When selecting the Global Replace tool from the ribbon Home tab Tags group, the following dialog opens:

Global Replace Tags dialog

Note: You must close all documents (screens and worksheets) before executing this command.

From the Global Replace dialog, you can replace any tag(s) from all documents (screens and worksheets) of the whole project. You can edit both the From and the To column.

When replacing composed tags (array size > 0 and/or Type = Class), you can configure a specific array position (for example, TagA[1] ) or class member (for example, TagB.MemberX ) or both (for example, TagC[3].MemberY ). If you configure only the Main Tag Name (for example, TagC ) in the From column, all tags from this main tag will be modified for the tag configured in the To column.

If an invalid replacement is configured (for example, replace the Main Tag tag from a class type tag for a simple tag (not a class tag), the OK button will be disabled. When the OK button is pressed, the tags configured on the Global Replace dialog will be replaced in the order that they were configured on the dialog interface.

When changing the tag name on the Project Tags folder, you will be asked if you intend to replace this tag through the whole project.
