.
The window then lists the items with the proposed tag numbers, that means, the tag numbers of the items with the selected tag format applied.

The current tag number, and current and proposed classes and tag formats are also displayed.
-
Only those items with their Select checkboxes checked will have their tag numbers changed. They are checked by default. Uncheck Select checkboxes as required. The Select All checkbox can be used to uncheck (and re-check) all Select checkboxes.
-
When the required items have been selected, select Next.
The following warning message is displayed, warning that the new tag numbers created by this procedure may duplicate those of other items.

-
Select Yes to continue, or No to close the message without continuing.
If Yes is selected, the changes to the tag numbers then take place.
A log of the changes is then displayed, listed successful and failed changes to tag numbers.

-
Select Close to exit the window.
