3wwwww/bb where
wwwww = word offset 00001 to 65535 (decimal)
/bb = bit offset in word 01 to 16 (decimal)

4

word
read only

4wwwww/bb where
wwwww = word offset 00001 to 65535 (decimal)
/bb = bit offset in word 01 to 16 (decimal)

Note: Digital tags support only bit addresses.

Important:

Because digital tags with References 1, 3, or 4 are
read-only, they can only be assigned to display objects
(e.g. Numeric Data Display). An error will be generated
when you validate the application if a tag with
Reference 1, 3, or 4 has been assigned to an input
object. For more information about types of objects, see
Chapter 9, “Creating Objects,” in the PanelBuilder
1400e Configuration Software for Windows User
Manual,
Publication Number 2711E-819.

Configuring a String Tag

1. If the tag is part of a folder, select the folder in the folder

hierarchy. The folder name appears in the Name field and is the
first part of the tag name.
