View and select external access status on the Tag Editor
You can view the external access status of a tag in the Tag Editor. The External
Access column displays the tag as Read/Write, Read Only, or None.
Follow these steps to select multiple rows and set the external access at one time on
the Tag Editor.
1. To select multiple individual rows, hold down the Ctrl key and click the
desired rows.
2. Right-click a selected tag, and then click Set External Access for (tag
name) to select an external access option.
This updates the external access for all highlighted rows that are enabled for
changing external access.
See External access availability on page 70 for considerations when the External
Access column is unavailable.
Find a base tag with Go To
You can only change the external access setting of an alias tag through its base tag.
The Go To command on the Search menu of the Logix Designer application is a
convenient way to find the base tag among all the cross-reference records.
Follow these steps to locate a base tag.
