Publication 2711E-6.12 – August 1997
Addressing Syntax for Devices Using 6-digit Addressing:
Reference Operations Addressing Syntax
3 word
read only 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.
